Tera Term for Windows XP?

Do any of you have a program that I could use to sync my phone to my Computer via usb? I've tried several versions of Tera Term with no success. I reached the point where I was ready to pull all of my hair out and then I remembered... I don't have anyway. Oh well. Please help I really want to upgrade my rom but I want to back up the old first. Thanks, Vern.

i think i don't understand what you're trying to do!?
Don't you use ActiveSync for Syncing with your PC?
And wtf is Tera Term???

This is what I'm trying to do:

1. Get a 128MB SD card. They're cheap - under $20.
2. Insert said card.
3. Go to http://forum.xda-developers.com/viewtopic.php?t=37386 and download the aWizard utility. CID-unlock your phone. (You only need to do this ONCE, even if reflash in the future.)
4. Get a terminal program that can speak over the USB port. There is a patched version of Terraterm out there, along with a few others. You need a way to connect to the device over the USB port as an ascii terminal.
5. Turn off the phone.
6. Holding the CAMERA key, press the power button for 2-3 seconds. Continue holding the CAMERA key until it comes up in the tri-color screen.
7. Connect the USB cable. Wait until ActiveSync tries to start. CTRL-ALT-DEL Windows and kill the process wcescomm.exe (ActiveSync's communication driver)
8. Now start your terminal program and point it at the USB port. Hit RETURN and you should get a command prompt. You are now talking to the phone's boot loader in terminal mode.
9. Type "r2sd all" and hit RETURN.
10. If you get a security level violation, you DID NOT CID-unlock the device. Go back to step #1.
11. The ROM image (all of it) will be written to the SD card. Several messages will be displayed while this is in progress. Note that this is NOT - I repeat - NOT - a filesystem-formatted dump - it is a RAW image of the ROM with some checksum information included. Anything on the SD card will be destroyed - don't do this with a card that has data on it you care about!
12. You can stick this card somewhere to be used for restoring. If you want to save the image off the card to your computer, stick the SD card in your computer and then dump 128MB of the card starting at the front (the actual dump is about 80mb but will always be less than 128MB, so that's "safe".) You will need a tool like "psdread" or any other tool that can do byte-level I/O to the SD card in your PC's reader for this.
To restore a SD-card image dump to the Wizard:
1. Write the image to the SD card. Again, this is NOT a filesystem - its a RAW image! Unless you saved the image to the card from the Wizard initially you will need a tool that can do a raw write to the SD card in your computer.
2. With the Wizard OFF, insert the card into the SD slot.
3. Hold BOTH the CAMERA and VOICE keys and press the power button for 3 seconds. Release POWER.
4. Look CAREFULLY at the Wizard screen. The backlight WILL NOT BE ON! It will tell you to press the VOICE button if you wish to restore the SD card image. This message only appears for a few seconds and the backlight is OFF! If you wait too long you will end up at the tri-color bootloader screen. Press the VOICE button (if you still have it down, let up on it then press again.)
5. The restore will run. Note that the backlight IS NOT ON during this process! You may need a flashlight (or very bright ambient light) to be able to read the progress meter.
6. When the process is complete it will tell you to press "any key". Do so and you're back in the tri-color bootloader screen.
7. Turn off the Wizard with the power button. When you turn it back on, it will hard reset just as if it was brand new off the firmware you just restored.
Note that this is the ONLY way to recover from a bricked phone if you try to load the wrong firmware file using one of the "forcible" methods (e.g. aWizard) on a non-CID-unlocked phone, and have bypassed the normal protection methods as ActiveSync cannot get back in there under these circumstances.
I strongly recommend that if you're going to futz with firmware, that you get yourself a 128MB card, make one of these dumps, and TEST the restore before you play around. This will recover from almost any botch - the only exception is loading a firmware file via some means (e.g. "aWizard") that the phone cannot execute at all.
Note that I do not know if this will get around the "boot loader version is too high" problem - I'm not willing to try it until I have an official T-Mobile update with a newer boot loader.
This same method for both dump and restore works on the SDA as well.
13. Overclocking the MDA (do so at your own risk!)

Don't forget to remove the ";" (without the quotes) at the beginning of the overclock settings in the configuration file!
How fast you can clock it depends on your device, it's just a matter of trial and error. 240 seems to be safe for the majority of HTC Wizard owners. No need for extra tools to wake overclocking up after a soft reset or standby. I haven't noticed severy battery drain, I can easily use my device a whole day and come home with the batterie well over 50% charged.
It's just a great little program. The integrated overclocking comes as a bonus to the tweak that the program was actualy made for, remapping buttons so you can open the start menu without using your stylus and close programs without using the stylus.
Have a look around on the HTC Wizard Blog, there is lots of other stuff that you may find useful.
And Number 4 is WTF Tera Term is. Thanks.

Windows 7 & HTC Drivers Issue

Hi
I have tried the dummies guide concerning updating the HTC USB drivers but had a couple of issues:
1. If I press F8 during the boot process I get an abreviated version of the bois setup which has no selection for turning off digital signing of drivers. I have an ASUS motherboard so to enter the bois I press the DEL key. Whilst in the bios I can see no option for turning off the digital signing. The instructions in the thread simply don't work.
I have done some searching and found web pages that explain how to enter the command window, paste 2 or 3 lines of text to turn off digital signing and put W7 64 bit into a sort of test mode. I have done that and have "Test Mode Windows 7600" in the bottom right corner of my Desktop. I still can't install the HTC USB driver as it brings up an error due to being not signed.
Without installing the new driver I cant change my ROM. There must be others in the same boat having changed to Windows 7. Please help.

Ok a few things:
I'm on windows 7 x64 build 7600, I'm having NO problems, just connect your device in windows let it connect with active sync
Then de-connect your blacktsone, shut it down, and hold volume down button then press start up, it will now start in bootloader mode
Now re-connect and wait for it to get installed by your pc!
If you really DO need htc drivers
Go into your bios
Turn of any quick booting AND turn off full logog display
When windows is starting AFTER the bootscreen you'll get a screen with some sort of TABLE in it with all your hardware and all they're IRQ's
at THIS moment when you see this table press f8
Then you get a boot menu
and you can follow your guide with turning off the signed drivers etcetera!
Great Greet Giblet

wow dude, treat me like the idiot I am. Step by step please.
"Then de-connect your blacktsone" - i guess you mean take out the USB cable?
I wait for it to get re-installed but nothing happens whilst in bootloader and the word serial stays at the bottom of the screen

OMG
Oh my god, I am really frustrated becuase I managed to get it to work with your help but I don't know how. I must have tried everything 10 times without luck then all of a sudden it worked.
If only I knew what I was doing wrong I could pass it along to the next poor sap.
Thanks for your help.

Some options to get a new ROM on your device:
Alternative Option: Run ROM from storage card (this requires HSPL on your device)
- Connect your phone to your pc with the usb cable
- Choose Disk Drive option on your phone when presented with the choice.
- Extract the downloaded rar and if not called BLACIMG.nbh rename the romfile to that (ruusigned.nbh is commonly used so rename when so)
- Copy the BLACIMG.nbh to your phone's storage card via Windows Explorer where it should show up as an removable harddrive.
- Disconnect your phone from the pc once copy has finished.
- Shut down your phone.
- Press Volume Down (left top of phone) and keep it pressed while pressing the Start button (on top of phone) once.
- The bootloader (red,green,blue,white screen) will now start, it will detect the new rom file and ask you if you want to update your current one.
- Confirm and follow instructions on screen
Done.
As for your unsigned drivers i can offer some tips:
- Press F8 after you have seen all your hard drives recognized in the bios bootup screen but before you see the Windows Logo.
- F8 might be set as a bootselector menu by your motherboard manufacturer, if this gets in the way of trying the get to the F8 options from Windows you can disable it in your BIOS (to enter press del)
- If you have Windows 7 Ultimate you are entitled to XP-Mode which is basically a built in virtual machine of Windows XP within Windows 7, some people have been succesfull connection their phone to that XP installation and were able to update via it.
Hope this helps. together with the previous poster's comment you should come a long way, good luck.

Oh lol, guess you just managed, grats on that. for future you could try the alternative option i posted, works garanteed irregardless of operation system.

