[Teclast X98 Air 3G] GermainZ:
As some of you have noticed, a new forum has been created for the Telcast X98 Air 3G. Some threads have already been moved there -- please report any that haven't been and we'll get to them. Some tips to get started:

X98 Air 3G General: this is where guides, ROM shares and general discussions should go.

X98 Air 3G Q&A, Help & Troubleshooting: should be pretty clear. For general questions, this is where you need to go.

X98 Air 3G Accessories: this is a more specialized "General" forum about accessories, such as cases or screen protectors.

X98 Air 3G Android Development: Android related development: ROMs, kernels, recoveries.

X98 Air 3G Original Android Development: same as above, but for what's considered original to the device (e.g. first 5.x ROM ever, or a ROM that has useful features not available in any other ROM for the device).

X98 Air 3G Themes and Apps: this is also a specialized "General" section for themes and apps, but should mostly be used for apps and themes specifically developed for this device.

Developers are highly encouraged to start threads (or DevDB projects) for their ROMs in the Development forums. That'll allow them to have organized discussions about their ROMs, update their users via DevDB and more.

Cheers :)

I jumped before the dual boot was announced. I got Windows 10 Home US English, so it's the so-called International version. For some reason the speakers in mine are awful - much quieter and tinny than my Air II and I've found no fix for that. Hmm...I'm wondering...maybe only one is working. Under Windows, at least, the Air II speakers are quite loud. The real issue, as you probably read from Techtablets, is overheating and throttling. The Cherry Trail in this thing runs crazy hot, hitting 85+C in demanding games and instantly while playing 4K videos. Thermal limit is 90C. The Bay Tail in our 3G and Air II hums along in the 50s. A copper plate heatsink over the CPU drops the X98 Pro temps to about 80C, stopping throttling, BUT that is still crazy hot and will cause instability and other issues. I'm thinking of trying to return this, although I wonder how well that will go over with my Aliexpress vendor....as well as shipping it back to China.
[Teclast X98 Air 3G] tecknight:
I am amazed that Teclast didn't add any heat sinking to the Pro. The 3G even had overheating issues.

What could they possibly have been thinking ?

They are essentially using the same motherboard and case as the Air II/3G

Here is what you will need to do:

1. Select and download your ROM here:

2. Install the Intel MFT on a Windows Host PC. Instructions are here:

Allview Viva i10G

Hi, I also have a Allview Viva i10G (rebranded Teclast x98 Air 3G), I flashed the stock Android rom again with resized partitions and flashed DUALBOOT 2.02 bios from Teclast with ANDROID ADB method, but the tablet didn't restarted after successful bios flash. I think I have a brick.

As I understand some of you also bricked your tablets once, I just want to make sure it's bricked and not stuck in a bootloop that I could fix somehow.

So here it is: If I press POWER, the tablet starts up and shows a fully loaded battery graphic with 9C small text besides it. It shuts down after 2 seconds. USB stick doesn't flash if inserted in OTG cable, I also tried all key combinations to enter bios but nothing works?

IS IT BRICKED??

P.S.: I also tried to flash the chip using a programmer with the same 2.02 version but the tablet reacts just the same! I know that people already installed a windows bios to this exact tablet and managed to run windows just fine, so really I'm lost... What should I do? Maybe It's compatible with a specific version of windows bios, maybe 2.02 doesn't work properly with it, maybe I should try a different keyboard (I cannot access bios at all but flash is successful with programmer)... please help!

P.S.2.: Maybe flasher is not working properly because the chip is 1.8V?

[Teclast X98 Air 3G] tecknight:
If it is displaying ANYTHING on the display, it is not "bricked". However, that doesn't necessarily mean there is a way to fix it.

I have never heard of an Allview Viva i10G and I am not sure that it is compatible with X98 BIOS images.

Try powering up holding VOL-- and VOL+ and POWER until you (hopefully) see Entering DnX mode in small letters.

If that works, you may be able to flash an image to emmc using MFT

[Teclast X98 Air 3G] supercowz:
From PM :)

even buggy do you have/boot win8.1 ?

1)re-install or launch win8.1 on your tablet with help of usb keyboard and mouse

2) dl on your tablet

https://www.dropbox.com/s/8tk5nyumvhikvhr/BIOS_X98_Air_3G_win_to_android by supercowz.rar?dl=0

3) you need to know your VID and PID values for ​​Manufacturing Tool, section SoC Devices for flashing android image after you flash the android bios... get them before you cant boot windows (please check with first post TuTo)

4) if you have C8J7 Run with administrative rights (from command line) flashC8J7.bat file inside the folder

if you have C6J6 Run with administrative rights (from command line) flashC6J6.bat file inside the folder

then flash android image for your model ID with Manufacturing Tool

[Teclast X98 Air 3G] G3n3R4L:
once you will receive the windows tablet, you must take a copy of all the drivers for yourself first just in case because teclast till now didnt announce any support on windows at all so you will be having the recovery partition but still ..... you will need to take the drivers backup "search on google for any app that take a backup from installed drivers" and still if you will upload the bios you must upload the drivers backup also because without the drivers backup no will can install a stable windows on the c6j7 bios ........

hope you could mention in the first post that this method works fo "c6j6" because someone just flashed the bios of c6j6 version on c6j7 device .... so people could be careful insread of having unstable windows

OK, the log that you posted is an MFT log. Are you trying to flash it using MFT ?

If so, are you booting your X98 into DnX mode by holding POW and VOL-- and VOL+ until it displays entering DnX mode. ?

