    Today I received the Teclast X98 Plus A5C8. When I started the Android, and changed the language, after that my son open the developer option, suddenly the gyro become abnormal and doesn’t function properly. We rebooted the tablet, after that tablet failed to boot to Android, and I keep getting error message:

    ‘Unfortunately, System UI has stopped.’

    The tablet cannot boot further, stuck on that error message.

    The Windows 10 works fine.

    In this condition, is there a way to reset the Android? Or probably re-flash the Android ROM without affecting the Windows 10 ?

    I cannot go into the system setting to do factory reset because Android stuck.

    Thanks!

    Looks like the error was caused by the Input and Drawing features in the Developer Options. So better not to touch those settings.

    After troubleshooting for days, I finally fixed my tablet from that System UI error, using adb command to wipe the Android cache : fastboot -w

     

    Step 1 : Install the following Intel driver so the tablet can be detected by Windows.

    I read that in Linux, Intel driver is not necessary.

    1) First, install iSocUSB-Driver-Setup-1.2.0.exe file;
    2) install IntelAndroidDrvSetup1.5.0.exe file;
    3) Finally, install PhoneFlashTool_5.3.2.0_win32.exe file;

    Most probably PhoneFlashTool is not required if we only need to run adb command, but I did install those 3 files.

    Those files can be downloaded from Teclast Download section by entering the table model number, which is in this case is A5C8:

    http://www.teclast.com/tools/pad/showtools.php

    Or direct link to Baidu Cloud:

    http://pan.baidu.com/s/1KWEPw

    This is the package file name for those files is : Android5.1系统升级工具.rar

    I’ve uploaded those driver and flash tool to Mega as well:

    https://mega.nz/#!eIk0yDJJ!UMfpStN_95pSGJc3YC83mGI99UmET53NbSMix0WuKus

     

    Turn ON the tablet, and select boot to Android. The ‘Unfortunately, System UI has stopped.’ error will appear when the booting is done, now connect the tablet to PC using USB cable, and let it be detected by Windows. Start the PhoneFlashTool, the tablet should be shown on the PhoneFlashTool device list, as shown on the attached screenshot. Sometime I have to reboot the tablet a few times till it get detected by the PhoneFlashTool. Then switch off the tablet.

     

    Step 2 : Set the OS Image ID in BIOS to Android.

    Press the Volume + button together with the Power button, until the BIOS menu is shown.

    Set the OS Image ID in BIOS to Android, and then Save Changes and Reset.

    Turn ON the tablet, and select boot to Android. The ‘Unfortunately, System UI has stopped.’ error will appear when the booting is done, and then shutdown  the tablet.

     

    Step 3 : Open Command Window for adb command.

    Download the Android ROM from Teclast, same download link as above.

    I also uploaded the same file here on Mega:

    https://mega.nz/#!yRtUFbqS!xYL3vAkBqjHOGiyLlHU1lHtIjE8lJPaLDkjYZpZ5NWk

    Extract the package and go to the ‘Android 固件’ folder using Windows Explorer. Press ‘Shift’ button on the keyboard and then click the mouse right button on empty space on Windows Explorer, then select ‘Open command window here’.

    Connect the tablet to PC using USB cable, and turn ON the tablet, and select boot to Android. The ‘Unfortunately, System UI has stopped.’ error will appear when the booting is done, and then shutdown  the tablet, while USB still connected. The tablet then will be automatically started to go to charging mode.

    On command window, run the following command: adb reboot bootloader

    Tablet will be rebooted to Fastboot Mode as shown in the attached picture. In Fastboot Mode, On command window, run the following command:

    fastboot -w

    When the process is done, reboot the tablet. On my case, the The ‘Unfortunately, System UI has stopped.’ error didn’t appear anymore, and Android boot normally. You may change back the OS Image ID in BIOS, back to Windows. If not Windows boot will show error, and Windows will automatically change the Image ID in BIOS to Windows.

     

    Good luck!

    Thank you so much Bram Prebedi for your instruction for fixing ‘Unfortunately, System UI has stopped.’ I got my Teclast X98 Plus 3G (A6C9) last month and when switching around Developer Options, suddenly I got myself stuck in ‘Unfortunately, System UI has stopped.’ error message. I browsed through all over the net for the solution but all in vain. Finally I found your solution and downloaded the Android ROM and Drivers for Teclast X98 Plus 3G (A6C9). At the end I was successful in fixing the error following your steps. I’m really grateful to you.

    Thank You very much Bram Pribadi. It worked on Teclast x98 plus 3G (A6C9) model too. Great!! I also got in to the same problem by messing with the drawing and input options in Developer Options section. Better to leave them untouched.

    By the way, Does any type of touch pens work in Teclast x98 Plus tablets? Passive or Active? Like to do some note taking on it.

    Thanks!
