Hello
I bought a Teclast X98 Air II . It says it comes with android installed. Does anyone knows any way to install windows 8.1 on it?
I managed to obtain win8.1 from the teclast forum, the firmware for this specific Air II.
But there was nothing mentioned regarding the bios part. Any ideea?
I will upload 8.1 firmware soon on some share.
Any help? Anyone else with an Air II?
Thanks
Subscribed to this topic as I will also receive my air II very soon and want to install Windows onto it.

done
good news:
1. received my teclast x98 air II
2. managed to install and fully run windows 8.1 bing edition.
will post in the short future a full tutorial that will include rooting, installing, activation
will also provide every software / files needed.
does anyone recommend any file sharing service?
Try firedrive.com - as far as i remember you get 50gb for fairly fast storage.
And most of all - thanks for your help, it would be great if you could write a tutorial here.

Subscribed too, I'm also very interested in how you managed to install windows. I ordered my x98 air 2 a couple of days ago. I will be going to install windows as soon as I get it.
bios brick
can someone send me a right bios for the teclast x98 air 2? i only find x98 air or x98 3g.
i want the bios for android or for windows or both, i take all i can get.
now my tablet cant startup, without a bios. i need a new for external flash.
sorry for my bad english, im from germany, i hope u can understand me
edit:
if i get the bios data i can install any other windows not only the bing version. but with the brick i cant do anything, and i cant find any bios for windows and cant find for android...
i get the hardware driver from another(german) side for display and so on, i just only need the bios data ...
Thanks. I'll be watching this thread as well.
I am seeing conflicting information on whether this tablet has GPS capabilities or not. I would love to have someone confirm what it actually has. If this doesn't have GPS then I'd be curious to know if there are any alternatives.
I am too new to the forum to post links but you can search on YouTube for videos from user HONGKONGEEK where they have posted an Unboxing video for this version of the tablet.
that's awesome, mkdk!!
Instead of the Win8.1 Bing version, is there any chance of flashing a Pro version instead?
I bought this tablet with the high resolution with the intention of installing Win 8.1 so I don't have a pay a premium price for a nicer screen.
Can't wait until instructions are released!
This will be my first post of many .
Awesome work mkdk, did you follow instructions for the first air or the 3g version?
Bought the 3g version for my girlfriend and the android version works well for her. No luck for me with my air II since google play wont work, so now im looking to install windows instead .
Looking forward to the guide!

yes u can u only need the chines bios for windows, than u flash it and u can bootup all windows installations u want: xp, vista, win7, win8, win8.1.
u only need the bios file, than flash, than boot up windows from stick on a 3-usb-hub (u need mouse, keyboard and win-install-stick)
after installing u can take the chines hardware drivers for touchpad, sound and so on and its ready and u dont need anymore the mouse, keyboard or stick. than u can have a winxp tablet with touch, but it isnt usefull, may better win8.1 and all is easy or u can take win8.1 pro, what u want.
only need this .................. bios file... :crying:
bios

AFAIK you can install Pro if you integrate the Teclast drivers into the image (use Wintoolkit & Rufus).

Thanks for the bios nandika6!
So how do you go about his, are the instructions from teclast x98 air 3g also valid for the air 2 when it comes to flashing the bios?
FIY i did the latest OTA from teclast on android and google play/services still does not seem to work so i guess android is a big nono, atleast for now.