Solution found, thread closed
In future try posting such queries in the Dummies guide: updating HTC USB Sync Drivers thread. Thats what its there for

Has anyone tried this free sofware SIM unlock?

http://forum.gsmhosting.com/vbb/f606/acer-liquide-unlock-solution-100-working-1092894/
I am confused because the OS update from the global Acer site doesn't create a folder called "qcn" or "01" or "03."
If anyone knows how to get this free unlock working, please educate us. I'd rather not pay for an unlock.

I did not try, but I downloaded the file, and translated the french, not sure what to make of it, I think it could be dangerous if it's for liquid and not liquid e, although, writing nv items on most similar devices should be the same
French to English translation
Flasher / unlocked his Liquid AMSS in Fashion
Render unto Caesar what belong to Caesar:
I would like to thank DNA without him if he was not mistaken in the keys that I have given him, I'd still be looking!
Right now the heart of the matter ...
The Acer software to reverse mode AMSS Tools uses to flash the baseband before flashing the rest of the liquid, you could just put up this system, those with Maleza recovery or at worst by fastboot.
But in any case we could touch the baseband, much less dream of désimlockage its Liquid!
The method I'll suggest is as dangerous as a flash! In fact it is one! So be very careful, no hurry, because even if it is recovered through this method, about 10 minutes of flash is a long time anyway!
With this, any liquid is recovered even those whose method fastboot can not walk alone are not such that the light at all, unfortunately, more vibration and hopelessly lost!
If you still have access to your phone, do a backup!
Otherwise:
0 Download this-> http://www.mcboydesign.fr/media/acer_liquid/amss_mode/amss_mode.zip and unzip it!
1 Turn off your phone if it is not already the case!
IMPORTANT: The drive must be disconnected!
Volume 2 Make (and not-as Volume Recovery!) Picture Power, all at the same time, the liquid will vibrate twice, but nothing appears on the screen!
3 Plug the USB into Liquid on your phone, I do not explain here how to ask the drivers, there is enough explanation on the Forum!
If you're curious, you'll see in your device manager in "port COM & LTP" a port whose name appeared is quite explicit!
4 Open Acer Tool!
IMPORTANT: If you're running Vista and Seven, do not forget to right click on the icon of acer tools and do "Run as administrator", if not crash!
5 You will see that you are logged in AMMS (connected (AMSS)), with "Browse" go get your bin, select "Select QCN File Manually" and START!
6 A window appeared, press "Yes"
7 And there does not touch anything, the flash is short, about 10 minutes or more depending on the PC!
...
8 A window is opened again, select the file I give you (desimlock.xml) And be open,,,
9 Do not worry your Flash will be a long shot, as if he walked over, wait (almost a minute!)
10 Do not touch anything now as you do not "Process Finished, You Can remove USB" Acer Tools!
11 Enjoy! Finished!
This method replaces fastboot and serves also unlocked
Small Tip: In another flash, Acer Tools has detected a former NAQ, and my re-simlocker Liquid, Think A1_QCN delete the directory at the root of C: (or save it elsewhere if you prefer!)
I hope this will help everyone!!
Remains for me to figure out how to manually send files to other AMSS and not having to use Acer Tools!

WINDOWS 8.1 => ANDROID PROCEDURE (thanks to Frontier)​
Required materials:
- A Teclast X98 Air 3G (obviously), battery sufficiently charged (recommended to be fully charged the battery before starting the process). The tablet will be running Windows 8.1 or in FastBoot mode
- The Android DnX BIOS (or Android BIOS) from here
- Tin last available (this season) Android ROM for the X98 Air 3G: X98_Air3G_(C6J6)-Android4.4.2-V1.10.7z
-The tools of the platform upgrade Intel (Intel Manufacturing Tools). These are available in two versions, the newer and older . Start with the newest and if do not work on your computer, install the older version. Only one version must be installed on your computer.
Upgrade Preparation tool (Intel Manufacturing Tools)
- Unzip the computer you use to convert (not tablet), the Android ROM given above.
- Unzip one of the two available sets of tools Intel Manufacturing Tools. Inside the folder, you will find some executables that run in the following order and always with administrator privileges:
iSocUSB-Driver-Setup-xxxexe: At some point during the installation, you will know that you have to connect the X98 with USB cable to the computer to install the NAND drivers. H connection is necessary otherwise you can install to see and shape the NAND memory of tablet.
IntelAndroidDrvSetupx.xxexe: We run this installer as an administrator with the tablet plugged in USB. This will install the ADB driver Intel, which appears in the Device Manager (Device Manager) for Windows. (See the picture Figure_1)
ManufacturingFlashTool_Setup_x.xxexe: This tool is used in the final planning "name" (branding) of the tablet and install the fastboot kernel. Install with administrator rights on the proposed application folder (hold down the name of the file for the next step).
- Upon completion of the installation of the Intel Manufacturing Tool, copy the file "CUSTOM_CONFIG.INI" into the folder that the tool was installed (the default is C: \ Program Files \ Intel \ Manufacturing Flash Tool).
The function is said to be installed and functional guest running on X98 Air 3G, host.
Once the installation of the guest operating, it becomes host to the tablet and just run it.
Not supported - for now - the simultaneous execution of Android & Windows.
Remove the microSD card that you probably have the tablet, before initiation.
From Windows host -> Android guest (conversion to Android tablet)
- Unzip the Android DnX BIOS directly into the Windows installation on X98 Air 3G.
- Run with administrative rights (from command line) flash.bat file inside the folder BIOS_X98_Air_3G_android. H process starts with the completion of the installation DnX BIOS displays the message "FPT Operation Passed".
- Turn off the tablet holding the POWER button for 10 seconds.
- Run Intel Manufacturing Tool as administrator.
- On the tablet, hold the VOL +, VOL- and POWER until you see the logo of the Teclast. The tablet will be "stuck" there, is perfectly normal. Connect the tablet to the USB port on your computer, so you will receive the following message: "Entering DnX mode. Waiting for fastboot command..."
- In the Device Manager of Windows (Device Manager), find the Android ADB Interface and right-click -> Properties (Properties).

3D GAMES FREEZES FIX (thanks to Akitoyo and acc007)​You can download the patch from here: patch for 3D games freezes
Then follow these steps:
1. Copy the update.zip to the root path of internal storage
2. Click OTA icon, then choose local update
3. Choose update.zip file then apply it, system will reboot automatically
4. There will be a new icon "Fastmode" on the desktop, choose it before launching large 3D games.
You must click it again if you reboot the tablet then play 3D games
If you haven't Teclast OTA app you can download it from here: Teclast update tool
If you want can find the apk attached to this post (fastmode.apk).
If you don't want use apk, use adb shell and then su to become root.Then launch these commands:
Code:
echo 400 >/sys/devices/pci0000:00/0000:00:02.0/drm/card0/gt_min_freq_mhz
echo 400 >/sys/devices/pci0000:00/0000:00:02.0/drm/card0/gt_max_freq_mhz
If you want a persistent fix, also after reboot you can create new file install-recovery-2.sh file and put it in ./etc folder with these istructions:
Code:
#!/system/bin/sh
echo 400 >/sys/class/drm/card0/gt_min_freq_mhz
echo 400 >/sys/class/drm/card0/gt_max_freq_mhz
Remember remount /system as rw and chmod this neely created file to 755. You can then execute it or restart to have it automatically started.