The MFT errors you are getting indicate either a driver problem or an MFT configuration problem.

First try downloading and running this on your PC with MFT installed.

Download MFT timeout Fix

1. Extract archive to a folder on affected PC

2. Right click on 3-RunAsAdmin-ApplyCustomConfig.bat, select Run as Administrator

Batch file will apply MFT custom configuration in 2 INI files.

3. Try MFT again and see if it works.

If it still gets the same error, then go to Control Panel->Programs and Features and uninstall the Intel iSoC drivers

Then do this:

Install adb drivers for your X98

Once you are done, reboot your Windows PC and try flashing your X98 again.

You don't use the "move to SD Card", you create links. That will move the stuff to the SD card and create virtual links; using your 2nd Partition. It's really very similar and does the same thing ultimately.

You could try using parted under android.

Download it here:

Extract the binary from the zip.

Then copy it to /system/xbin/ in android

and run this command from a root shell:

chmod 755 /system/xbin/parted

Then type this from a root shell:

parted /dev/block/mmcblk0

then type p + Enter to list all the partitions

type h + Enter to list the commands available.

The resize command is probably what you are looking for

Can't load Manufacturing Flash Tool - WDAPI1140.dll error

Is anyone else having a problem following tecknight's instructions [here and here] (to the letter) when they try to load MFT?

MFT does't load for me. Only displays the error message:

ManufacturingFlashTool.exe - System Error

The program can't start because WDAPI1140.dll is missing from your computer. Try reinstalling the program to fix this problem."

I've tried on Windows 8.1 and Windows 7, still the same problem. And yes I've installed the Intel Adb drivers 1.10.0.

I can't find this WDAPI1140.dll anywhere. I've seen a few people mentioning that they have a similar issue, but they don't say how they resolved it. (If they actually did)

[Teclast X98 Air 3G] tecknight:
That specific error means that you didn't install the iSoC USB drivers

The interesting thing is, you don't actually need the drivers on Baytrail devices (they actually do more harm than help), but MFT checks for the presence of that DLL. at load time.

The iSoC driver install is included in the tutorial and install archive, so if you followed it, you shouldn't be getting this error.

http://xdaforums.com/showpost.php?p=62823535&postcount=5

You can download just the iSoC driver installer here if you like:

Download Intel iSoC USB driver installer

You can also uninstall the driver once MFT has launched successfully and MFT will continue to run thereafter.

This is actually what I recommend, as the iSoC drivers have a nasty tendency to block MFT's ability to detect an X98 in DnX mode.

Cheers tecknight. Not sure why but the version of your post I was reading didn't have the latest update I see now unless you've made it in the last 24-48hours hours. Don't currently have internet access at home/been sporatically working on it. Had the issue for a few days, but hadn't had the chance to post anything.

Luckily I had already figured out the problem was the iSOC install though, but I did run into another problem. (you may have already fixed this too)

The "3-RunAsAdmin-ApplyCustomConfig.bat" file used to install the MFT tools has an error in it.

The 3rd line:

"copy "ini\Manufacturing Flash Tool.INI" "C:\ProgramData\Intel"

Should be:

copy "ini\Manufacturing Flash Tool.INI" "C:\ProgramData\Intel\"

(Missing the trailing slash)

May seem like a small thing, but I've just spent hours scratching my head as to why MFT wasn't detecting when I plugged in the tablet in DnX mode. Lightbulb moment was after I tried updating the INI files to have debugging enable when loading and found I couldn't find the "C:\ProgramData\Intel\Manufacturing Flash Tool.ini" file, but I did find a "C:\ProgramData\Intel" file (no extension) that was the INI file. Figured it created that extensionless file during the batch copy and wasn't actually being used when MFT was loaded. I added an extra line to the batch to check for the Intel folder and then copy the INI file:

if not exist "C:\ProgramData\Intel\" MD C:\ProgramData\Intel\
copy "ini\Manufacturing Flash Tool.INI" "C:\ProgramData\Intel\"

Worked like a treat after that!

Thanks for your work!

[Teclast X98 Air 3G] tecknight:
Yes, you were one of the lucky ones that downloaded it during the less than 24 hour period where I had the iSoC driver installer removed.

I figured, incorrectly, that if MFT worked after I uninstalled the iSoC drivers, that it should also work if I never install the iSoC drivers at all.

Now this other item you are pointing out seemed like a big deal when I first looked at it. Then I thought, why is MFT ever working if it's never getting the .INI copied over. Then I realized, the .BAT file works fine as long as there is a C:\PROGRAMDATA\Intel folder.. Since that .BAT file runs after the MFT install, the folder should exist, as it should have been created by the MFT install.

Thanks for catching it, I think the additional logic you added makes more sense anyway, as you never want to assume the install created the folder

Edit:

Now I remember this script. The first two lines:

set scriptpath=%~dp0
cd %scriptpath%

are to unhijack the working directory. For some reason, when you tell Windows to run a .BAT file as admin, it changes the working dir to \Windows\System

Also, in checkout, they offer a shipping option called Priority Direct Mail (3-7 business days) for free. I resolved the low speaker volume issue with my Windows only X98 Pro via a software booster (DFX Audio Enhancer Plus - $29; maybe there are free ones out there, but I couldn't find one for Win 10). The speaker itself is fine (after boost); it's just driven at low max volume in Windows for some reason; maybe BIOS/driver fixable. Not everyone has that problem.
