[x98 plus 3G A6C9] 3G network not working - Teclast X98 Air 3G

Hello,
I'm from germany and got my tab a few days ago and most is working fine.
The only thing ist the 3G network, I can't get it working, neither in Android(build V1.03_20160307) nor in Windows(Version 1511 Build 10586.104.
In android the tab is asking for the SIM PIN and is displaying the provider info and the signal bars with a small exclamation mark.
In windows 10 he also displays the network provider but network is deactivated
Regards

Error: Kies does not support Mini 2

I'm receiving the below error when connecting my Mini 2 to my PC:
'This device is not supported by Kies 2.0.'
This is obviously not the case. I have tried to re-install Kies many times. Not a driver error as I can use it like an external drive in Windows Explorer.
mobile: Galaxy Mini 2 (S6500D), stock rom, usb debugging enabled (tried with disabled as well)
pc: Windows 8 Enterprise (does not need Media Feature Pack)
Kies: v2.5.2.13021_10
I have already checked tonns of forums but no solution found so far.
Thank you in advance for your ideas.

It is.
Windows XP, Windows Vista, Windows 7, Windows 8**
** Windows 8 includes Windows Media Player.
If using Kies with Windows 8 operating systems, please be advised that currently only Samsung Android OS and BADA OS based mobile devices are supported

Never used Kies before. Or it's because USB Cable ?

Tried. Same issue.
it's because CSC. i don't know a english post of how to solve this, but here i put a spanish tutorial translated:
Megatutorial: Change CSC (Country Specific Code)
Hello friends, I bring you good news, is on the CSC. It is very important because Megatutorial.
The first thing I have to say is, when the Stock Rom flashearon and went to Kies, noted that they came this message: "The device does not support software upgrade of Kies travez" I asked Samsung about it and they said it is a program error, but they were wrong.
Navigating today, I discovered that when you leave that message, you can never upgrade by Kies, but today, I found the solution. The just try, and I have regained the ability to upgrade by Kies.
What is CSC?
The CSC, for its acronym in English (Country Specific Code) refers to code each terminal, belongs to this region, to have one that does not correspond to our phone, it automatically stops inactualizable.
Navigating discovered how to change it, I'll put it in red to make it attractive.
procedure:
1. - First dial * # 272 * (not dial anything else, not pressed the call button)
2. - Following this put your IMEI (You can see it by dialing * # 06 #) and finally I put #
3. - I stay like this: * # 272 * 53259623505748 #
4. - Once done will get a menu with several CSC choosing whichever of Spain or location. You can search the Internet for the CSC. (Mine was PHE), this can also be seen when viewing the Stock ROM file includes code.
5. - They give the Install button, and the phone will restart, but when that happens, it automatically makes a Wipe will erase all applications.
NOTE: We agree that to flash the Stock Rom, starts in another language, then change it in-law, beginning in SPANISH. So if it works and check Kies, and I no longer went out that Messaging
1. - First dial * # 272 * (not dial anything else, not pressed the call button)

this code does not work on my device

I did everything until Step 4. Connected the phone to the PC without internet on both, and this error happens http://snag.gy/SYnU2.jpg and if i try again with internet on in PC, it downloads something ( http://snag.gy/MGPVd.jpg ) inside the Chinese software and the Launcher Error ( http://snag.gy/ps4P7.jpg ) shows up.
I tried it many times and tried with names Lumia 520, 920 and 1520 but nothing works.
I think its some problem with my drivers though my pc detects it and i can even register and unregister it through Developer Tool provided by Microsoft.

Hello, sorry for bad english language I'm italian and I'm 14.
You have to click CTRL+R, write "intl.cpl", go to "Administrative" and click "Change System Locale", select "Chinese, Simplified, China", and once applied click Restart now.
After reboot it should work, if you can't do it here's a video that explains everything. (It's in italian)

[Q&A] [ROM] HUAWEI Ascend W1-U00 | v1.00

Q&A for [ROM] HUAWEI Ascend W1-U00 | v1.00
Some developers prefer that questions remain separate from their main development thread to help keep things organized. Placing your question within this thread will increase its chances of being answered by a member of the community or by the developer. Thanks for understanding and for helping to keep XDA neat and tidy! :smile:
DerSchorsch1 said:
It seems that in this video it's described, how the sdcard-problem can be permanently solved, so that we don't have to put the card out and in after a shutdown. Is this right?
Can this be implemented in the rom?
I don't understand the steps to do in the video. I can only recognize that i has something to do with visual studio. Can someone describe it more detailed?