GOOGLE PLAY STORE FIX (thanks to Frontier and Hendrickson)​Anyone having issues with Google Play Store - this applies to both Air 3G with the latest 2.0.1 update (will post more information later) and Air II - please apply this fix.
Your OS should be rooted in order for this to work.
- Download the files from here.
- Follow this Hendrickson's Videotutorial
TECLAST X98 AIR 3G ANDROID KITKAT 4.4.4 ROM(OFFICIAL) v2.0.0 (thanks to Frontier)​Download the upgrade from here.
You also need the Intel Manufacturing Tools (get them from here).
After installing this ROM upgrade, you need to apply the Google Play store fix (links and instructions just above).
The procedure to install this ROM is described above in this post. Just ignore the part that describes how to flash the Android BIOS to the tablet, as it is not needed in this case.
This upgrade will erase all data in the internal flash storage (32GB), so make sure you have a recent backup for your applications.
This ROM is OTA safe, after installation the Teclast Software Updater will notify you for an updated ROM; install the update (it's quite small) so the final ROM version would be v2.0.1_20141505 (see Teclast_X98_Air_3G_Android_4_4_4.png).
Visible changes:
- Intel Firmware Updater Tool inside the Android system; you can use it to flash .bin files directly to the tablet within Android (dual-boot system).
- Google Play Store enhancements; I can install applications now that I couldn't with 4.4.2 release (e.g Google+, Paypal and various e-Banking apps).
- A (little) faster boot.
MICROPHONE GAIN FIX FOR ANDROID 4.4.4 (thanks to Frontier)​Here is the final version of the microphone gain fix.
Tests done:
- Voice recognition using Google Now and Google voice typing (even in Greek) works as good as on my OnePlus One with CM11s 44R
- GSM/3G voice calls are clear (I am using Wind GSM network) both with the built-in microphone and via Bluetooth headset (Samsung WEP210).
- Skype voice/video calls are clear, both with internal microphone and the Bluetooth headset.
Connect the tablet with USB cable to a PC with android debug bridge installed.
The tablet needs to have USB debugging enabled.
Open shell and cd to the location of new audio configuration file.
On a PC shell write:
adb root
adb remount
adb push AudioConfigurableDomains.xml /system/etc/parameter-framework/Settings/Audio
adb shell
In the adb shell write:
cd /system/etc/parameter-framework/Settings/Audio
chmod 644 AudioConfigurableDomains.xml
reboot
Done !
XPOSED ON 4.4.4 (thanks to majkel_94)​Ok guys, thanks to @jcespi2005 for Xposed ASUS mod which steer me to the correct solution in xda topic for Xposed
So here it is:
Downolad Xposed Installer (2.6.1 has been tested, modules working ok), install it but don't launch the app or install framework.
Download Root Browser, install and open it.
In root browser:
go to the /data/data/de.robv.android.xposed.installer/ and create folder "conf" (permissions rwxrwxrwx)
in folder "conf" create the file "jit_reset_offset" (permissions rw-r--r--)
Download Terminal Emulator, install and open it. Then:
type "su"
type "echo 0x98 > /data/data/de.robv.android.xposed.installer/conf/jit_reset_offset"
Reboot the tablet.
Open Xposed Installer, install framework, reboot.
Profit! You have working the latest Xposed and working KK Gravitybox!

ITALIAN TUTORIAL FOR UPDATE TO STOCK ROM FROM CUSTOM SELLER ROM (thanks to topdigamma.it)​topdigamma.it Tutorial

DUAL BOOT FAQ + HARDWARE AND LOW LEVEL FIXING​
FAQ
1)Q: While in Intel Manufacturing Tools and trying to flash, the progress bar is stuck at X%
The flash tool does not like funny characters ,should clear up some confusion as to why things aren't working.So before to flash please try removing the chinese characters from the file name. It screwed you up on something else having chinese in the name.
At 0%: Well, reconnect your device again, check your VID and PID values in settings, check if your drivers are properly installed, replace a cable if it is faulty, check that you're in DNX mode, basically, the flashing didn't even start.
If you have the right pid/vid from the device manager,unplug the device, close the app and restart it, select the flash.xml (should say ready to flash) then plug the device in while in DnX mode and it should begin.
At 5%: Mostly due to the fact that "Custom_config.ini" was not copied to the IMT directory, or there are some other programs that is blocking the progress, try changing a computer and flash again.
At 10 or 11%: Mostly due to wrong settings or parameters, check Device Manager in Windows for any missing drivers, check that the downloaded ROM is not damaged, or that the tablet is not already bricked. Also, this software is very sensitive to the USB port that it was first installed on, so try plugging it back to the same USB port that you plugged it during the install process. (Yes, you have to plug the device in during the install process, if you missed this out, uninstall all the drivers and redo the installation properly).Sometime help to try a different ROM, just to clarify you have copied the "custom_config" file to the Intel Manufacturer Tool folder right. It should get to 10% for about 5-10 seconds then make a disconnection sound and suddenly jump to 15% and continue.
At 89 or 90%: The files written at this stage are larger, so it might take a while longer, but if it is really stuck here, probably the USB cable is faulty. Replacing a cable and flashing again should solve the problem, or just simply leave the tablet and cables still (do not move them around) and try again.
If the flash freezes at 90% a solution could to be increase the timeout values in the program facturing flash tool.
At any other points: Might be due to faulty cables, or simply just try again!
2) Q: I flashed android bios, now I can not get in to droidboot mode by pressing Vol + and POWER. The tablet always gets into EFI shell command interface. I can only get to DnX mode by pressing VOL+ , VOL- and POWER. Any solutions?
A: Follow this steps valid for C6J6 and C8J7 model :
Open Intel manufacturing tools,then open file menu and go to the settings.
Put this value to SoC Devices: VID: 8087 PID:0A65
Put this value to Androird Device: VID: 8087 PID: 09EF
Click on apply and then on ok.
Disconnect the USB cable from the tablet and turn off your tablet (important)
Download the Android 4.4.4 ROM for C6J6 and C8J7 by supercows (link above)
Then in Intel Manufacturing Tool and go to the menu File -> Open. There, choose the folder of X98 Air 3G (C8J7.C6J6) lite 4Gb or 8GB and choice "flash.xml" for your device 4Gb or 8GB and open it.
Keep pressed VOL +, VOL- and POWER button until the tablet go to the dnx mode
Connect the USB cable and Intel Manufacturing Tool begins the process of flashing Android ROM.
Wait until the process is complete.
Disconnect the tablet from the USB and and turn off your tablet .
Connect the usb keyboard to the tablet and turn on your tablet, you could get shell command error again
Just type exit and you see the tablet go to the android version
When go to the android you must change your bios with ifwiupdate and you can flash dualboot bios or new android bios from first post
3) Q: I have problems getting into Android from the dual boot menu! Windows is okay.
A: If there are any problems getting into Android from the dual boot menu, change this option in the BIOS. Change "Boot Architecture" to "OS Boot Menu Only".
View attachment 3048901
4) Q: After shutting down the table in Windows, it takes very long before I can power it on again.
A: Turn off "Fast Startup" option in Windows Power Options. Another way is to navigate to "C:\Windows\System32", find "SlidetoShutDown.exe" and use that to shut down.
5) Q: The time in Android and Windows is not synchronised!
A: Go to "Run", type in "regedit", then navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation
Add in a new REG_DWORD, "RealTimeIsUniversal" and set its value to 1
6) Q: I plugged the tablet into the charger and it shows as charging but after a while I noticed that the battery percentage dropped!
A: Check the cable, it should be of good quality and as short as possible. Original teclast cable is good, not too long and thick enough. Best to use short cable of 5cm. This is due to high current and low voltage of the tablet.
7) Q: I'm on Android 4.4.2 and this tutorial needs me to upgrade to 4.4.4. How
A: Go to post #2, download the 4.4.4 ROM from there, start by following the tutorial from the line "WINDOWS 8.1 => ANDROID PROCEDURE (thanks to Frontier)" onwards all the way until you reach GOOGLE PLAY STORE FIX (thanks to Frontier). If you see the line "From Windows host -> Android guest (conversion to Android tablet)" in the tutorial, do not worry, because this process is used for both purposes, from Android to Android or Windows to Android, both are applicable.
8) Q: I flashed my tablet to dual boot OS already, but now I want to reinstall only one OS! How can I do it without having to reinstall everything?
A: If you want to reinstall Android only (leaving Windows unharmed):
One way is to flash just "system.img" through the Intel Manufacturing Tools (try this way first).
Download from here the zip named "ONLY FLASH system.img": http://1drv.ms/1s8dci8
Replace the "flash.xml" in your ROM folder with the one in this version.
Then flash as per normal using IMT.
This "flash.xml" will instruct the IMT to flash only the "system.img" file which is Android OS.
If that doesn't work, we will try flashing all components of the ROM without re-partitioning the whole eMMC,
Download from here the zip named "ONLY FLASH ANDROID PARTITIONS": http://1drv.ms/1s8dci8
Replace the "flash.xml" in your ROM folder with the one in this version.
Then flash as per normal using IMT.
If you want to reinstall Windows only (leaving Android unharmed):
Prepare your USB Drive with the Windows image.
Boot into Windows first, then restart and plug in the OTG cable, USB HUB, keyboard, and USB Drive.
Enter BIOS by pressing "ESC" key during boot and under the "Save and Exit" menu, scroll down to the "Boot Override" option, find the USB drive and select it to boot from it. The BIOS restart the tablet and will boot into the USB Drive so Windows install should start.
Remember the USB bootable stick must be created with Fat32 file system and GPT table partitioning.
9) Q: Help! My touchscreen is inverted!
A: (Thanks to @krisbliz):
Download the files from @krisbliz post here, and copy the files into C:\Windows
now run gpedit.msc
computer configuration
scripts (startup/shutdown)
startup
add
browse for reset driver.bat
10) Q: How to reinstall windows without reinstall android ? I cannot change the language and even updates from winddows update,every time when I put usb prepared and trying to install windows it working installation and after 65% shows installation error 0xc1440137 0x2000c and going back to previous instal (chinese) to windows
A: (Thanks to @mohamad_skiller):
Connect usb keyboard and usb windows instalition to your hub then
Enter BIOS by pressing "ESC" key during boot and under the "Save and Exit" menu, scroll down to the "Boot Override" option, find the USB drive and select it to boot from it.
The BIOS will boot into the USB Drive and Windows install should start.