best man! you made my day! thanks!
*** I would count these instructions as obsolete due to some gripes with drivers, please refer to JonMichaels instructions in a later post. I will however leave this post if someone needs it as reference or has problems with the other method ***
Ok, so i managed to install both windows 10 32-bit and windows 8.1 pro N 32-bit!
I would not recommend windows 10 since i had a couple of issues there, but win 8.1 works very well with some small gripes that we might solve together!
First a small guide .
Guide to install windows 8.1
For the most part i could use the instructions in the thread for teclast x98 air 3G. I did however not use Teclasts bing version of windows, i created a win 8.1 pro iso instead and embedded the drivers.
Step 1: prepare the image
I only used one usb-drive for my installation (not the WINPE way as described here ), at first i tried with a 32gb drive but it did not work, a 8gb kingston memory did however work. So you might have to test a couple of drives to get it to work. Checkout this post to grab Wintoolkit and Rufus, you will use wintoolkit to inject drivers and refus to prepare a bootable drive.
Once you have these tools you will need to find a windows 8.1 pro 32-bit image to use, i took mine from dreamspark (for students), but you should be able to get one from microsoft directly. Do however mind that i could not bypass the "insert key stage" for a trial version, i had to get a key for this. If you want a fully working win 8.1 pro you will need a key when you install the OS (I don´t know where they are the cheapest, perhaps G2A).
Download the drivers for Teclast x98 air 3G and extract them to a folder. Start up wintoolkit and press all-in-one-integrator to start the embedding process. Browse and select the image that you downloaded earlier. Select the drivers tab and press the Add selection in the menu bar, select the folder with the teclast x98 air 3g drivers, then press start and select a place for the modified image to be storded. Once this is completed (takes some time) close the all-in-one-integrator and select ISO maker, select a place to create a new iso and name it something like "win8.1".
Insert the drive you want to use as a boot-device for your newly created image. Go ahead and start up Rufus and select the drive you want to use. Under partition schema make sure that the GPT partition schema is selected, also make sure that you format it in FAT32. Press the little CD symbol and select the image that you created earlier and press start (this will also take a while depending on the drives writing capabilites). If all goes well you will now have a bootabel usb-drive with win 8.1 pro that the tablet will accept.
Step 2: Flash the bios with the one given to us by nandika6
The next step is to flash the bios to the version that nandika6 gave us. Follow the instructions in this post and use the commands for "if you have not rooted your device".
I had some gotchas with this, simply downloading the adb driver did not work as i could not detect the device in the command prompt. This was solved when i ran the intel manufacturing tools and got the correct usb drivers for the tablet. I did however not do anything with these tools ( look into this if you dont want to keep windows forever, said something about that, i will however not switch back to the buggy Android).
Step 2: Install windows
Once the flash is complete you will have to shut down the tablet and insert the boot-drive. If you end up in the EFI-Shell this will probably be due to the usb-drive not being compatable (this happend to me), in that case repeat step one with another drive. It could also be because the drive is not first in the boot priority, connect a keyboard and pres ESC when booting to get to bios, select the drive and reboot.
If all goes well you will only need to connect a usb-drive since the drivers for touch will work on the fly, if not you will need a mouse and keyboard. The drivers can be manually installed via the device manager (alot of warnings here if this is the case, solve them all by inserting a usb-drive with the drivers folder from earlier).
When this is done you will hopefully have a working istallation of windows on the tablet!
Some gripes
Screen rotation does not work for me at the moment. I solved this in windwos 10 with a file that comes with the drives, this did however make the tablet rotate the wrong way. I will look into this and post a solution if i can, please feel free to inform us if you find a solution first .
The camera is not working for me right now, will look into this.
The tablet will automatically adjust screen brightness even if you turn this of in the power management. This is caused by the intel driver that overrides this, open the intel controll panel and disable active dimming here to solve the issue.
@Thundermeister: helpful guide. Maybe your gripes can be fixed using an updated driver (from the Air II Windows image).
Did you by any chance look into making a WIMBoot image instead of a normal install?

Thanks for the tips mtr33, will take a look at that image (if i can find it ). A WIMboot looks very nice, the space saving would be real nice to have. Right now the install takes up around 8 gb on the tablet. I also found some Onda users having the same problem with the rotation, gonna take a look at that image as well, the tablets seem to use the same sensor for orientation.
For all of you having problems with Google Play store, I have a fix here : http://forum.xda-developers.com/showthread.php?p=56779242
This works on both 4.4.2 and 4.4.4 ROMs.

