Your issue definitely sounds like heat induced hardware failure, especially the part where Windows locks up and you can't find a thermal event in event viewer. Sounds like the heat is killing the processor even before the temperature alarm can shut the processor down. Unfortunately, this tablet is not known for it's heat dissipation properties. The thermal engineering design certainly won't win any awards. Teclast could have spent 20 cents more per tablet in manufacturing (on thermal grease or a heat sink) and ended up with a much more reliable tablet.

Yeah, surely I can dump the bios as long as I find enough information how to do it. I´m going to install windows 8.1 into it briefly, just looking for instructions how to do it. I have to root first? Do I need an usb keyboard if I want to install a vanilla 8.1 from an image? Hit me with a PM on how to do the root/win process
[Teclast X98 Air 3G] BoORDeL:
Perfect Robusto.

it is simplest to dump bios from Windows.

Just let us know when u r readyu ;).

Thank you mate
[Teclast X98 Air 3G] robusto:
Np, so you recommend me to install windows first, then dump the bios from there?

Do I need an usb keyboard if I want to install win8.1 from other image than the teclast one? If I do, then you guys have to wait ´till tomorrow because I dont have one within my hands today.
[Teclast X98 Air 3G] jacfry:
If you are on Android right now you need to flash different bios to install windows. This bios image file is what we are looking for.
[Teclast X98 Air 3G] robusto:
"this bios image file" referring to the one after windows installation? Sorry, I´m a total beginner in this but I do my best
[Teclast X98 Air 3G] jacfry:
It's in the procedure above (to be executed still under Android). Third post in this thread. X98Air3G.bin is for C6J6. Yours is C8J7 and we are not sure if you can use it.
[Teclast X98 Air 3G] abo.adam:
hello , i'm trying from yesterday to download the file but i can't , did you download it ? please if yes share it on mega
[Teclast X98 Air 3G] robusto:
OK, so basically I should not risk it and flash it right now, otherwise I might end up with a paperweight, right?
[Teclast X98 Air 3G] jacfry:
Unfortunatelly that's the possibility. If it won't boot then the only way to restore it would be to flash the right bios using SPI programmer. That requires opening the case and in my case unsoldering the eeprom chip. So it's the risk I have to warn you about. Some of us having C6J6 devices running windows (including me) are willing to take that risk and try to flash the newer bios from devices which are not affected by our problems. So what we are looking for is someone with the newer tablet running WINDOWS to dump the bios and share with us
[Teclast X98 Air 3G] robusto:
So you had to unsolder it? It has happened to people before that the flash is unsuccessful because of the different "builds" i.e. C6J6 vs C8J7?
[Teclast X98 Air 3G] jacfry:
I had different problem, but had to flash the bios outside the device. I didn't hear about anybody trying to flash C6J6 bios (the one that is published) to C8J7 device, so I don't know what the outcome would be. Maybe just some minor problem but total brick is also possible
[Teclast X98 Air 3G] mirek190:
Still downloading - 92 % :p
[Teclast X98 Air 3G] robusto:
OK. What is the probability that they will release C8J7 bios, any idea?
[Teclast X98 Air 3G] mirek190:
Where I can find newest android bios for x98 air 3g ?
[Teclast X98 Air 3G] HDtracer:
Dont know if you have his sorted out or not. Have you changed the system language? The launcher changes to 99% English when you do.

If you go to main android settings/ keyboards and select pingyu keyboard you can uncheck all the chinese language options for the keyboard.

In the actual keyboard there is a settings icon on the lower left and in there it lets you select default language/input style/keyboard look etc.

The fix for play store is on the first page.

The standard Teclast launcher doesn't rotate in the home screen either from memory.

the thing i wanna ask is :

Now he has the newest Air 3G right? (C8J7) but preinstalled as Android... This means the bios that tablet has only for Android, not for Windows.. so there is not possibility to dump the windows for us, am i right? :confused:

So for the bios we want, we need the newest device (C8J7) with preinstalled Windows and no showing issues such camera,touchscreen and screen refresh rate(48hz lock) and dump its bios..
[Teclast X98 Air 3G] robusto:
Exactly, you got it correct. Its preinstalled with Android.

No, unfortunately for 2 reasons.

1. init.rc originates in the boot.img.

It is copied to the system root from the boot.img, so if you changed it, the next time your system boots, it would just overwrite the changes.

2. You are no doubt missing .other files as well, such as /system/bin/switchtowindowssystem.

However, this does explain why OsSwitch.apk is not working for you. It appears now that OsSwitch from Android to Windows has 2 dependencies to work.