When I plug in usb to install the IntelAndroidDrvSetup1.5.0.exe, in the boot menu I can see a Windows in the right center of screen and in the right top corner two small icons of android and windows which I can check. I dont see Android logo in the center of screen?
A: (Thanks to @jcespi2005):
Sounds you install windows on top of android partitions.So check what partitions do you have in windows partition manager...If you deleted the android ones, you'll need to start over starting installing android again.
In any case, make sure you've followed these steps correctly:

Yes,continue the installation and use drivers zip on the first page.Install the driver under gyroscope and run the registry file.Go into device manager,find the unknown device,install drivers and point manually to the drivers folder (it will install but fail to enable,this is normal) from here simply right click on the display,disable it and reenable, you can do the same with the 2 I/O devices for the orientation and accelerometer to fix the inverted screen rotation
15) Q: I partitioned my 32 GB SD card and formatted the smaller partition EXT4. Link2SD recognized the partition but it "fails to create MOUNT SCRIPT.
A: (Thanks to @kinhvanhoa ):
Probably you forgot to format your EXT4 partition on the SD CARD as "PRIMARY PARTITION."
Please make sure the EXT4 Partition which should be smaller than FAT32 partition, must be set as "PRIMARY" (FAT 32 as well).
Then, use LINK2SD on the Rooted Android, it works fine and allows apps to be moved to the EXT4 partition on the SD card.
16) Q: How can i change the intel turbo mode on to off? How can i enter in the bios mode? Only few games works, others freeze!.
A: (Thanks to @SUMMERBREEZE ):

From switched off press power button once to boot and keep holding vol up key pressed
18) Q: I have installed dualboot bios with a success. The icon of windows is not showed,why?
A: (Thanks to @grigoris_a):
If you don't see windows icon it means the USB is not bootable.Try getting into bios and see if the USB drive is detected and check the file system on your windows usb drive it should be FAT32. Often the problem is inside the bios, maybe is enabled the options the EFI format on the boot option, disabled it the icon of windows appears and then you can started the installation.
18) Q: I start from Windows 8.1 then I installed the Dual Boot Bios (No problem).
I restart to the bios, power down the tablet and power up again and use the Windows 8.1 again (without reinstall anything) with 60hz.

Then while its connected I power it up and shows the battery meter but the PC dont do anything so I cant use any program to flash android, any idea? I tried different cables and nothing
A: (Thanks to @Petepe10):
This is the normal way, do not know about dualboot though: Power up (vol up down power press) until screen shows dnx mode, and then connect cable. Flash starts automatically (provided pc is ready to flash of course)
19) Q: How to switch from an OS to another?
A: (Thanks to @BPM):
Power off the device and then press and hold vol+ and power until you see the bootmenu
20) Q: On the lockscreen in Windows the text in the lower right corner is chinese.

22) Q: On Windows is there any way to hibernate the tablet? I try to hibernate but doesnt works well,the tablets power off but you have to press power button for 10s to power it up again, and you start windows normally?
A: (Thanks to @seba2000):
Make a shortcut on your desktop to C:\Windows\System32\rundll32.exe PowrProf.dll, SetSuspendState Hibernate
and save it as "Hibernate" for instance.You can pin it to start as well.When you will run this shurtcut tablet will hibernate. Remember that after you will run this command (shortcut) you need to wait a bit before you will be able to switch on again (10-15 sec) . Do not try to switch on immediately - Windows needs time to dump all data from RAM to hard disk (need time to hibernate). In this tablet there is missing any led which show disk activity so you just need be patient.
After 10-15 sec you will be able to switch on by single power button press.
If you want add hibernate and sleep option in Windows, follow the vpx tutorial
23) Q:Why there is one hour difference between android and windows ?
A: (Thanks to @G3n3R4L):
Hit Start and type regedit.exe in the search box. Hit Enter and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\TimeZoneInformation. Right click anywhere in the right pane and hit New > DWORD (32-bit) Value. Name it RealTimeIsUniversal, then double click on it and give it a value of 1.
and done, time in windows is exactly the same as android under the correct time zone.
If you want to do these steps automatically you can use this reg file: abanglek's X98DualClockFix.zip
25) Q:Windows only reporting 1 battery cell, battery gets stuck at 7% for a few hours as mentioned previously here. Did anyone manage to fix the issue in Windows?
A: (Thanks to @grigoris_a):
1.Fully charge the tablet
2 Run cmd as admin and paste this command
powercfg-setdcvalueindex SCHEME_CURRENT SUB_BATTERY BATACTIONCRIT 0
3 Use the tablet until it shuts down
4 Charge the tablet without pushing power button until it charges fully.(let it overnight)
24) Q:Why I can't enter in fastboot mode?
A: (Thanks to @jcespi2005):
Just power off (press power off for 10 seconds), wait some time, 5 minutes, and press VOL+ VOL- and then power on until fastmode shows on the tablet. When you connect the tablet on fastmode, the Manufacturing tool just boot a droidmode image like this:
01/14/15 00:14:29.870 INFO : Port 0/0/4 #0: Booting droidboot image - SN : Baytrail00005B06
01/14/15 00:14:32.914 INFO : Port 0/0/4 #0: Booting to droidboot.img success - SN : Baytrail00005B06
25) Q: The brightness auto dimming up and down by itself. But This tablet no light sensor and cannot enable/disabled auto brightness.
A: (Thanks to @melvincz):
Go to the Intel Graphics settings utility (find it in the tray), choose Power section and disable all energy savings functionality. That will fix the auto-dimming issue.
That's all! ENJOY! If there are any questions feel free to post in the forum. Thanks!

FLASH BIOS WITH THE USB PROGRAMMER AND CLIP (thanks to Hendrickson)
You can follow the tutorial here:
Russian Tutorial
The clip took a few goes to connect and it finally do when you hear the windows beep beep that new hardware is detected. Flashed and verified and boots fine. Windows 8.1 installed the drivers itself. You don't need to install them.
Some tips, I did it with the battery connected and fully charged. I used the 25xx slot on the usb programmer and the clip #1 is the colored cable of the 8. #1 on the clip to the . connector on the winbond chip itself.
Flashing took around a minute its quick.
DISPLAY BRIGHTNESS THROTTLING (thanks to Petepe10)
I think I found a way to prevent that the display is heavily dimmed due to a thermal event. It is in thermal_throttle_config.xml in system/etc. My interpretation is that by the mod below the brightness reduction is not immediately to 40 percent but goes down in steps to 80 60 40. Wouldn't you agree? I have not found the trigger settings yet though. The xml is editable (I use total commander), reboot afterwards. I will test some more. Of course such thermal mods are not without risk, so be warned..

