Same here, wifi is always connected in Teclast Air X98 3G C6J6 with KitKat 4.2.

Using wakelock detector reports:

- wakelock CPU: 1013 (AudioMix) and Servicios Google Play

- wakelock of kernel: powermanagerService.wakelocks

- wakeup lanuchers: servicios de google play

Using Gsam Battery Monitor reports: wifi active the same time last charged and applications use (android system) draining more battery than screen...

Let's hope this can be helpfull

Hey Mikha,

If it works, try on 2.02 :D
[Teclast X98 Air 3G] k2thec:
Hello Mirek and thank you for your support,

I have a model c8j6 upgraded to bios 2.02

v5.0 has real promise, generally works well and has seemingly fixed an issue I was having with wifi turning off every time the screen sleeps on stock kk (may have spoken too soon on this one.) Also no more throttling screen brightness messages constantly and better volume!

I am having a few issues with v5.0 however

1. catlog seems to never show any information

2. when I try to use xprivacy for xposed it causes constant crashes and reboots

3. xfinity tv go app crashes when trying to watch anything

4. when trying to change the clock position within gravitybox android crashes

I have a crash log for xfinity tv go I found on the emulated internal sd luckily because catlog does nothing.

here it is

http://pastebin.com/s3j5KBck

I noticed the entry for xposed in the last line, but after disabling xposed it gives the same minus the last line.

I understand that you may not have access to use this specific app, but please let me know if I can provide any further pertinent information regarding any of the issues I am seeing.
[Teclast X98 Air 3G] mirek190:
Mostly if apos crashes then just not fully compatible with lilipop or with x86 architecture .

Even like you see gravity box is not 100 % stable on lilipop .

Audiomix - all apps when using audio ( youtube , music payer , mx pkayer etc )

Just bought a teclast x98 Air II with Windows 10 from Tinydeal, I think it's the same as the 3g but without the sim card option.

Has anyone had problems with this model? I saw a video on YT saying that the air 3g tablet crashes when trying to launch an steam game,and it freezes and stops working after some months,is this true?

Battery

Sorry but i haven't explained very well. In advanced settings i have only when connected, and the tablet is suspended all the time when i check reports of wakelock detector and gsam battery monitor.

If tablet is suspended why audiomix is draining battery?

Have you checked how long takes the tablet to discharge in suspension?

Thx again

Full disk clone backup

Greetings my friends! Any way to clone dump the eMMC to an external backup drive, USB Flash Drive (Pen drive) or microSD Card?

I need to backup everything including Windows and Android boot partitions, data partitions, recovery partitions before doing anything on the tablet.

Used to doing this on desktop and mobile HDD (EIDE/SATA) using DOS Norton Ghost 8.0 PE on Windows full disk clone (file structure and partitions and boot) but have no idea on how to do this on an embedded eMMC with dual boot Windows and Android.

Thanks!

Any fix for c6j6 camera with lollipop ?
[Teclast X98 Air 3G] jopebe:
Hallo all together,

I need help, because I found nothing about my problem.

I got my teclast x98 3g 32gb and did as follows:

1. Win 8 > set language to german

2. Win 8> several updates

3. Win 8> offer to upgrade to win 10

4. Win 8>upgrade to win 10

5. Android> flashed to Lollipop : great

Now: Win 10 gets no longer connection to Win AppStore. Have a microsoft account, can login there, can get, Skype; but no login in store possible! Everytime I choose Microsoft account, there came a black window for a moment, nothing else.

So I decided, to reset my win 1o without any personal settings.

That was a mistake: Now I have a boot loop: I always come back to the page, where I can choose the language. When I change it, after some rebootings comes very shortly a window, so short, that I can not recognize it. Than comes a window with defaultuser0, new reboot. Now I can choose the language again, an so on.

I tried to install Win 10 again with the original Iso and a Rufus-Stick. No installation method is possible, no repair mode goes.