You did notice that this is an emulated device I hope? Rules for an emulator and for a live device are usually different.. just because a fix works in the emulator it doesn't have to work with the device.. and as far as I'm aware it doesn't.

Thanks for the ROM dev work!

Is there an option I missed during install?

I need help
Hello, I also use the HUAWEI Ascend W1 I come from China, I would like to know about the method of making the rom, and I open the app file will get a mbn file and do not know how to proceed, and I'm very interested in this, you can explain under it? (My English is not very good, but please forgive me use google) If you teach me, would be extremely grateful!
Hello,
thanks WojtasXda for the effort!

It will be possible to install the rom from Osx or linux?
Registry tweaks from russian forum (4pda)
Here, guys, tweaks for our HUAWEI W1.
Go to \Windows\Packages\RegistryFiles and place OEMSettings.reg here.
First bootup will be ~2 minites.
Tweak list:
-Camera sound on/off in sound settings;
-Wi-Fi connection sound on/off;
-3g/Wi-Fi arrows in status bar switched on;
-Activated PfD (don't install program);
-Jailbreak(interop unlock,capabilities unlock)
-Can be installed hacked appx's from wp-seven
-SDK registered
-Search button opens google
-Any app can be placed to camera's button (e.g. OneShot)
-Now you have Nokia Lumia 920 (doesn't really work).
To make your phone 'NL920', you must mount in regedit 'SYSTEM' and install 2nd (zip). After that, you can easily install all Nokia Exclusives via SysApp Pusher (also, more apps in store!).
I think you've got a typo in the OEMSettings.reg file (inside the same-named archive), on one of the tweaks that's supposed to give file system via USB:
Code:
[HKEY_LOCAL_MACHINE\SYSTEM\controlset001\services\MtpSvn]
should be
Code:
[HKEY_LOCAL_MACHINE\SYSTEM\controlset001\services\MtpSvc]
unless it's supposed to control the Media Transfer Protocol Subversion
Will this work with Huawei Ascend W1-U00 from Globe PH plan?
Hi.
My phone was given to me by my mother who received it with her Globe (a Philippine mobile network service provider) postpaid plan (which unusually uses prepaid services). I've been frustrated with this phone's storage becoming full very easily even though I only have very few apps (except for Spider-Man Unlimited which downloaded a 200-MB DLC) installed and I don't put any files in the phone storage. Since Huawei seemingly abandoned their Windows phones, there's no hope of us getting any update so we're stuck with the stock WP8 update 1. Will this custom ROM work with this particular W1-U00? Does anyone know where I can get a stock ROM for this particular phone?
Name: Windows Phone
Model: HUAWEI W1-U00
Software: Windows Phone 8.0
Screen Resolution: 480x800
OS version: 8.0.10211.204
Firmware revision number: 1030.5614.29400.20500
Hardware revision number: HD1U8835M Ver.B

I have the U34 and I've not been able to flash it. I always get the same cookie error in QPST, and handshake failure error in WP8 Flash Tool.
I hope you will be able to find the way to flash the U34.
You need install Windows 7, Use Qemu or Vmware. Drivers from package with QPST doesnt works in W8.

That's not true at all. QPST works perfectly fine on Windows 8. The only issue is if you're running a x64 OS, in which case you need to run the QPST programs as admin.

Problems with Flashing
Hello!
At First thanks for the good work. I will donate it, if i getting it work for me.
I got some Problems with flashing.
1) With Flash Tool:
Diag Setting is on, Phone is resetted and with the Flashtool i get the "Firmware Handshake Fail"-Error.
2) With QPST i can get into Download Mode (Qualcomm ... 9008) but then it shows me a "Cookie not received"-Error.
I tried the Flashtool in Downloadmode but that doesnt recognize my device.
My PC-Config:
Windows 7 Ultimate 64-Bit
Intel i5 Notebook
My Handy-FW:
Huawei W1-U00 Simlock Free
OS Version: 8.10.14203.306 Developer Preview
Thank you very much!
Edit:
I got the Problem. It only works for me without Diag Settings and only with QPST.
The folder from the Repair Bootloader was: W1-U00 Repair bootloader/flashing/
and i only copied the "flashing" folder. Now no "Cookie"-Error.
Hope this helps someone....
Step 2 error
I finish step 1. Flash custom ROM with QPST (Windows 8.1 x64).
Phone in mass-storage mode (all disk available).
Qualcomm MMC Storage USB Device present in Device manager.
When run WP8CRUU get error: Cannot open device "Qualcomm MMC Storage USB Device" Error 5 .