FIX HEADSET PROBLEM(thanks to Hendrickson )
If with music, it sounds like it's being played through a tunnel, or been compressed down to something like 8kbps. The main instrument tracks usually sound fine, but the vocal track is heavily muted and in some tracks practically inaudible; it's also tinny and a bit distorted.
It's not defective, it's a Iphone style jack, if you don't fully insert your 3.5 plug it will sound normal. Or use a headphone without a mic or a converter like this one: http://www.ebay.com/itm/301385140519?_trksid=p2060778.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

ANDROID => WINDOWS 8.1 PROCEDURE (thanks to Frontier)​
Required materials:
- A USB stick of 256MB (generally small), FAT32 configuration with label (label) WINPE (uppercase).
- A USB stick capacity of at least 8GB, formatted system NTFS. This will pass the installation files Windows 8.1.
- A USB hub to connect these two sticks in OTG cable X98 Air 3G. The hub would be good to have its own power supply.
- A Teclast X98 Air 3G (obviously), battery sufficiently charged (recommended to be fully charged the battery before you start the process).
Preparing USB sticks:
- Unzip the file WinPE_User_20140814.7z and copy all files directly on the root directory of the USB stick WINPE. See the picture Figure_1.
- Unzip the installation files for Windows 8.1 DVD into a folder named "images", which should be on the root directory of the USB stick of 8GB (with NTFS configuration). The Windows 8.1 version with Bing for X98 Air 3G is here (5 files total): Part1 , Part2 , Part3 , Part4 , Part5 . Inside the folder images, you need to have the files install.txt, install.wim, UnattendAudit.xml, UnattendUser.xml, WIMPART.TXT, Winre.wim. If you want to use your own image and make the USB stick with a tool (Rufus, etc), drivers for the Windows X98 Air 3G is here . If you use Rufus remember to use MBR for UEFI, not GPT!.
See the picture Figure_2
Preparation of material:
- X98 Air 3G enabled USB debugging in the settings.
- On the PC, will be available the tool adb (part of the platform SDK) and have installed the ADB drivers (adbdriver.com). The PC should recognize the X98 Air 3G before starting the procedure.
- It is recommended to install Intel Manufacturing Tools before turning the tablet on Windows tablet, in order to be able to restore it to operating condition if the procedure fails. These are available in two versions, the newer and older . Start with the newest and if do not work on your computer, install the older version. Only one version must be installed on your computer.
Upgrade Preparation tool (Intel Manufacturing Tools)
- Unzip the computer you use to convert (not tablet), the Android ROM given above.
- Unzip one of the two available sets of tools Intel Manufacturing Tools. Inside the folder, you will find some executables that run in the following order and always with administrator privileges:
iSocUSB-Driver-Setup-xxxexe: At some point during the installation, you will know that you have to connect the X98 with USB cable to the computer to install the NAND drivers. H connection is necessary otherwise you can install to see and shape the NAND memory of tablet.
IntelAndroidDrvSetupx.xxexe: We run this installer as an administrator with the tablet plugged in USB. This will install the ADB driver Intel, which appears in the Device Manager (Device Manager) for Windows.
ManufacturingFlashTool_Setup_x.xxexe: This tool is used in the final planning "name" (branding) of the tablet and install the fastboot kernel. Install with administrator rights on the proposed application folder (hold down the name of the file for the next step).
- Upon completion of the installation of the Intel Manufacturing Tool, copy the file "CUSTOM_CONFIG.INI" into the folder that the tool was installed (the default is C: \ Program Files \ Intel \ Manufacturing Flash Tool).
The function is said to be installed and the guest OS you are running on X98 Air 3G, host.
Once the installation of the guest operating, it is now host to the tablet and just run it.
Not supported - for now - the simultaneous execution of Android & Windows.
Remove the microSD card that you probably have the tablet, before initiation.
From Android host -> Windows guest (conversion to Windows tablet)
- Uncompress file BIOS_X98_Air_3G_android_to_windows.7z folder without spaces in the name (eg C: \ Temp). We should be inside the unzipped folder, a subfolder 'fpt-tools-package'.
- Connect the tablet to the PC and wait (in Windows) to recognize.
- If you have rooted your device,from a command prompt (with administrator rights), we give the following commands:
adb push c:\temp\fpt-tools-package data/local/tmp/
adb shell
cd data/local/tmp
chmod 0777 FPT
su
./FPT -F X98Air3G.bin
- If you have not rooted your device,from a command prompt (with administrator rights), we give the following commands:
adb push c:\temp\fpt-tools-package data/local/tmp/
adb root
adb shell
cd data/local/tmp
chmod 0777 FPT
./FPT -F X98Air3G.bin
- Once the execution of the last command and display the message "FPT Operation Passed", disable the tablet holding and hold POWER. See the picture Figure_3.
- Connect the two USB sticks in USB hub and the hub of the OTG port X98 Air 3G. Activating the X98 Air 3G with the POWER button, and automatically starts the installation process of Windows 8.1. The whole process takes a long time - and for this reason it is recommended that you fully charged the battery - and requires no user intervention. See the picture Figure_4.
If you do not automatically start the process, connect a USB keyboard to the hub, then reset the tablet (CTRL-ALT-DEL or off) and after doing reset, enter the UEFI BIOS by pressing DEL. At the boot menu, go to the Boot Override option and press ENTER on the USB stick (small in size) to do boot from there. See the picture Figure_5.
- When the message "WIMboot image deployment COMPLETE. Type EXIT from command prompt to restart or turn off the device." You can disconnect the USB hub and terminate the tablet. See the picture Figure_6.
The process of converting the X98 Air 3G in Windows tablet, complete!
After the Android to Windows conversion is it recommended first install the Gsensor, run the kxaccel-win8-x86-dbg-intel.exe that comes in the folder GSENSOR in the attached zip in and then execute the reg file.
Finally copy the TouchSetting.gt to C:\Windows\inf folder and reboot.
Everything should go smoothly now.
For the Italian friends I have prepared a simplified guide in Italian pdf.

LAST BIOS
Be very carefull, you could brick your tablet if you use a version of bios not in conformity with your tablet model.I take absolutely no responsibility for damage caused by the flash of the following bios.
C9J8 ( Warning, the tablet could became instable with random rebooting and even if you turned it off you have to wait 2 min to power it again)
mirek190 modified C9J8 bios
AIR II DUAL (compatible with C6J6)
grigoris_a AIR II DUAL bios
Disclaimer : these proceedings or files are provided "as are" and i'm not responsible for any lost (hardware / software )
I would also like to point out that these procedures have been tested on C6J6 only. For C8J7, there are some additional pointers along the way, do look out. All files in this tutorial are by default for C6J6, unless otherwise stated. Is highly recommend reading through the whole post first before touching your tablet to prevent errors, or worse, bricking the whole thing
Install dual boot(C6J6) - KEEPFISHES TUTORIAL (thanks to supercowz, mohamad_skiller, ro11er and Frontier)​
Please before you begin to read this tutorial is better to watch the Hendrickson's complete Tutorial video that show and explain all the needed steps for dual boot implementation.
The original post of keepfishes is here. in case he make some updates and it is not shown in this post
I found that the tutorial on the first page lacked detail and some steps were not shown clearly, so I made a new one that I think is easier to follow for newcomers! Will add screenshots soon.
Dual boot BIOS benefits:
Fixes 60Hz refresh rate for Windows 32 bit system
Probably on old bios there are low voltage settings for GPU that makes some problems with 3D games,after updated to dual bios no problems at all for many users
Drawbacks:
BIOS settings very little
No boot menu (so no easy way to reinstall Windows with a USB drive)
Time in Windows will mess up when using dual OS
The flashing process is roughly as such:

Many of us have different start points, some are coming from Android, some from Windows, but it does not matter. First thing is to flash with dual boot BIOS, which is most important.
WARNING: (Be very careful, this part may brick your device. After you get past here, you can practically do anything you want and there is almost no risk of bricking your device, so pay attention here!)
Get dual boot BIOS files here (both C6J6 and C8J7): http://pan.baidu.com/s/1sjK4Zbn
View attachment 3048864
Extract the BIOS "完美双系统BIOS.7z" and copy the contents to the tablet.
Note the filepath on the tablet, you will need it later.
1a) Flash BIOS from existing Android system
NOTE:
If your existing Android version is 4.4.4, you can use the "UpdateIFWI.apk" that was installed on the system to flash the BIOS.
If Android version is 4.4.2 on C6J6 and there is an "UpdateIFWI.apk" on it, there have been reports that it does not flash properly. (as reported by @ambrosio5)
Current advice is to update to 4.4.4 before proceeding. .For instructions on how to upgrade to 4.4.4 from other previous Android versions, see FAQ 7 below.
From the tablet itself, run “UpdateIFWI.apk”, select "Browser" and point it to the filepath of the BIOS named "X98Air3GDuala.bin''.
STOP: Make sure you have at least 50% battery and chose the correct file! If this fails, it might BRICK!
Now flash the BIOS.
1b) Flash BIOS from existing Windows system
From the tablet itself, RUN AS ADMIN the .bat file in the folder (the one with chinese words) provided.
View attachment 3048853
After you see the Green line “FPT Operation passed”, it’s good news.
Now reboot the system and you will be taken to the BIOS screen. Just igonore it and press power button for 10 seconds to turn it off.
2) Installing ANDROID first (must be done before Windows)
Now we need to FIRST install ANDROID. This step will wipe out your whole tablet (INCLUDING ALL PREVIOUS WINDOWS AND ANDROID PARTITIONS AND DATA)
ON ANOTHER PC (not tablet), download the Android 4.4.4 Lite ROM here: https://mega.co.nz/#!KI8T0bBb!Pv25K1Rh0MJvXSCYQEC8P8l1mbsZQRgG6q5-XezP_aI
OR
SUPERCOWZ ANDROID 4.4.4 C6J6 AND C7J8 ROM For Both: https://mega.co.nz/#!zVdgWJyS!Vh7zGqX6NcYgXrCf-5v_qmEReZXuicvGzw6h1u5OnGo
OR
USE ANY OTHER ROM YOU WISH
Download this modified "partition.tbl" file from the Chinese: http://pan.baidu.com/s/1qWnxc4G
Inside are two folders, the 5000 one is 5GB Android space, the 8000 one is 8GB Android space. I personally used 5GB, because I want to leave more space for Windows.
View attachment 3048857
Download and install Notepad++, we need to edit "partition.tbl" file below, the Notepad.exe and Wordpad.exe built in on Windows DOES NOT SAVE THE FILE CORRECTLY AND WILL NOT WORK!
Extract the contents of the ROM to a folder. You should see a "partition.tbl" file inside.
This file controls how the 32GB eMMC in the tablet will be partitioned in this step.
View attachment 3048867
Copy the "partition.tbl" file FROM the Chinese download (either 5000 or 8000) TO the Android ROM folder that you extracted. Replace the original "partition.tbl" file that came with the ROM.
Edit the "partition.tbl" file in the Android ROM folder, find the second last line, which is "add -b 5931048 -s 10240000 -t data -u 80868086-8086-8086-8086-000000000008 -l data -T 0 -P 0 /dev/block/mmcblk0"
and change the highlighted number to the value of user space you want in Android. The number is a multiple of 2048, so let's say if I want 500MB user space, I would have to multiply 500MB x 2048 = 1024000 and input "1024000".
View attachment 3048872
I tried 300MB but it was too small, I think 500MB would be good if you're planning to use more Windows. Save the file!
Credits to FRONTIER for Android ROM flashing instructions (I made a number of changes):
The tools of the platform upgrade Intel (Intel Manufacturing Tools). These are available in two versions, the newer and older . Start with the newest and if do not work on your computer, install the older version. Only one version must be installed on your computer.
- Unzip the downloaded Intel Manufacturing Tools. Inside the folder, you will find some executables. RUN THEM IN THE FOLLOWING ORDER WITH ADMIN RIGHTS:
iSocUSB-Driver-Setup-xxxexe: During the installation, DO NOT PLUG IN YOUR TABLET. Near the end of the install, there will be a text asking saying that you need to plug in tablet and power cycle to complete installation. ONLY PLUG IN YOUR TABLET THEN, and do as the instruction says. After you're done, click Finish. After install, you should see Intel SOC device in your device manager.
IntelAndroidDrvSetupx.xxexe: Plug in your tablet, and MAKE SURE that your computer RECOGNISES your tablet. You will see unknown ADB device if you plug in the tablet. Now run this program as ADMIN, this will install the ADB driver for the unknown device. In device manager, if it still shows unknown device after install, manually update the driver in device manager and browse to the install directory of the driver, it will then install the driver from there.
ManufacturingFlashTool_Setup_x.xxexe: Install with ADMIN rights, this will install the Flash tool with the Lightning icon, which is the GUI interface we use to flash our tablet.
Copy the file "CUSTOM_CONFIG.INI" from the downloaded folder into the install folder of IMT (the default is C: \ Program Files \ Intel \ Manufacturing Flash Tool).
Remove the microSD card from tablet.
Run Intel Manufacturing Tools (the one with Lightning icon), In the Settings menu, change the VID and PID values to this, then click apply and OK:
If you're using Windows XP, your VID and PID values may be different to the ones shown. Check the instructions on Post #2 on how to get the values.
View attachment 3051023
Close the IMT application and launch it again. Go to the menu File -> Open. There, choose the folder of ROM you want to flash, find the file "flash.xml" and open it. The "flash.xml" file which tells IMT how to flash the tablet's eMMC.
(IF YOU ARE USING SUPERCOWZ Android 4.4.4 C6J6 and C7J8 ROM, here are his instructions, :
flash with ManufacturingFlashTool
for C6J6 open in ManufacturingFlashTool :
flashC6J6-4GB.xml or flashC6J6-8GB.xml
for C8J7 open in ManufacturingFlashTool :
flashC8J7-4GB.xml or flashC8J7-8GB.xml
this last action dedicate 4 or 8 gb of rom space for Android and you can install windows in 18.5 or22.5 gb free rom space.
Then reinstall Android rom as before (open manufacture flash tools and select flash.xml)
After install android rom you can install windows as before (using bootable windows usb disk and select 18.5 or 22.5gb rom free))
-----------------------------------------------------------------------------------------------------------------
8) Turn off the tablet holding the POWER button for 10 seconds.
- Run Intel Manufacturing Tool as administrator.
- On the tablet, hold the VOL +, VOL- and POWER until you see the "Entering DnX mode. Waiting for fastboot command..."
Click image for larger version
View attachment 3048873
- Connect the USB cable to the computer and flashing will start.
- After progress bar is green and 100%, hold down power button for 10 seconds to turn off tablet.
If the progress bar turns red, take note of the percentage that it stopped at, and refer to FAQ 1 below.

