i've seen numerous posts about this all over the place and couldn't find a fix anywhere
after providing logs to jcsullins he managed to solve my issue and now have a fully working TP again
heres the thread i created over at rootzwiki http://rootzwiki.com/topic/37804-battery-question-mark-issue/
and heres the link to the irc post for jcsullins to guide people through it
only created this here as i know a lot don't go on rootzwiki but many have this issue
http://rootzwiki.com/topic/36658-tpdebrick-v01/page__st__310#entry1068329
hopefully this will help someone out and resurrect your thought to be dead TP
I noticed the links in this post doesn't really lead you to the debrick guide, so I am writing this.
P.S. I am ONLY reporting my experience as is to my HP Touchpad 16GB running CM-tenderloin. I am not in any way responsible for developing this method nor am I responsible for any extra damage that might happen to your already problematic Touchpad. Good luck, and research is your best friend.
I got this question mark battery problem as well and after doing some research I thought my HP Touchpad was gone for good. Then I saw this post and after reading it it inspired me to try the tpdebrick made my jcsullins. And... it worked and my touchpad is back to normal (with everything data intact as well, to my surprise!). My problem was similar to described by other posts in this forum: the touchpad was discharged until it turned off, and then it was left that way for a long time, and when I tried to charge again, it would first give me a flashing home button and then the battery with a question mark after a long time of charging. No matter how long I charged the problem persist, and the device refuses to go into recovery mode no matter what I do. WebOS is unable to detect the device as well, but the PC was able to recognize it as Palm or UQSB something something something (I forgot what it was). After this problem I did not do any battery change or hardware changes. Just me, the question mark battery, and the tpdebrick buigde by jcsullins.
So if you have this problem and absolutely cannot get into the recovery mode, give tpdebrick a try. I used tpdebrick-v004 by jcsullins: rootzwiki.com/topic/38786-tpdebrick-v004
Follow through the steps in that post and it should be okay. But, in case anyone needs it, this is all the steps I did:
0) While my screen was displaying the question mark battery, I pressed Power + Home + Vol Up + Vol Down for 30 seconds while USB plugged into PC to make sure everything turns off (i.e. black screen, no flashing home button). This step may or may not be necessary since part of the debrick process you need to do Power + Home + Vol Down, and it will most likely do the same thing. But just in case.
1) downloaded Ubuntu 12.04 32bit, downloaded webOS 3.0.5 doctor (this was in zip format, and I had to change it to .jar extension), and downloaded tpdebrick-v004.zip from the link above. You can download webOS doctor and tpdebrick in Ubuntu so that you can follow the instruction as written without any trouble, but I did it in my Windows and I fetched it from the Windows storage in Ubuntu. Whichever is easier for you.
2) Downloaded Universal USB Installer and made a bootable USB of Ubuntu. Followed instruction here: ubuntu.com/download/help/create-a-usb-stick-on-windows
3. Boot from USB and run Ubuntu OS
4. Found and moved the tpdebrick.zip and webos jar into the Ubuntu OS Downloads folder
5. Followed steps 14 to 23 from the debrick instruction by JC above. (Basically run terminal, unzip tpdebrick-v004.zip, and hold power + home + vol down for 30 seconds, and run script, and then run "sudo ./tpdebrick XX" where XX = size of your touchpad)
6. Wait patiently for 5 - 10 minutes, and then it says All Done. By this point, my HP touchpad rebooted back to the original state. If this does not happen for you, then you might need to keep researching! Good luck!
NOTE: After the process, my touchpad rebooted back into CM, and I noticed the battery was fully charged. So, obviously there was no problem with the battery nor the charging process. My problem must be due to miscommunication with the battery status.
Thanks
Thanks, it helped me a lot!