How to install Windows 8.1 on a Teclast X98 Air II Android Tablet:
You will need:
2 USB Memory sticks - 1 small (no more than 8 GB) & 1 large (6 GB or more)
1 USB Hub (preferably USB2 & powered)
1. Go to this web address 1drv.ms/1EQ1X5v (Microsoft Onedrive) & Download all the files to your computer.
2. Plug the small memory stick into your computer & format it (Right Click on the drive's icon then scroll down & Click on Format) using FAT32 File System & set the Volume Label to WINPE (all caps).
3. Decompress WinPE_User_20140814.rar to your computer & copy the files to the root directory of the memory stick. Eject & remove the stick.
4. Plug the larger USB memory stick into your computer & format it using NTFS File System.
5. Decompress X98_Air_II_Windows_20141022.part1.rar to your computer & copy to the root of the 2nd memory stick. Eject & remove it from your computer.
5. On your Android tablet, go to Settings, Developer Options, & check USB Debugging (then Ok).
6. Decompress X98-Air II-WIN8 bios.rar to your computer.
7. Connect one end of the USB data cable to your computer & the other end to your tablet (close all running programs on your computer & make sure the tablet has at least a 50% charge).
8. Open the X98-Air II-WIN8 bios folder & Right Click on X98-Air II-WIN8 bios.bat & Click on Run As Administrator (enter password if prompted).
9. Type 1 & press enter to install the USB driver (Install driver dialog box should pop up, click Next to finish the installation).
10. Type 2 & press enter to Root the tablet (wait for it to finish).
11. Type 4 & press enter to flash the tablet's BIOS (do NOT disturb tablet or do anything on your computer while it is flashing!)
12. If there are no error messages, press the tablet's power key for 10 seconds to turn it off & pull out the data cable.
13. Plug both USB memory sticks into the USB Hub (& plug it in to the wall, if powered) then plug the Hub into the USB adapter (that came with the tablet). Plug the other end of the adapter into the tablet's micro-USB port.
14. Turn on your tablet & leave it alone until it is done installing windows (should take several minutes).
15. Hold the power button for 10 seconds to turn it off, then turn it back on.
16. After Windows 8.1 loads, change it to your desired language (it will be in Chinese) & enjoy!
hey! i just got teclast x98 air 3g from my university and apparently its was only on android only and it bios was locked. so i flashed the latest bios to unlock dual boot option and i succeeded. Now it has dual boot option but only shows android. can any body please guide me thoroughly on how to install windows 10 in it also with android still being available as dual option. its c8j7 model of x98 3g air.
please help i really want to use windows 10 on this with android. Any help will be highly appreciated.
Thanxx
You should just have to download Windows 10 (32 bit edition) from Microsoft and install it on a USB Drive (GPT + Fat32).
Just be sure you have empty space on the "hard drive" and start the X98 and press ESCape key to go to the boot menu and choose your USB Drive.
If Windows have enough space it will install itself and create the 2 partition it need, that's it !

Windows 10 Upgrade problem "We couldn't update the system reserved partition"..
I have installed an original copy of Windows 8.1 Pro in my Teclast X98 Air 3G and try to upgrade to Windows 10 using the Windows Update feature, but everytime I try it, it returns the error "We couldn't update the system reserved partition". I increased the System Reserved partition size to 500MB as Windows 10 need, but no luck.
Anyone have a solution to that problem?