View attachment 3048876
After finishing these steps, Android is now installed on the tablet, and if you power it up, you can see the dual boot menu with the Android logo.
Click image for larger version
View attachment 3048880
If you're happy with ANDROID only without Windows, you can stop here and just boot into Android! You can go on to do the Google play store fix and others...
3) Installing Windows
If you plug in your USB drive via the OTG cable and boot up, you will see the boot menu with an Android icon and a small Windows icon. (If you don't see the boot menu at all, shut down the tablet and press Vol + and Power button until the boot menu appears).
This small Windows icon is the only way to get the BIOS to boot into your USB drive to install Windows. This dual boot BIOS has no boot menu, and in the BIOS there is no option to select to boot from USB, so this is the only way to boot to a USB drive that I know of so far...
(If you already have a USB stick prepared, skip this section in BLUE)
Preparing your Windows USB Stick:
You can install Windows via the traditional method which involves the GUI (in which case you will need an OTG HUB to plug in the USB Drive and mouse together) OR you can use a downloaded wimboot image (no need for HUB and mouse, just a thumbdrive will do).
Whatever the case, make sure your USB Drive is formatted as FAT32! Very important!
I used this wimboot image that automatically uses WinPE to get through the whole install process automatically without needing a single mouse click, which also has all the drivers and everything installed and working properly:
Waiting for repost on mega...
Link: http://pan.baidu.com/s/1hqIfAle
password: zhec
Extract the downloaded files and then copy all the contents into the root of the USB Drive. NO NEED FOR RUFUS!
If you are not using the above images, and use other Windows ISO or images as found in Page 1 or if you want to make your own images, you will need this software RUFUS:https://rufus.akeo.ie/
Follow tutorial here on creating the USB Drive: http://www.techverse.net/how-to-create-bootable-usb-flash-drive-install-windows-8-1/
Remember to use MBR for UEFI, not GPT!
If your Windows doesn't come with drivers, you can download them from here and install them:
https://mega.co.nz/#!tJdHCIAT!agSun8Wa1tOx_3tL8YMuS19j1i5wWG2WUJPprmTbTCs
Here also a Windows 8.1 PRO version with drivers and English/French language pack (thanks to supercowz):
Win 8.1 PRO with driver and eng/fr language pack
Plug in the USB drive via OTG cable or HUB, and choose the small Windows icon until it turns blue, then hit the grey button below and Windows installation should start.
If it asks you for which partition to install to, you will see a great many partitions there (due to Android), don't worry, it is normal. Typically you will install Windows to the largest available partition. (Unless you set the Android user space partition in the "partition.tbl" file previously to be huge)
DO NOT TOUCH ANY OF THE ANDROID PARTITIONS, IT WILL DESTROY THE ANDROID SYSTEM!
Everything should go smoothly from here and you can remove your OTG cable and USB drive once Windows starts asking for your User Name.
4) Final Steps
One last step. Thanks to Android, we have to hide the Android partitions from Windows, because when we open "This PC", Windows will attempt to mount all the partitions and cause the whole thing to hang.
So, go to control panel, administrative tools, computer management, then Storage, then for each of the RAW partitions that belong to Android, right click and choose "change drive letters" and choose "remove", then OK. Repeat for the rest of the partitions, leaving the C: drive alone. DO NOT DELETE ANY PARTITIONS OR ANDROID WILL NOT WORK!
Note: For people who only want to install Windows and don't want Android but still want the dual boot BIOS (due to the 60Hz refresh rate), I have tried it and it works. What you need to do is to follow this tutorial exactly, but REPLACE STEP 2 WITH THE ONE BELOW:
STEP 2) This step will wipe out your whole tablet (INCLUDING ALL PREVIOUS WINDOWS AND ANDROID PARTITIONS AND DATA)
Yes, even though we are not installing Android, we need this step still:
ON ANOTHER PC (not tablet), download the Android 4.4.4 Lite ROM here: https://mega.co.nz/#!KI8T0bBb!Pv25K1Rh0MJvXSCYQEC8P8l1mbsZQRgG6q5-XezP_aI
OR
USE ANY OTHER DOWNLOADED ROM AS YOU WISH
Download this modified "partition.tbl" file from the Chinese: http://pan.baidu.com/s/1qWnxc4G
Download and install Notepad++, we need to edit "partition.tbl" file below, the Notepad.exe and Wordpad.exe built in on Windows DOES NOT SAVE THE FILE CORRECTLY AND WILL NOT WORK!
Extract the contents of the ROM to a folder. You should see a "partition.tbl" file inside.
This file controls how the 32GB eMMC in the tablet will be partitioned in this step.
Copy the "partition.tbl" file FROM the Chinese download from the 5000M folder TO the Android ROM folder that you extracted. Replace the original "partition.tbl" file that came with the ROM. Edit the "partition.tbl" file in the Android ROM folder, find the second last line, which is "add -b 5931048 -s 10240000 -t data -u 80868086-8086-8086-8086-000000000008 -l data -T 0 -P 0 /dev/block/mmcblk0"
and change the highlighted number to 2048. Save the file!
Open "flash.xml" with Notepad++.
DELETE this chunk:
<code_group name="system">
<file TYPE="system">
<name>system.img</name>
<version>eng.yankendi</version>
</file>
</code_group>
AND THIS CHUNK BELOW:
<command>
<string>fastboot flash system $system_file</string>
<timeout>420000</timeout>
<retry>2</retry>
<description>Flashing 'system' image.</description>
<mandatory>1</mandatory>
</command>
Then save the file.
Follow the post on the FIRST PAGE HERE, scroll down and start from this part onwards “WINDOWS 8.1 => ANDROID PROCEDURE (thanks to Frontier))” until the end (stop at "GOOGLE PLAY STORE FIX (thanks to Frontier)"). READ BELOW FIRST:
Because we have already done certain steps, we can ignore some parts:
PARTS TO IGNORE:
Under the "Required materials" section
IGNORE: “- The Android DnX BIOS (or Android BIOS) from here “
If you wish, you can use Android 4.4.4 lite ROM in place of the 4.4.2 ROM as proposed here.
Under the "From Windows host -> Android guest (conversion to Android tablet)" section
IGNORE all these: (because we have already flashed BIOS)
- Unzip the Android DnX BIOS directly into the Windows installation on X98 Air 3G.
- Run with administrative rights (from command line) flash.bat file inside the folder BIOS_X98_Air_3G_android. H process starts with the completion of the installation DnX BIOS displays the message "FPT Operation Passed".
After finishing the steps, you can power it up, you can see the dual boot menu option with the Android logo and a very small Windows icon. Continue and follow STEP 3 in the guide. You can partition your 32GB eMMC in the Windows setup to remove all previously created Android partitions and make it into one large Windows partition to install Windows.

Maybe you should copy some post about Air 3G from X98 Air thread?

Nice english instructions for rooting, Win->Android, Android->Win, removal of bloatware etc. would be nice. Everyone can use google translate to navigate official chinese forums but you will get funny translations like "Brush Wizard software". If instructions are unclear and they leave space for interpretation mistakes can happen. Worst case scenario is bricked device.

After using windows and Android I still have the same gpu issues. I also looked in the log and at the end of every crashlog (in android) I see a dev_prive->gpu_error, which is a call from the kernel. (I saw some code on the internet about this) So, my intel Atom chip is bad. Going to return it and ask for a replacement.
The error seems to only happen when I use an app that uses opengl 3.0 (and a LOT of games use that!).
Also about the touchscreen, there seems to be a major problem with the driver in linux. Since I guess they cross-compiled the driver, I am guessing they made the same mistake in both android(linux) and windows.
How did I verify this? Well I used a goodix android application which had some demo app and I saw that the moments the touchscreen gets refreshed are not constant. Let me explain.
When I slide my finger over the touchscreen with a constant speed this happens to my tablets:
This is what my "old and smooth" tablet does(every dot is a touchscreen refresh): .---------.---------.---------.---------.---------.---------.---------.---------. (this is a constant refresh)
This is what my X98 Air 3G does: .--------.--.---------.-.-------.------.-------.-.-----.-----.-.-----.------.----.----.---------.-------.----. (not constant at all)
So the times the touchscreen gets refreshed is not constant. The result is that especially scrolling doesn't work that smooth.
And on top of that, the response time is extremely slow. I am guessing that the driver puts the touchscreen into sleep mode after every single touch, which is stupid. The response (as stated in the goodix GT9271 datasheet) is <200ms. Lets say it's about 100ms, do you know how slow that is??? If your mouse would only refresh every 10th of a second, it would be extremely slow!!!
If I didn't have gpu issues and the touchscreen issue would be corrected, this tablet would be superb, but that is not the case of course.
I am going to contact Teclast if they want my help in enhancing the touchscreen driver. (I am an embedded software engineer specialized in C/C++/C# code)
Also, I might be able to make simple C# app that does most of the work when you want to flash your tablet from android to windows. (this could also be done with a very simple windows batch script)

Hi Jote, sorry again for my bad english.
The biggest problem is that most of the information and instructions on how to root, how to change OS,etc.. come from the Chinese manufacturer's forum.
As written before your help in any way will be really appreciated! This is true also about the translation from chinese to the english language.
I ordered this tablet because I think it has enormous potential enclosed in a shell of very small dimensions, if we combine our knowledge to bridge the gap of the Chinese language I think we have great satisfaction with it.
I will try to add link to files for rooting, for change the OS and get other resources asap.

My tablet hasn't arrived yet but I tried to prepare everything.
I'm unable to browse the official forum. I've tried on several days but forums are just working extremely slow. When i try to browse directly through Google Translate I get "Proxy server to access restrictions ". I'll try again someday to find proper threads but right now i'm useless.

So the touch screen is going into sleep states very quickly? I noticed compared to the Onda v975w that it was much slower. I have the X98 3G air now and I have gotten use to it. But it would be nicer if it was how you pointed out.
I have disabled Allow the computer to turn off this device to save power, under power management on the Goodix Touch HID in device manager.