Has anybody an idea?

Must/ can I format the C: - drive?

What can I do in the CMD?

Help!

No problem for me switching through different versions of mirek's navbar (I also have used solid explorer for this operation).

Sometimes you need to force restarting the system UI or trying to reboot the device in order to apply the changes.

I use Screen Shift in the place of Resolution Changer because it sets the resolution (and density) you want to be applied when the system start.

It also give you the possibility to create as many resolution's profiles you want, easily recalled.

Well I don't know whats got into my X98 3G/ Android 5 setup but my youtube wont work any more no matter how many reboots or what version of Chrome I use etc, it also seems to effect any kind of online web video (as well).

Will do a clean wipe and reflash of Mireks Android 5.

Is there any new version happening soon?
[Teclast X98 Air 3G] sunwee:
Hi Mirek

I have been using your Lollipop version for a while now. Before that I was on your excellent KitKat rom.

My observations is that the Lollipop version is prettier, has much better memory management, tablet doesn't run so hot and no gpu throttling message. HOWEVER it is also quite buggy compared to KitKat. It also has compatibility issues with some apps. And Xposed is quite buggy on it as well. I am using quite a few Xposed modules and it's causing some screen flickering especially on the notification bar.

I read that you intend to update the KitKat rom as well. I really hope so. And I hope you will bring the improvement in Lollipop to KitKat as well, such as the faster booting, better ram management, better cpu governors etc. Thanks very much
[Teclast X98 Air 3G] xyomguix:
Same here with mirek lollipop ROM but not a lot of xposed modules : only Gravity box

I was thinking about a programmer too...

Some News:

First it's is harder than I thought but the good news from what I see is that it seem possible to fix bios 1.07 and higher to work with the front camera under windows

The bug is in the ACPI table (DSDT), the ACPI table give to windows the instructions on "How to work with hardware devices" on the tablet/computer, since the information are wrong windows don't know how to communicate with the Front Camera.

Right now I'm trying different software tool to extract "ACPI table" from the bios and decompile them to edit/fix it and insert it back to the bios.

If I'm not successful going this way I will try with hacking the Windows driver of front camera to mimic as the OV2680, I'm not sure it will work this way cause maybe the ACPI tables for the 2 front camera drivers are 2 different but it could work.

Will give you you more news later about the progress ;)

-=-=-=-=-=-=-=-=-=-=-

In meantime do you have tried this "fix" for the battery drain ? :confused:

Let me know if this fix work for you please ! ;)
[Teclast X98 Air 3G] microb77:

[Teclast X98 Air 3G] Mikha777:
There is lot of chance it's the same problem or at least related. I've read that other OS like Mac or linux use ACPI tables too but since they are created mainly for Microsoft OS; when you change OS it seem that many motherboards lose devices or lose functionality since the ACPI implementation is done mainly for MS OS AKA not Linux or Mac OS.:cool:

Just to follow up on my issue getting no response in MFT when connecting X98 - I managed to get this to work on a 3rd pc. I followed the exact same procedure on the first 2 pcs and they both had the same result: nothing happened. I used the same usb cable so that wasn't the issue. The first 2 pcs were a desktop and a lenovo thinkpad. The 3rd pc was a dell venue. I even did a fresh windows install on the thinkpad but no difference. There might be usb driver compatibility issues with isoc but doubtful otherwise this would be a much wider problem.

Windows Camera and Windows Store don't work !

Hi guys . . .

Houston we have a problem:

I have the X98 3G 64GB - C5J6 - DualBIOS 2.02 rom Mirek190 v.5 and Win 10. The bios 2.02 is the item I installed last. (With Win10 already installed)

It worked fine but for two days no longer works the camera from windows (msg from Windows: "I can not open this app"). Also I can not access the Windows store, (perhaps to install a new camera).

PS: I disabled by windows the password prompt to access.

how do I fix ?

Unable to flash and/or boot anything.