I was able to fix my touchpad with this rootzwiki guide above. My touchpad had JB installed, after a battery drain it was completly dead. I was able to charge it by cutting down an old USB cable and charging the battery alone (touchpad had to be opened).
FYI (Tried ubuntu 12.04.2 in 2 different machines, the tpdebrick only worked on my alienware on the Dell with 1GB of ram it did not worked. The alienware has 2GB of RAM.)
The battery took almost 50% charge, then tried booting it up and nothing (only got question mark).
Theres a small button inside the unit in the charging module, I pressed it, and the unit turned off (it was the only way I could get it to shut down.
Did the debrick process, after that the touchpad would not charg via the USB port and only via the touchstone, so I did the ACMEUninstaller to remove android and it's good as new again. The problem for me was caused by the JB android installed. I had no problems when it had ICS.
Followed the instructions in the link from the first post. And it works!
Was skeptical as instructions seems very complex, but I thought I got nothing to lose. In summary, it was straight forward and you just need to:
1. Download Ubuntu 12.04 LTS and burn the iso to a CD/DVD.
2. Boot up your PC with the Ubuntu Installation CD.
3. Select Try Ubuntu rather than Install.
4. Follow the listed steps/instructions. PS: If you see a "space" for the terminal command, there is a "space" required when you key in the terminal command. And when the script is running, its working, even though you see nothing on the touchpad screen. When "All Done", the touchpad simply rebooted by itself, and ran through the usual boot-up sequence.
Good luck.
Its fixed!!!! Thanks!!!

Glad it worked for you. I knew the directions said to use Ubuntu 12.04 which is still available so it is good to know 14.04 which is
the current Long term release of Ubuntu works as well.
I'm sorry, but it was this one that I used

Thanks for the info..I obviously misread your post.
Questionmark of Death on TP
First problem I ran into, couldn't find a working link for the webos doctor, after an hour of searching, came across a link but xda won't let me post since I don't have 10 posts.
w w w . adbtoolkit.com /rooting/devices/hp/tenderloin/webOS-Doctor/wifi/#.VGYTS9YghCW
Next issue, when it told me to hold my power+vol down+home button down, it would time out with some error( I think it said qdl not found something like that). Tried a few times, then tried a samsung cable for my phone instead of the original touchpad cable, and that worked. Thanks to the guy at rootzwiki for the information.
Does anyone have information on where to find this information now? rootzwiki seems to have deleted it.

It's not deleted. You have to log into rootzwiki from the error screen, and the link will load.
Unfortunately if you don't have an account, you can't register any longer for one (I couldn't get the registration process to work).
Luckily, there is the Internet Archive. I can't post a link, so change the 2 "URL" with HTTP in the below:

[Video+Guide] HP TouchPad Root Certificate fix for WebOS cloud services
https://www.youtube.com/watch?v=L63RiBXhQCY
How and when to Use the WebOS Doctor(Important):
https://www.youtube.com/watch?v=wFAIJiS8g4o
Q: What’s the WebOS Doctor and when should I use it?
The WebOS Doctor is a program that has two main functions for HP TouchPad users. It can either update your version of WebOS or fix problems with a damaged WebOS by completely reinstalling it. If WebOS no longer boots or apps and preware have stopped working correctly, then you will need to resinstall WebOS with the Doctor. A failed or interrupted attempt at changing the partition sizes with WebOS preware app Tailor may cause these problems. To check what version of WebOS is currently installed go to Launcher(Up Arrow)/Settings/Device Info/ Version
Note: If run the WebOS doctor after March, 15 ,2015. then you will need to bypass the WebOS activation with the instructions here
Note(Important): You MUST uninstall Android before running the WebOS doctor. Failing to remove Android before running the Doctor can result in the process becoming stuck at 8-12% and potentially bricking the device. If you are currently stuck visit the thread below for information about fixing the problem. If you’re unable to use the tablet at all follow the instructions in Jcsullins TPDebrick thread.
The Official Fix your TouchPad ( 8-12% stopped, No SD, Opps reformat, $&^#[email protected]&# crap....) thread.(Rootzwiki)
The Official Fix your TouchPad ( 8-12% stopped, No SD, Opps reformat, $&^#[email protected]&# crap....) thread.(CM)
TPDebrick v004 - Jcsullins dedicated thread for fixing Bricked TouchPads:
Note(Important): Running the Doctor will completely wipe all personal information, applications and preware from the TouchPad. Media like music and movies will not be affected. However I would recommend backing up your important files to PC, before running the Doctor.
Note(Important): In order to install apps from the WebOS store you will need to get the Root Certificate fix for WebOS cloud services.
[Video+Guide] HP TouchPad Root Certificate fix for WebOS cloud services
How to run the WebOS Doctor:
1) Install Java
-Java must be installed in order for the TouchPad to communicate with your PC.
2) You MUST completely uninstall Android from the HP TouchPad before running the WebOS doctor. Remove Android by running the ACMEUinstaller2. Watch the following video for full uninstall instructions.
How to Uninstall Android or CyanogenMod on the HP TouchPad (All versions)
3) Download the latest 3.0.5 WebOS doctor application to your PC. If upgrading you can check your current version from WebOS by going to Launcher(Up Arrow)/Settings/Device Info/ Version.
WebOS Doctor 3.0.5 Official Link
4) Put the tablet into WebOS recovery mode by doing the following:
-In WebOS Reboot the device by going to Launcher(Up Arrow)/Settings/Device Info/ select “Reset options” choose restart.
-As soon as the screen goes dark hold down the volume up button until you enter WebOS Recovery mode. Note the large USB symbol that should be on the screen. If you miss it just reboot again and hold down the Volume up button right away. Once in WebOS recovery mode connect your USB cable to the PC.
5) Now you’re ready to run the WebOS Doctor app by clicking on the .jar file you downloaded in the previous step. Be sure that your tablet is fully charged and connected with the USB cable before starting this process. Running out of power or interrupting this process in anyway could brick your HP TouchPad. Please be careful and fully read the instructions before beginning.
-Double click the webosdoctor.jar file to launch the app
-Select your language then click next
-Accept the licence agreement, read the warning message then select next to begin the install.
-Be patient the process can take anywhere from 15min to 1hour to complete.
Is this a one time thing? Or do we have to reflash the firmware whenever we notice battery issues?
Every month or so depending on usage

The discussion over at Rootzwiki seems to indicate that it should be done every month or so depending on your usage. I turn my tablet off when I'm not using it actively so I can do it every couple months or so.
Use the battery monitor widget to check the sleep history. After you've run this procedure once it becomes very easy to repeat.

Hopefully someone figures a way to do this in Android, I don't even know my WebOS account and I've not bothered to even set it up, so webos boots to the setup wizard and I don't want to make another account. I only lose about 1% every 8 hours though anyway.
FYI, after doing the above I had to reinstall the hd fix patch. I'm on SGA's 4.2.2 rom. After reinstalling, all is good again.

Hopefully someone figures a way to do this in Android, I don't even know my WebOS account and I've not bothered to even set it up, so webos boots to the setup wizard and I don't want to make another account. I only lose about 1% every 8 hours though anyway.

Thank you for the heads up, I will have to make a note about it in my CM10.1 thread.:good:
Would give a thanks right now, but apparently I've hit my limit. Thanks.
BTW, What would be the difference of just doing "PmA6Updater –a" instead of the other full command?

I should add a little note about that. The shorter command flashes two firmwares (as seen in the video) and therefore takes a little longer but less time to type in. Once you've typed it once in the terminal you can just hit page up to bring up again for future flashing.
Just wanna say thanks again, my battery life has increased by tenfold.

Got "Unable to connect to service" when I tried to connect to the touchpad on a Win7 x64. Can't resolve the problem by re-install Novacom, re-connecting touchpad, or replace the data cables.
Finally get it to work on another Win7 x64 laptop with 32-bit Java installed. Wondering whether 32-bit vs 64-bit Java would make a difference.

I assume you were using method 1. Did you try copying the Java file, like in this note? Copy it with administrator permissions.
-Note* if you are using a 64 bit OS and get the Error "Windows cannot find Javaw..." you will need to copy the Javaw.eve from C:\Windows\SysWOW64 and paste it into C:\Windows\System32.

