If you've got MIREK rom,just apply what stated on post 2 as MIREK has added init support and root to the distribution.

Have a look to second post section "3D GAMES FREEZES FIX"

---------- Post added at 16:32 ---------- Previous post was at 16:10 ----------

I've found these two directves in the AIR 2 variant that differ from 3G one:

ro.wisky.gpssupport=false

persist.nomodem_ui=true
[Teclast X98 Air 3G] royeiror:
Could you post what these modules are? I have mirek's V3 on an Air II and would love to disable phone and GPS

---------- Post added at 09:44 AM ---------- Previous post was at 09:37 AM ----------

You can flash mirek's rom, he included 3 xml files so you could wipe everything, wipe Android or wipe nothing. ?He recommends wiping Android but it's up to you.

The ROM can be found in his Google Drive Repo (in his signature, he has a post almost every page) and the instructions can be found in the first page of this thread.
[Teclast X98 Air 3G] BoORDeL:
these are not modules but BUILD.PROP configuration.

Download from playstore a program to edit build.prop and add those directives.

Anyway, before doing this operation wait for MIREK cause you may get an unusable system (and reflash android again).

If you are not afraid to flash system again you can try.
[Teclast X98 Air 3G] royeiror:
Isn't Build.prop just a text file that's easy to edit with any file manager?
[Teclast X98 Air 3G] BoORDeL:
Yes sir, but rember to maintain file properties.

The simplest way is to use a free program to edit it.

it's ur choice ;)

EDIT: just to follow the correct way to edit it http://xdaforums.com/lg-g3/general/guide-build-prop-tweaks-free-ram-t2825693
[Teclast X98 Air 3G] royeiror:
So what lines do I need to edit inside build.prop?
[Teclast X98 Air 3G] BoORDeL:
you have to add these 2 lines:

ro.wisky.gpssupport=false

persist.nomodem_ui=true

beware preserve file attributes if you edit it with a generic file editor.

Which mirek rom versions is better? version2 or 3
[Teclast X98 Air 3G] Superjets:
Hi, it was not correctly put in my original message. Your current windows setup will remain as it is, as long as you don't make any changes to it. Bios update will not affect your operating systems that way. But in the future the key will not be in bios for handy installation anymore, but if you need to re-install and activate your windows again you need to do it manually with the key. So everything went fine and you probably have a new bios now.

You can check it by plugging an usb keyboard to tablet with otg cable. When booting tablet, tap delete repeatedly and the tablet boots directly to bios. On the front page it should say the bios version. Or you can just charge it to 100% and leave it on overnight with windows on. In the morning if you have like 95% left (instead of 30-40%..) your bios was successfully updated and you just say thanks to Mirek190 :)

Thanks for that,

Can you just confirm this is correct before i brick my tablet,

Android upgrade only! Leaving windows untouched!

1. Root Tablet

2.Download Mireks Rom (Ive downloaded his 3.0 beta version)

3.Download Manufacturing Flash Tool, install the drivers and flash tool.

4. Put tablet into DNX mode?????????????????????????????

5. Run flash tool and select .xml file. I would select the "flash-system_only_and_format_data" (is this the right one)??????????

6.WAIT!

7.Restart tablet, Then im hoping its done???

Is this correct or am i missing anything?????

Thanks.

I have successfully fixed my previously bricked C8J6 Teclast X98 tablet using the CH341A flasher I got from eBay.

What didn't work:

- Connecting the chip to the flasher.

- Flashing the BIOS backup I made.

What did work:

- Connecting the chip to the flasher.

- Erasing the chip.

- Flashing the BIOS backup I had made.

What also worked:

- Connecting the chip to the flasher.

- Erasing the chip.

- Flashing the 2.02 BIOS that had originally bricked my device.

So the important thing here is, to erase the chip before flashing. Also, somebody on YouTube said that flashing will only work at 1.8V, but I flashed using the CH341A which uses 3.3V and it worked fine.