I have a problem with the Teclast X98 Air II. I updated my BIOS to a somewhat strange version. The boot splash changed into a triforce logo and displayed American Megatrends under it. I could not open 32 bit operating systems anymore, which is garbage, because everything for the X98 Air is 32 bit. :mad:

I can't flash my BIOS back either, because I can't open any operating systems. Is there some way to boot the system into Android, MS-DOS or FreeDOS, so I can use FPT to flash the system again? Or can I install a 64 bit version of Android or Windows without losing my activation? Any help would br appreciated.

Some news about my work on Fixing the Bios 2.05 for the "Front Camera" problem under Windows 8/10 for Telcast X98 model HG5N HG6N C6J6 C6J7 C6J7.

I'm

very optimistic

about being able to patch the BIOS 2.05 to fix the Front camera problem with the driver not working.

I'm 90% sure to being able to resolve it quickly and I need your help

. :fingers-crossed:

I need the ACPI DSDT table for your tablet. You can dump it easily by downloading the tools from here: https://acpica.org/downloads/binary-tools

Make a Folder and extract/Unzip the tolls inside

Open a CMD window where you downloaded the tools and run:

acpidump -b

A number of .dat files will be created in the same directory, I only need dsdt.dat

Attach it to your reply and write

which tablet you use

with with which

BIOS Version

.

To help me you don't need to have a model affected by the problem

, you only need to have a Telcast X98 Air 3G or II and have Windows.

Thanks for your help and we should be able to have the BIOS very soon! :o
[Teclast X98 Air 3G] Mikha777:
You should be fine since you forget or don't know the X98 have a shell EFI 64 in the BIOS from where you can use the FPT tool ;)

You will find in the attachment the FPT tool for the EFI Shell :D

You should find the "UEFI: Built-in EFI Shell" under boot options

Here is the commands you can use inside the shell: https://software.intel.com/en-us/articles/efi-shells-and-scripting

[Teclast X98 Air 3G] Mikha777:
I never updated via EFI shell myself but I'm pretty confident it will work at the end. IMO it is one the safer way to flash a BIOS since no OS (other than EFI SHELL) run in the background) :cowboy:

After I have done some checks I have another method to suggest ;)

Let's try it... :fingers-crossed:

We will use AFU (Ami Firmware Update) the UEFI version again.

Afuefi has two versions. One is 32-bit version named 'AfuEfi.efi'.

The other is 'AfuEfix64_64' which is for 64-bit platform.

To determine which one to use, try to run AfuEfi.efi first under shell.

If you see a error message pops out then means you should use AfuEfix64.efi.

For flashing the synthax will be ike:

AfuEfix64.efi bios.BIN

Also

don't forge

t to press power button of the X98 for 15 second after the flash to shutdown the tablet.

Let us know if it work or not ! :silly:

If it did not work I have a third trick that can work...

Thanks everybody for the DSDT files/Dump, it will save me lot of time !

No need to send me more DSDT files for now, I will look at them tonight.

Like I said I'm really confident about patching the 2.02 ROM I have almost all the steps to patch it, I need just to find some more informations on how to insert back the fixed/upgraded DSDT in the BIOS file.

Worst come to Worst I will ask for some help in the BIOS Forum to know how if I don't figure it by myself.

It's the first time I try to patch a bios so it's a lot of new things for me to learn :P but I like challenge like this and hacking in general.

I will let you know when I make some substantial progress will be made :fingers-crossed:

One last Request:

Does somebody here has the ROM programmer with the clip and will be willing to test the first and be our guinea pig ? :p

There is

no real risk

other than bricking tablet and having to re-flash it to unbrick it.

Since I don't have a "rom programmer" here & if I brick my tablet I will have to wait a few weeks to order the kit or try to borrow one... and I don't want that somebody without "rom programmer" or knowledge on how to use it end bricking their tablet and lose it. If somebody is willing to test it it will speed up the project :D