Yes, that it what I am claiming right now based on the information I know and what I have experienced at this point.
I attached the zip containing the datasheet of the goodix GT9271 touchscreen controller. (it's the touchscreen controller inside our tablet if I can believe the log)
The zip also contains an android app from goodix. You can select demo in the menu and then test the touchscreen in various ways. Give it a try
Disabling the "Allow the computer to turn off this device to save power" isn't going to work I think. It can only be done in the driver and I am not sure if it's even supported. It's standard USB stuff, but the GT9271 is connected via I2C. This is a Inter-IC Connection to other chips (IC's) of smartphones/tablets like touchscreen controllers, temperature sensors, accelerometers, gyroscopes etc.
I use it a lot in embedded software engineering and I2C is a very common connection in embedded applications. USB is very heavy for small systems, but I2C does require "special code" to get it up and running.
This will give you a better idea of what an I2C connection is capable of(example of RK3288):

Sorry for all the information
Edit: I contacted Teclast and said I'd like to offer them help for free. Let's hope they accept my free help. (if they are smart...)

Someone can check if is it true?

I've set-up an easy to follow guide (in Greek) for Android -> Windows flashing.
The link is here and the translated (in English) link is here.
The procedure of flashing from Windows -> Android is here (English translation is here).
Feel free to copy it and post it here in order to help others.

I have a question about the screen, namely, whether at you vertically (then best seen) is the difference between the left and right sides of the LCD to the distance from the frame (the black space)? In my left is approximately 2 mm and 1 mm from the right. Such a little thing but unobtrusive I hope you understand what I mean.
Next case. Has anyone tried to install on Android Xposed? For me, after the installation of almost every application resets the tablet .
How can I boost speaker volume in this tablet?

[GUIDE]Huawei P8 Lite Downgrade/Unlock Bootloader/Root(5.0 and 6.0)/ Enable Gyroscope

Disclaimer:
I am not responsible for what you do to your device, I tested these things for myself and posted it from my own experience, if you point the finger at me for whatever happens to your device, I will laugh at you.
HOWEVER, I am willing to help as long as it is asked kindly, and provided me with enough information.
Requirements:
Huawei P8 Lite ALE-L21 (DUAL-SIM)
5.0 Firmware of choice
Unlocked bootloader
Patience
Correct drivers
SD card of atleast 8 GB
Drivers: Install these before even starting!
Minimal ADB Fastboot drivers
Huawei HiSuite
Kingoroot Windows
TWRP 3.0.2.0 Kirin variant
Preparing environment: Making sure no admin priveledge is necessary
Install all drivers mentioned above in their standard directories, don't change anything.
Go to the following path:
Code:
For x64 OS:
C:\Program Files (x86)\Minimal ADB and Fastboot
For x86_32 OS:
C:\Program Files\Minimal ADB and Fastboot
Copy these files:
Code:
adb.exe
AdbWinApi.dll
AdbWinUsbApi.dll
fastboot.exe
And paste them on the desktop, in a folder called "rootingtools" so you're easily able to find it.
Then, go to your phone and enable USB debugging mode by going to
settings - about phone - press Build number 7 times
settings - developer options - USB debugging
Copy the content of "TWRP-3.0.0-2_P8-lite_KIRIN_variant.zip" and paste it into the "rootingtools" folder.
Backing up: Even though the unlocking process is not going to wipe your data, atleast it didn't for me, make SURE you have everything that you need backed up from the phone's internal memory.
Backing up your SD card wouldn't hurt neither.
First things first, unlock your bootloader!
I used this: https://emui.huawei.com/en/plugin.php?id=unlock&mod=detail
What you do is: fill in everything correctly and get the number at the end. It should be something in the words of:
Code:
Your unlocking password is: XXXX XXXX XXXX XXXX
(X resembles numbers, 16 numbers in total)
Copy the 16 numbers and go to the "rootingtools" folder on your desktop.
Hold the SHIFT key and right click inside the folder, then press "open command window here"
Now take your phone, power it off and power it on by holding volume DOWN and POWER.
You will get a white screen that says something like fastboot, and an android logo.
Plug your phone into the PC via USB cable.
In the command window write:
Code:
fastboot.exe oem unlock UNLOCKKEY
Where UNLOCKKEY represents the key you just copied, right clicking pastes the key in the command window.
It should return finished, so now your phone should be unlocked!
If you look at the screen, there will be text beneath the green Android logo saying "unlocked".
In this case, the operation has succeeded and you can go to the next step, else you can try again or post a reply.
Now write:
Code:
fastboot.exe reboot
Now the phone will boot up like normal.
Close the command window.
Android 5.0:
If your android version right now is Android 5.0, and you actually WANT to root 5.0 or anything below 6.0 you can proceed with this step, if you have 6.0 or want to root 6.0, skip this step.
Since your android version is 5.0 you're blessed!
You can easily root, but before proceeding you might want to make a backup
Make sure you have about 8GB of free storage either on an SD card or internal memory first.
Connect your phone to your PC in the booted-up state where you can see the homescreen, making sure that USB debugging is enabled.
Shift + right click inside the rootingtools folder to open a command window and write:
Code:
adb.exe reboot-bootloader
Your phone will reboot into the bootloader, a white screen with a green Android logo that says "unlocked" beneath it.
Now on the command window write:
Code:
fastboot.exe flash recovery recovery.img
Wait for it to finish and pull out the USB cable so it is NOT attached.
Power off the device by holding the power button, and power up by pressing volume UP + POWER.
Keep holding volume up until you see the Team Win logo.
Just slide the slider to the right.
Now go to "backup" and check every partition available.
In "name" you write:
Code:
MainBackupURTD
Then, go to the "options" tab and enable compression.
Go back to the "backup" tab and press "select storage".
From here you can choose where to back your data up, whether it be the internal storage or external SD card.
Press OK and swipe the slider to the right to start backing up.
Plug your phone in to make sure it doesn't power off during backing up, this process takes a while and you should let it do its thing.
When done, press "reboot system", your phone will reboot.
Let it fully start up.
Then, run Kingoroot on your PC.
Meanwhile, download the "SuperSU" app from the Play store.
Press the big "ROOT" button in Kingoroot and press "cancel" on every app your phone tries to install.
That way you will not install Kingoroot but SuperSU.
It will say "succeeded".
Now you can go on your phone and open the SuperSU app.
It will ask for an upgrade, press OK and go further with the normal installation (not the TWRP/CWM installation).
Let it do its thing and restart your phone.
Install any root checker and see if you're rooted!
Android 6.0:
Firmware version B188 or higher, below B524/B535 (excluding B524/B535):Upgrade firmware to this one: LINK (Link fixed)
Installation instructions: place file to the "dload" folder in your SD card or internal storage, then go to settings - updates - menu - local update and press the update.zip.
Then, follow the guide reported here: http://rootmygalaxy.net/root-huawei-p8-lite-android-marshmallow-6-0-update/
Enabling Gyro sensor (rooted android 6.0, B524/B535 firmware only! ( sorry :[ ) ):
Download attached file.
Put attached file to SD card.
Open ES file explorer, swipe to the right, enable root browser and click the R/W tab, then set /system as RW.
Then copy the attached file.
Paste the attached file in /system/etc/permissions
Press the search button and search for "gyro" without quotation marks.
Long press the only file that's there - menu and press properties.
Then change the permissions to 644, it should look like this O represents off, X represents on;
X X O
X O O
X O O
Set UID is off, Set GID is off, Sticky bit is off.
Reboot phone and download "Sensor box for Android" on the Play store and enjoy your gyroscope!
Now you can use Google Cardboard, though you have to install the APK...
You can watch 360 videos on youtube too.

Hiya, will the gyro hack work on a L02 B130 Android 5.0 as i can't get an update to 6.0 here in New Zealand?

unable to get unlock code
The Huawei ID used to apply for the unlock code has not been used on the device for more than 14 days.

@sevenaudio
As far as I know, the hack is for android 6.0 but there should be no problem in trying it out
It's just that it only worked for me on these FW
@DrLittle
I think Huawei has this policy of using your Huawei ID for 2 weeks (2 weeks online time) before you can unlock it
You could try sending them an email!

Hi, can you pinpoint what you were trying to do when it got stuck?
As in, what were you trying to flash.
And what is your phone model?
