flash

Yes, flash is not supported for Android anymore. Somehow we tried to use it applying archived versions_ for Mediatec platform for example.

However can you see those inserted "films : at Polish tvn24 site? How?

I cannot confirm that flash is needed there. But some tablets can do it, some - not.

[Teclast X98 Air 3G] mirek190:
Mediatec is still arm cpu - Intel is x86 cpu.

On website you not need Flash for it . ( and as far as I know works only in Poland tvn streams ) - apart from that you have app from tvn that stream tvn24 .

not working for Tablets with special BOOT.IMG

ATTENTION ... Tablets needs the special Boot.img does not install it, because the touch screen stops working ...
[Teclast X98 Air 3G] tecknight:
My french is rusty, but I believe it says adb is not a recognised program or internal command..

Are you sure you are running the script in the folder you extracted all the files to ?

since the folder contains adb.exe the error you are getting should not be possible unless you are not running the FLASH.BAT from the folder you extracted the files to.

---------- Post added at 07:39 AM ---------- Previous post was at 07:31 AM ----------

If you have a tablet whose touchscreen is not recognised by the normal boot images then of course this won't work as this fix flashes a custom boot.img based on the V4 C8Jx kernel

However, give me a couple of hours and I will make you one that will work for your tablet.

Ensure USB debugging is enabled.
Browse to the Folder on Host PC and launch B2WinFix.bat
Once it detects your device it will let you continue by pressing a key
Your X98 Air device may display an SU dialog. If it does, you must GRANT SU privs.

Hi Tecknight's,

I dont undertand why Boot1 or Boot 2 not working for me. I have a X98 air 3g 32 c9j8 - Mirek190 KK v4 - bios 2.02.

When i press Boot to Windows, my tablet shut down, bios start '"TPad" picture, and after i have the green icon of battery but dont start windows.

Soory for my English ;)

Maxedout,

Do you have any pictures by any chance ?

I am getting ready to open mine up.

---------- Post added at 08:42 AM ---------- Previous post was at 08:40 AM ----------

Try it without cable connected to the tablet.

That is normal behavior of the tablet when a charger is connected. It's stupid I know, but that's what it does
[Teclast X98 Air 3G] Franckydiam:
I try it, but the tablet boot to ... android :)

Perhaps GravityBox prob ?

I try desactived GravityBox, same prob so... ?? :(
[Teclast X98 Air 3G] tecknight:
Your tablet is a C9J8 so unless you have a tablet where the touchscreen is not detected by normal images, I haven't released a fix for your tablet yet.

The first image is for C8Jx and the second is for SPECIAL touchscreen units.

That being said, I would still expect that first image (for C8Jx) would probably work ok on your variant.

You are absolutely certain your BIOS is 2.02 ? Have you brought up the BIOS screen and checked ?

I have exposed framework and gravitybox enabled on mine and it still boots to Windows perfectly.

Tell you what, I will make the installer for your model next.

Yes you can. Do this:

Boot tablet to android

Connect your tablet to PC with cable.

On PC go to CMD prompt in the same folder where the .BAT file is and type:

adb devices + Enter

If it works and shows your tablet, then try

adb shell + Enter

Are you using a data cable and not just a charge only? The factory cable is data. I used the adb drivers that are on techtablets specifically for the Intel, could try Intel adb drivers.
[Teclast X98 Air 3G] tecknight:
Here is what you need to do.

Connect tablet running Android with USB debugging enabled to windows PC

Go to device Manager.

You will see an undefined device

Right click on it and select Update driver software

Then Browse my computer for driver software

then let me pick from a list of device drivers on my computer

Then Select Android device and Android composite adb interface

then next.

It will warn you, but install anyway

after that adb will work
[Teclast X98 Air 3G] siezed:
I'm trying to figure out what causes this as mine does it too, in the meantime a temporary fix is to do a battery calibration by running your device all the way down and let it sit for 5 hours, or keep trying to turn it on till you don't get the battery message, then fully charge while off. You can check the battery charge by holding the power button for 2-3 secs, any longer and you'll power on though. Then just use one os per charge if you need an accurate reading, for some reason it seems switching os's mid charge causes this battery calibration issue.