Yes, I was using method 1 and copied javaw.exe on both PC. I remember doing WebOSQuickInstall stuff when I first got the touchpad and try not to install WebOS stuff if I can avoid it.
Finally, I am seeing lots of -3 and some -4 from BMW when I was content with -19. From the early A6 thread, I though that I would have to re-setup everything for the touchpad.
Thank you very very much.
Would this wipe my sd ?
having issue.while input PmA6 updater -a, it said can't open A6 device??
Does this affect everyone? I haven't had a problem with battery life since JC fixed the deep sleep in cm10

I am running CM9 and have noticed this. If you shut down the device from within android, the battery will drain... even with it shut off (not talking about sleep, but rather having the device off).
My solution. When your in CM9 or whatever android version your running, reboot the device. When it reaches the Moboot screen, toggle down and select power off. Your battery will not drain. I can leave it unplugged for weeks and it holds its charge.
More info needed

Lets see your battery monitor widget history. There should be gapps from where you have the tablet turned off and on. This could also be a symptom of your battery health deteriorating. We were just talking about these sorts of problems today.
Nevertells has another battery health thread here:
unable to find wterm in Preware, used Method 1
Just to mention this, I used to have all kinds of stuff installed in WebOS when I first got my TouchPad and then it died on my and had to use the TPDebrick process in RootzWiki to bring it back to life... anyway, I know I used to have terminal installed but I also remember having to add feeds so that I could find the terminal package.
This time around, I had only gone through the WebOS wizard because I needed to connect via USB so I could add the cminstall folder to the SD so I could reinstall Android...
Long story short, when I went into the Preware app to search for "wterm" it was nowhere to be found in available or installed packages... so I used the Method 1 and it worked just as well, the whole process took no more than 5 minutes
So, if anyone knows what feed url has to be added to Preware to find wterm it may be helpful...
Thanks for all your work guys on keeping the TP alive
PS: the only reason I flashed the A6 firmware is because yesterday I finally made the leap from CM10 to 10.1... I even dirty flashed on top of the 0418 CM10 build and have had absolutely zero issues (I just hate the dang navigation bars in the center but I like the status bar on top because I can now use CoolTool again :good:
PPS: Just want to mention also, I have read in a couple of threads that Windows 7 x64 users haven't been able to get UMS drivers to use the TP in mass storage mode in case anyone has any suggestions for that as well...

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). In the window that appears, go to the Details (Details) and there in the drop-down menu choose the Hardware ID (Hardware IDs). Our interest rates VID and PID, as shown in the picture Figure_2.
Transfer the VID and PID values in the respective fields of Manufacturing Tool, section SoC Devices.
- Disables the tablet holding the POWER button for 10 seconds and disconnect the USB.
- We keep the tablet down the VOL- and POWER to enter the mode droidboot. Once this happens, connect the USB cable again, go to the Device Manager Windows (Device Manager) and - as before - we find the values of the PID & VID Android ADB Interface (values are different from the previous Figure_3
Transfer prices PID & VID Manufacturing Tool in their respective fields of unity "Android devices", so o Dialogue Manufacturing Tool will be something like shown in the picture. Press "Apply" and "OK" to save the parameters. Close the application.
- Disconnect the USB cable from the tablet and disable.
- Xanatrechoume the Intel Manufacturing Tool as managers and go to the menu File -> Open. There, choose the folder of ROM (X98_Air_3G_ (C6J6)), find the file "flash.xml" and open it.
- We keep the tablet down the VOL +, VOL- and POWER in order to display the logo of running Teclast DnX, 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 disable the X98 Air 3G.
The conversion process in Android tablet has been completed.
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.
For more detailed tutorial look here : jcespi2005's tutorial
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!
Remember: You can disable xposed at boot by repeatedly pushing a hardware button as the tablet begins to boot. For example you can use Vol + button.

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".