So now I can confirm that the BIOS 2.02 version does work on the C8J6 model as long as the chip is erased first, and then the BIOS is flashed.

Edit: Some photos imgur.com/a/WgyX4

[MENTION=3184697]MaK11-12[/MENTION]

That's some good news, with a programmer at hand could you test if this is working as well for you?

FPTW package

fptw -erase
fptw -f X98_Air_3G_Dual.bin

This should be comparable to the CH341A flashing process.

fptw -erase
fptw -f backup.bin
fptw -f X98_Air_3G_Dual.bin

If this results in a bricked device, than it is indeed caused by the (incompatible) previous bios version.

Hi [MENTION=228925]Mirek[/MENTION]90

Unfortunately on C6J6 after flashing 2.02 Dual BIOS front camera no longer works. It's reported as OV2680 from the 2.02 bios and even if I load the appropriate driver (from windows) it fails to initiate camera. At least the battery drain is solved! I don't know if you have any idea to get front camera working since you have an old c6j6...

thanks
[Teclast X98 Air 3G] jsager33:
I too had success flashing my bios with the CH341A flasher. I have an X98 Air II HG9M tablet. My steps were:

- Connect chip to flasher

- Erase

- Blank (confirms erased)

- Program (X98_Air_II_Dual.bin)

- Verify (confirms chip data = file data)

I flashed from Windows 7 which didn't allow the driver to install since it wasn't appropriately signed. Had to reboot Windows, hit F8 to get to Windows boot options and select option at bottom of list to boot without signing verification. I could then use the CH341A and program the bios chip.

Also, after I programmed the chip my tablet still wouldn't start up. I programmed the chip a couple of more times before the thought occurred to me that my battery might be dead. I charged it for about 15 minutes or so and the tablet started up with the new bios dated 4/21/2015.

Nice to have the X98 working again. [emoji4]
[Teclast X98 Air 3G] nafrench:
HG9M bios question

I just recieved Air II 64 GB HG9M. I have read in the thread that some people have success with 2.02 BIOS to solve standby battery drain. I have updated WIFI, BT and changed the SD driver per the thread to all latest versions but I still got over 5000mW drain last night whilst in connected standby. My question is will my new tablet already have latest BIOS? Any way to find the bios version without connecting keyboard? Lastly are any BIOS available confirmed working for HG9M? Most resources are for Cxxx series AIR 3G devices but I think the BIOS may be compatible with Hxxx series?
[Teclast X98 Air 3G] MaK11-12:
Graphic rendering is quite slow after I flashed BIOS 2.02 on my C8J6 Teclast tablet. The graphics driver is now detected as Microsoft Basic Display Driver which I presume is software rendering. The Intel HD Graphics drivers were already installed previously but are not being used for some reason. Trying the update the Microsoft Basic Display Driver in Device Manager doesn't work either.

What can I do to get Hardware Rendering to work again? Do I need to reinstall windows after the flash? Drivers?

To confirm, Linux detects the Intel VGA Graphics controller.

Edit: Restoring driver backup worked! ^_^

[Teclast X98 Air 3G] royeiror:
There is a step you're missing, you need to find some values to enter in the configuration of the Intel flashing tool. You can find the walkthrough in the first page of this thread. Also you don't need root, you require ADN debugging.

Also you run the tool, select the XML and then plug the tablet. The instructions are very detailed and will work if you follow them.

See post #9214 in this thread from mcjamez re: flashing from Windows on this tablet. I bricked mine trying to do the Android flash using my PC and I had to get the CH314A programmer to bring it back from its bricked state.

[Teclast X98 Air 3G] oam_xda:
Thanks for the success report :) Some questions....

I also now have the C341A flasher and trying to get it to recognize my chip before I flash.

The software says Device state: Connected in the bottom right corner but it doesn't detect the chip.

- When your BIOS was bricked, did the flasher program DETECT the chip correctly immediately as in your picture? For me it just says Other/Unknown etc... It is actually a W25Q64FW chip.