[Teclast X98 Air 3G] djmvt:
Same issue with mine :(

it also reports too high calculated power usage in settings/battery, seems to me this is related to the problem.
[Teclast X98 Air 3G] LVL91:
Then I can't think of anything else then a hardware issue. Mostly the problem is related to entire batches or versions of the product.

I just hope my new tablet coming from the same supplier doesn't have the same issues, would be quite frustrating then....
[Teclast X98 Air 3G] Davercade:
I'd be inclined to agree, let us know what the result is and also if the touchscreen is better. There is movement between the screen and the case when I press on it and I wonder is that my problem (poorly fitted digitizer)

It's a shame because the tablet is brilliant otherwise, if the screen was better I'd get rid of the iPad an use this all the time...
[Teclast X98 Air 3G] LVL91:
I couldn't agree more. It's a brilliant tablet, but make it $20 more expensive with better quality checking and some little updates and you've got yourself a killer tablet.

Sadly it's a chinese tablet, and chinese don't have the same perspective on products as western people do. (quality matters!)
[Teclast X98 Air 3G] malojk:
What exactly you have provided reason for the complaint, and if you have any problems with this? They turned you money?
[Teclast X98 Air 3G] LVL91:
They asked for proof, so I made a video to show the problem. They asked me to return it, but I'm going to wait till I get my new tablet.

Then I'll make another video of (hopefully) showing that my new tablet doesn't have these problems. I want to capture that video because I bet the people from TinyDeal won't see the problem and will ask me again about the problem. I'd much rather be prepared for the worse than to go through the whole process of explaining stuff again...
[Teclast X98 Air 3G] malojk:
But it will send a new waiting for your broken tablet or already sent a new one. Do you understand what I mean?
[Teclast X98 Air 3G] LVL91:
No that is not what I mean. But I do understand what you are saying. Let me explain. This is my plan:

1. I ordered and got my 1st X98 Air 3G

2. Saw GPU issues (I wanted to compare it to another X98 Air 3G)

3. I ordered and got my 2nd X98 Air 3G

4. Verify that my 1st tablet indeed has gpu issues

5. Return the 1st X98 Air 3g and get a refund for 1st or 2nd X98 Air 3G.

They didn't already send me another one, I ordered it myself.

This is what normally happens:

1. I ordered and got my 1st X98 Air 3G

2. Saw GPU issues (I wanted to compare it to another X98 Air 3G)

3. Returned my first X98 Air 3G

4. I have to wait for a VERY long time (shipment, TinyDeal checking, maybe some repair, sending a new one)

5. Get a new or repaired tablet which hopefully works.

I did the first things because I want to verify that it's not the tablet itself. (it probably isn't)

If TinyDeal got a wrong batch, I'll likely receive another faulty one. Then I can at least return both broken tablets and save some money. :)

Hopefully you get it now :)

[Teclast X98 Air 3G] WSOFT2002:
Hi there,

I also get a X98 Air 3G at mid of Oct, I have no problem on playing movies and mini games likes Tsum Tsum, Candy Crush, but it hangs every time (Within a minute or tow) in heavy 3D game like GTA VC, Real Racing 3 . When on some not so heavy 3D game like Dungeon Keeper, it just hangs randomly (I can play up to a hour with no problem or hangs within a few minute with the same game). I am running 1.10 firmware which come with the machine

I flash it into "Windows 8.1 with bing" this Monday, so far the battery performance under windows 8 is better then Android, but still having issue on heavy 3D game hangs like Asphalt 8.

I have different steps for flashing the bios for windows , with below steps you don't need to root the machine first.

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

As you can see I add "adb root" and remove the "adb su" step, With "adb root" it will reboot the machine into root mode, so no need of "adb su" . You will see the prompt change to "#" after "adb shell" , the prompt is "$" when normal.