1. Must have BIOS 2.02 flashed.

2. Android image must have some supporting infrastructure, such as boot2windows service definition and switchtowindowssystem binary.

I am pretty sure that all of Mirek190's ROMs, both KitKat and Lollipop contain the required infrastructure. I will double check here in a sec.

I couldn't agree more on this seized. Who hasn't struggled with finding reliable instructions for the myriad variety of procedures that you might need to do to your tablet. Compound that with all the different models of tablet and the inconsistent "instructions" and you can see why new visitors ask for instructions on a variety of things in the open forum.

I have also found that there is a lot of dated information and even disinformation posted here.

However, XDA's rich formatting and media support allows for the flexibility of setting up detailed instructions with attached files and screen captures and allows the poster to edit the post as needed in the future. I notice that a lot of visitors who ask for instructions on something are referred to a video. I have always preferred concise written instructions, so I can see in 1 glance what I need to do. I am hoping to create some current, up to date written instructions for common procedures that are applicable to all models of Air II and 3G, with per model specifics where necessary. I will create a "Ground Zero" post with links to all the currently documented procedures.

mirek190_rom_v4 - android 4.4.4

Teclast air x98 3g ( c5jx, c6jx, c8jx , c9Jx, air2 )​

* ability to flash only system ( data and partitions are not touched ) or full flash.

* system partition 1 GB instead of 1.5 GB -default but you can change it.

* cache 100 MB instead of 1024 MB - is completely enough I tested but you can change it.

* data partition 27 GB instead of 25 GB ( 32 GB variant ) - I added other partition tables for data like 1 , 2, 3, 4, 5 ,6 ,7 ,8 ,9 , 10,15,20,30,40 GB , only android , only windows or default.

* fully rooted

* removed all Chinese programs

* busy box

* init.d

* zip alignment

* deodexed

* changed navigation buttons to looks better

* resided navigation bar

* removed vol buttons and screenshot button from navigation bar - screenshot you can make pressing vol - and power at the same time.

* bold fonts on system bar - fonts looks better

* lower min brightens

* microphone gain fix

* clock on the middle of the status bar

* changes in Buildprop for performance.

* optimizations in Framework

* added. Google services, Google play, YouTube , etc

* adblock ( need root )

* new MxPlayer with codecs that are able to run everything.

* resolution changer ( need root )

* ViPER4Android FX - need root now sound is really good and noisy [emoji14]

* default adb and developer options are on after flash

* Stock browser no searching on Chinese websites anymore !

* Apex launcher

* Xposed and addon Gravity Box - you can customise battery , power menu , etc

* Gpu-fix - a little underclock ( 590 mhz ) to prevent freezes - you can easily change it in ( /system/etc/init.d/gpu-fix ) or remove it to get full speed.

* read and write fix for memory card

* no more throlling message anymore .

* optimizations for :

internet speed tweaks

GSM/3g tweaks ( for 3g air only )

WiFi tweaks

vm management tweaks

kernel tweaks

tweaks in kernel ramdisk

battery tweaks

optimisations, tweaks for ETX4 partitions

governor and I/O tweaks

tweaks for memory ( RAM ) and lowmemorykiller - heavy multitasking works nice !

and more I don't remember

IMPORTANT​

I recommend ( MUST ) wipe data because I changed a lots of things in virtual machine and not all optilimaziations will be work ( no all apps will be visible ) propely until you make data format.

I created xml file called flash-system_only_WIPE_DATA.xmll for it !

Ps. I added new method of flashing via adb or fastboot ( partitioning not working jet in this method ) now you have 2 ways of flashing :

- plug device via USB ( in android or droidboot ) and run proper script.

- or use MFT - intell manufacturing tool .

Ok guys im stumped, in a powercfg batteryreport (or any other battery reporting for that matter) my "design capacity" only shows as 14,400 mwh, but the full capacity is 31,160. Does anyone else get this? i have a feeling its messing with my battery charging, and i did use a bleepin faulty usb meter to charge it a few times, of course i found it was faulty later, its like it has a horrible connection and only lets less than half of the true amps through. Anyways heres a ss of what im talking about, can anyone shed some light on why its reporting this way?

If anyone wants to check theirs just swipe in on right, type cmd, right click run as administrator on command prompt; then type:

powercfg batteryreport

after that you just navigate to the file it says, should be system32 and an internet link called battery-report.

So yea anyone know why its only showing like half the capacity as design capacity?