Just start a "clean Install/Upgrade" from a USB drive. If your Windows 8.1 is registered legally with the X98 Windows 10 will activate itself onb Microsoft server after the Installation, no need to enter any serial since after the first registration all other registration are done based on the hardware of the X98. :cyclops:
N.B.:Be sure to use the 32 bit version of Win 10.
Thanks my friend, i'll give it a try. Do you know if camera works?
Both camera work on my C5J6 after clean install Win 10 Th2 and the right driver.
Hi,
I did a clean Windows 10 install and of course, the Boot to Android app in Windows has gone.
How can I get it back? I tried copy this app from a brand new x98 (wifi version, not 3G) but it did not work.
Many thanks.
On techtablets in the download section is the original switcher.
Search for "Teclast Windows To Android Switcher".
Just a general remark:
The new Win10 update from microsoft wich is rolling out as of today solves a lot of issues on the x98 tablets.
For example networking issues on mobile plans are solved, battery indicator fixed, no more flashing of notification shade, overall response much faster. And that's just at first glance.
This looks pretty cool!

Thanks ! it is workable when remove SD card . they could upgrade to 586 successful .
What about the orientation problem with the new update!
Orientation is all messed up again and the reg file from the drivers pack does not work any more!
No problems on both x98s. Came from original bing 8.1, upgraded to 10 and now to the new build without issues. C5j6 and c8j6.
On c8j6 cameras not working
3g, wifi, screen rotation, gps all ok
on c5j6 all is working: camera, gps, 3g, wifi, screen rotation, sd card etc.

I'm having the same issue. Had to lock the screen into the correct position. Have not found a solution. I think I will need to mess around with the registry to fix it.
I tried the update twice on my dual with no success. I had removed the SD as I'd been warned about it : the first time it shut down, maybe because the battery was low (despite of the power supply being plugged). When I rebooted it said I needed 14Gb to start the update, so I plugged a OTG USB Key and gave its path. Then it started and downloaded the update again, and failed (I don't know when). Now I'm confused about how to do this update.

You need the SD and USB drives removed for it to update. Delete stuff to make room or go the reinstall route.
I still have issues with touch screen rotation after the update...
Thank you for your help. My windows partition is almost mint, I just installed the Window 10 pro from this forum, office, Kodi. There is 3gb of free space, afaik I can't do much better. I'll check wether there is to clean files from windows update, and I'll try again without SD/USB
Did you delete the previous Windows installs?
Old versions of Windows will be left on the drive in case you want to revert back and they take up a lot of space.
You can do drive clean and use the advanced or admin only option and check how much is in the old windows file.
I don't have my tablet with me or I could give you the exact path
With a 32 Gb partition you should have close to 16 Gb free... at least... I'm sporting windows 10 November update...
It failed again and again, I give up.
Questions to those who succeeded :
- how much free space did you have?
- did you have Windows 10 normal or PRO?

my teclast is original partitioned and the windows partition is 37.5GB in size.
at the moment I have over 16GB free space, this is with libreoffice, adobe première elements, utorrent and several small tools installed. all these were also installed before the november update.
I am using windows 10 home as official upgrade from 8.1bing
Hi,
I'm wondering: On Win10 (pre1511) my x98 (c5j6) always tries to install a new graphics driver - but always fails. ALso, I can manually start this process in the device manager, same result.
What else can I do?
Best wishes

Hey, I succeeded to get it to work on air II. I had to do the following:
- change the battery mode to never turn screen / power off when plugged
- cleaned c: drive - deleted system files (including windows updates to force redownload)
- ran the update and this time it worked
The other alternative is download the Microsoft Media Creation tool, create a new USB installation media (include updates), and then do a "clean" install (reinstall windows 10). This will install windows 10 with the 1151 build.
It's worth it as it now allows us to use the SD card to install apps!
Thank you for your feedback.
As I can't get more free space, I'll wait the next W10 big update. At this time, I'll format all partitions to get more space for windows, by reducing the android one.
I tried the media creation tool but not chosing a fresh install, only update. Failed.

same here on a C9J8 ?
would love to have a working camera for video calls. Any way to fix that?
oh, and the CPU seems limited to 1.6GHz?
Last night I installed an update for Windows 10 version 1511 (KB3124200) and everthing seems to be smoother. The only problem I have is that the battery stays at 7% for a long time. Tried to completely discharge it but doesn't work...