Problem solved:
With phone connected as mass storage reinstall Qualcomm USB drivers!

Error 109 on WP8CRUU.exe
Does v1.10 require v1.00 flashed first? I'm getting an error 109 (Cannot open device Qualcomm MMC Storage USB Device) when I run WP8CRUU.exe. My phone's (W1-U00) already in mass storage mode.
Now, I'm getting an error 5 (Cannot open device Qualcomm MMC Storage USB Device).
Can anyone please help me with this? I was able to flash the ROM with mass storage mode capability and set my phone to mass storage mode. Now, I can't flash the custom ROM because of this error. I don't think I missed anything. I'm running this on a Windows 7 Ultimate 64-bit. I didn't install MS Visual Studio 2013 since it requires Windows 8.1. I did install the Qualcomm USB drivers, simpleio, and QPST. I have MS Visual C++ 2005, 2008, and 2012 (all 32-bit) installed.
Arhy's workaround didn't work for me, by the way.
personal settings/data
Hi everybody,
is there a possibility to flash the rom and still keeping the wp8 personal settings (like contacts, certificates, calendar arrangements,...)
Or is it possible to do a "backup" of personal data in wp8 and do restore in wp8.1 ?
Any hints welcome.
BTW
Thanks for the rom and the hard work...

As far as is can see you just can backup fotos, messages, and IE-settings.
(no contacts, calender-information, certificates,...)
Is there another way to get at least my contacts from WP8 to WP8.1?
An additional question:
Is it possible to get back to WP8 after flashing the WP8.1 rom?
Any hints welcome

You can edit hw_default.xml on cust for that, you can show 4.5G if you want it to.
But doesn't means that is true.
You can e in 4G zone but no LTE.
Example my icon shows 4Glte because is on 4G network with LTE.
Huawe have a prop written wrong, i fixed and stars to show like this.
I can't remember for sure but i think is this
persist.volte_enabled_by_hw=1

Hi, I don't know if this information is still useful for you.
I have a P20 pro running on EMUI 8.1 and the device no longer displays "LTE+" anymore after I changed my device model from L04(Canada) to L09(Europe).
This method works for me.
For the Mobile Country Code(MCC) you can find it in this link. Open the link then try to find your country.
en.wikipedia.org/wiki/Mobile_country_code
For example, I'm in Canada and my Mobile Country Code(MCC) is 302.
So, I will input something like this in my terminal
settings put system hw_show_lte "302;260"
then reboot the device.
Some findings:
1. After I changed MCC to 302, the device doesn't display "LTE+" anymore.
2. I tried 310(US) and my device displays "4G+" icon, not “LTE” or "LTE+"(Maybe every country is different).

Yes, you have to put the quotes. I don't know what 260 means. I just follow the instruction form DarkJoker360.

settings put system hw_show_lte "302;260" Then I changed mcccodeofcountry to the actual number

Tablet connect to Android auto head unit.

Hi , how are you guys , I hope everything is fine!
Is it possible for a tablet connect to Sync 3 as client device?
I just bought a china non branded tablet "Voyo i8 max" and I'm try to connect it to my Sync3.... and fail with nothing happened when I connect it.
For this Sync 3 HU , I'm pretty sure it is work well with Android auto , because I had ever connect it successfully to my HTC U Ultra.
The information of this tablet:
1. Android 7.1.1 ( I think it is AOSP)
2. CPU : Mediatek Helio X20
3. 4G ram
4. 64G flash
5. 4G LTE supported and able to dial phone to talk
That is what I tried for this tablet:
1. install Google play , service ....etc.(almost all I know apps from google frame)
2. install AA V3.4.582534 , V2.9xxx , V2.6(?)xxx
3. several USB cable were tried.
4. set tablet usb mode to data-transfer , charge , MTP ......etc.
5. root it and change build.prop from table to phone.
6. set tablet enable developer option and set usb as debug mode.
One thing very special is I follow this:
developer.android.com/training/auto/testing/