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

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.
11) Q: I have installed dualboot bios with a success. 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:
blackman818's tutorial
12) Q: Why Microsoft Store doesnt work?
A: (Thanks to @Hendrickson ):
Run the troubleshooter (Search and type trouble shooter) And run it for the Store, this should re-install the drivers
13) Q: Why camera doesnt shows anything (the screen turns black and i have to exit to desktop)?
A: (Thanks to @Hendrickson ):
Reinstall the camera.inf and OV and GS camera drivers from the Air 3G drivers
14) Q: I can't use touchsceen and also screen rotation is not working. During installation , Windows stopped at language selection ,i had to connect usb moude and keyboard to make selection, is this normal?
A: (Thanks to @25gee ):
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 ):
Find an USB keyboard first and plug OTG cable to the tablet and turn it off. Turn the tablet on and immediately press ESC button. And follow the images (bios_1 and bios_2) i attached and do the settings carefuly. f4 save & exit
17) Q: I have problem with the dual boot bios, now I don't arrive any more to the page where there are the icons of the Android and Window (that I never saw it). Please could anybody known what happens, I am stacked on the installation of windows?
A: (Thanks to @grigoris_a ):
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. Everything perfect but... right now I cant install android because my tablet is not recognize by the PC I power off by pressing 10 seconds the power button. 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.
Sometimes there pops up chinese messages in the infobar (lower right corner in windows - left to the clock).How can i remove this?
A: (Thanks to @smartchip):
On Control panel : Clock, Language and Region : Language : Change date, time or number formats. On Formats tab - Match Windows display language (should be default). On Location tab - change "Home location" to get your Start Menu tiles to load news, recipes, etc from your country (open the apps when you're done and refresh). On Administrative tab - "Welcome screen and new user accounts" click "Copy settings", apply to all.
21) Q: I have teclast x98 air 3g dualboot version but accidentaly i touch in corner to swich off choosing the system, now i have only android.How ca I return to dual boot menu?
A: (Thanks to @smartchip):
Hold power + volume up to power on. You'll get the menu back
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!
HARDWARE AND LOW LEVEL FIXING
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.

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:
Click image for larger version
View attachment 3050134
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

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.

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".

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.

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..."

- 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.

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.

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.

SLEEP PROBLEM IN WINDOWS 8.1 (thanks to sasort)
Follow these istructions:
First open cmd as admin and check status with this command:
powercfg /sleepstudy
It should give you this reply:
No connected standby traces available. Report not generated.
Now start regedit an go here:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Power
Change the value of the key CsEnabled from 1 to 0 and reboot.
(1 means connected standby enabled and 0 disabled.)
After reboot.
Now go to the control panel and select Energy, under Advanced there will be many new settings.
Don´t change anything, just select save settings.
Then with regedit change the CsEnabled key back to 1 and reboot again.
Open cmd as admin and again check status with the command:
powercfg /sleepstudy
It should now work and create a sleepstudy-report.html and the sleep function now works as expected.
MANAGE APP UNDER ANDROID (thanks to jcespi2005)
You can use link2sd to move app, libs and data, and FolderMount to link and move OBB and SD data to microSD
BATTERY DRAIN FIX UNDER WINDOWS (thanks to vpx)
The main problem is very old (year 2006) driver of "Intel SD Host Controller", they are 3 in Device manager. Only thing what you need is update driver.
start Computer Management (hold My Computer and select Manage)
select Device management
find SD Controllers, if you click on it, there are 3 "Intel SD Host Controller"s
hold on every one controller, select "Update Driver", select driver from computer, and there is another option "SDA Standard Compliant SD Host Controller", install driver, confirm restart of computer after last update install
reboot

If you see that ping on windows is very strange,sometimes i have lost packets and ping time is not stable try this fix: techtablets repository
BATTERY CALIBRATION FIX UNDER ANDROID (thanks to Hendrickson)
Try this, download and run advanced battery calibrator from Play and Battery Life repair:
Blackmart Studios - Battery riparator
Blackmart Studios - Advanced Battery Calibrator
This seems to have fixed the issue.
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):
http://www.arctablet.com/blog/wp-content/uploads/2014/02/RK3288-2-nowrmk.jpg
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?