- Could you post a clear photo of the connections both on tablet's end and in the flasher end? I could verify my connections are setup the right way. I have setup the clip+cable red lead to chip pin 1 and on flasher "adapter piece" I have put the red lead to the pin where it says 1. Then in the actual flasher device the adapter is placed same way as yours - I think, but not sure.

thanks!

OaM
[Teclast X98 Air 3G] SkOrPn:
you do realize that the small picture on the 341A is incorrect right? According to several videos, you have to have the chip turned around in opposite from what the picture says. I do not know if this oversight has been corrected or not.

Here is a video explaining the correct orientation https://youtu.be/L0ChYNwunUE (go to 6:23 and he will explain the orientation to you)
[Teclast X98 Air 3G] jsager33:
I attached an image of how I had mine oriented. I also added an image of the clip adapter board I used. Pin 1 was plugged into the Pin 1 hole on the CH341A socket as pointed out in the picture. This worked for me.
[Teclast X98 Air 3G] oam_xda:
Thanks for replies, guys!

Yes, I have seen this video too, and I have the same pic in my prommer. I knew that is wrong :)

My prommer and adapter are not exactly the same but I also have connected pin 1 to pin 1 on both ends. I.e. I connect the red wire in the cable to pin 1 on both ends. Still no luck, I have tried all combinations just for the fun of it by now but it doesn't detect the chip.

This is my prommer.

And this is my clip cable.

So..i made the big mistake in installing win 10 tech build. I cant get back to android so i can get back to win 8.1. No matter what i press it ignores and go straight to windows log in, power on, volume up and down, power on volume down or up seperate tried with no luck.

So im basically stuck. I am considering getting a new china tablet as i am giving up on my Teclast x98 3G. I am fully aware that this is my mistake, just bloody annoying. I can get inside win 10 on it, but no touch and screen reverts opposite so its not really usable to browse around at all.

Last hope is some one can give me a solution to either revert it, or fix the screen and touch. I tried the 8.1 fix but that actually made my screen go opposite before i didnt have the problem.

Hope you undestand what i am trying to explain.

When I connected my flasher to the laptop Windows 7 64bit detected it and installed whql drivers right away?! When I looked at the driver data it was the same as in the zip file that is flying around the net, except signed. Same version and date.

The flasher shows in device manager under interfaces.

Did you guys install any other drivers? Somewhere there was a USB -COM driver too, do we need that also?

Another question. Does the tablet have to be charged before it can be flashed? Mine is certainly dried out after 2 weeks of waiting and I don't think it even charges while being bricked, or does it?

But really, You had 98% chance to ruin your tablet:

2. CH341A doesn't work natively with 1.8V flash chip as "FW SIG"

i dont know 100% but i think the issue is more the adroid os or display driver, as i can run hearthstone in windows on medium locked at 30 fps but on android the same game is very choppy and laggy, except sometimes if i reboot, run battery doctor and kill all processes then open the game with cm's game booster, i can get smooth gameplay. i think a better fix would be finding out why its choppy in the first place because lowering the resolution in windows has little effect so i think its something else botlenecking the gpu or something, maybe even heat throttling.
[Teclast X98 Air 3G] jsager33:
Windows wasn't able to find the driver on its own. I had to install the driver manually. It looks like your all set in that department.

Instructions I have seen elsewhere indicate that you should unsolder the red wire before programming the chip. There is another post just after yours warning that you could damage the chip if the tablet is powered on when programming it. My battery dried out by the time I had what I needed to reprogram the chip which may be why it was successful for me since I did not unsolder the red battery wire. Without enough battery power the tablet eventually shut itself off, even though there was no way for me to know since the screen was off in the bricked state. I did notice that my tablet would not boot after I programmed the chip. I had to charge the battery after I programmed the chip to get the tablet started. Don't charge the battery until after the chip is programmed.
