Haha, well... I actually bricked my tablet as well so had to order and wait for the tools from ebay anyway. But lucky and happy that I managed to unbrick it!

Found the windows tool you mentioned, it's in the android 5.0 thread on the teclast foroum and called "Teclast Switch OS" or somethign similar. Installed it on windows and it indeed allows me to boot to android... Makes it a bit easier to switch OS, thanks for the tip!
[Teclast X98 Air 3G] benbraun322:
No problem....and I'm totally not jealous or anything :/

Are these the correct items I need to program a BIOS?

http://m.ebay.com/itm?itemId=261240580963

http://m.ebay.com/itm?itemId=151603290975

I want your help now so I can use the programmer and install the newest BIOS to fix the battery drain.

From my BlackBerry Z30 or Teclast X98 Air 3G (C8J7)
[Teclast X98 Air 3G] dagrim1:
Yup, those are the ones I ordered as well.

There is a "but" though! From what I read the winbond flash chip uses a 1.3V interface while the programmer uses a higehr voltage. Apparently this CAN fry your chip in which case you are really screwed. I only found out afterwards though, but it worked fine for me.

Also, some people mention you would have to desolder the battery in order to succesfully flash (not the case for me either, luckily). I did have to try and flash multiple times until it finally worked. So I have no clear idea of how I did it...

Also, I bricked my tablet by flashing the bios from the windows OS on the tablet itself it seems. I heard from people using the x98 toolbox to succesfully flash the bios from their computer. But again, nothing is for sure and everything can happen!
[Teclast X98 Air 3G] benbraun322:
Hmmm... never mind then won't risk it.

At least until it comes out of beta and is available for all tablets.

[Teclast X98 Air 3G] dagrim1:
Btw, the link you posted earlier is still the version without these optimizations I assume? In that case I won't re-download...

I'll flash the beta this evening and will try the rar-benchmark then as well.

Flashed and tested: 570 KB/s. CPU spy showed CPU was stuck @ 496mhz

Set min speed with ROM toolbox (which showed a speed of 0 MHz) at first which then changed to the actual speed andcran test again, result was now 1583 KB/s

Do you mean we can access NTFS partitions from Android? I'd prefer it over FAT32 due to same reason mentioned in your post.

Yes - android on teclast x 98 air handle NTFS partitions without any problem.
[Teclast X98 Air 3G] jakep_82:
I've installed Mirek's 5.0 beta on my C8J6 tablet, and everything is working quite well. I did a system only install, and everything seems to be working as expected. Even my front and rear cameras are working correctly. Overall the tablet seems to run much smoother, and I've also not had a brightness throttling which happened occasionally on the Teclast ROM.

The only bug I've noticed is that I can't install Google Plus. It was disabled when I installed the ROM, and the Play store now says my device isn't supported. I don't know if this is because I installed on top of the stock Teclast ROM, or if it's a bug in the beta. I'm too lazy to do a full re-install to test, so I'll live with it for now.

Whatever the case, make sure your USB Drive is formatted as FAT32!

Extract the downloaded files and then copy all the contents into the root of the USB Drive

How you brand name on your USB Drive. ? WinPE?
[Teclast X98 Air 3G] benbraun322:
Just curious.

You bricked your tablet and then when you went to unbrick it what BIOS did you flash using the programmer.

Did you flash an old one and then try to upgrade again to the new one or did you just flash the new one?

Bios 2.02 Build date 21/04/2015

Clean Chinese letters.

Recommeded update trough Android and choose option 2.

https://mega.co.nz/#!G88gVKAZ!mM3Lpaj1ARs4B8RNI90fSFxxztWLI1hq2haT003yJL8

Teclast switch OS in Windows.

https://mega.co.nz/#!HglAhRhY!ldGNzsm-LN8qLnqqYWxbifM8gIzh2SmagU0NWzDtxPE

Now my C8J7 unit supports hotkey switching and I hope bios will fix thermal issues and so on... Old bios was from January something. I didnt lose partitions, Android 5.0 is fine so is Windows. Old bios didnt support hotkey switching it just rebooted Android.

Sofar with new bios Thermal throttling in Android is gone!! Great!

Update took 3minutes. No data loss. So Android and Windows stay as they were.

You need Android with adb root in the tablet + windows pc with correct Intel drivers ofc.
[Teclast X98 Air 3G] T3rry1:
first thank you very much Mirek190 i appreciate all of your effort, i cant stand all of the bloat that the stock rom has on it, i will install your rom on my HG8N as soon as v2 is released.

I just want to ask, is multi users enabled in your build? i have no problem enabling it through adb if it's not, but it would just be easier if it was.

Also Mirek190 you should consider making a public folder on google drive or something that has all of your builds, that way we can see the most current without having to go through 800 pages.
[Teclast X98 Air 3G] insertvodkahere:
Are you sure you have C8J7 model? did i came only with android from factory? Could you please test if Windows has battery drain when tablet has the screen off?

And could you explain how do you used that tool to change the bios? Start Android in the tablet (android or fastboot mode?), connect it to pc, run the bat and select option 2 right?
[Teclast X98 Air 3G] sikke1:
Yes for sure, backplate has C8J7... I bought tablet semi bricked second hand. Last user had done some flashing and it had the first dual-boot bios. I have reflashed it several times and edited partitions. But this was first bios update and well worth it! Thermal warnings are gone. I have modified the cooling with extra thermal pads and will add more. This tablet was taken apart when I got it. So fairly easy to open now...

Yes you boot to android and it need to be adb rooted I think, you see from that script. Then just run the bat and dont interrupt. 2 minutes and your done. New bios, new Intel firmware. Obviously you lose your bios windows key. But already activated windows wont deactivate. I have official key, I dont care, but activator will fix if you need to reinstall.

Flashing bios will erase your bios windows key unless you follow the teclast quide for that. I assume. I dont need it.

I hit DEL with otg-connected hardware keyboard and cheked new bios is 2.02. There are some versions of Intel firmwares but didnt check my old bios so dont know didt they upgrade. I suppose they did. Least settings which you cannot see or modify are more optimized now.

Sofar nice update.

This unit had the Windows battery drain. Too early to say how it is now. But all the brightness throttlings are gone. Screen wont blink or go dimm anymore when tablet gets warm. 2minutes of Clash of Clans was causing thermal warning and force screen to dimm. Not anymore. I have previously cheked the tablet wont overheat, it runs stable under stress, bios is just more optimized now.

Hello, please tell me where can I find instructions on installing the firmware mirec190 Lollipop. Poke his nose, or please give a link
[Teclast X98 Air 3G] dagrim1:
The way it is done is roughly:

1. Prepare Intel Manufacturer Utility using the normal process (install drivers and intel manufacturer flash tool)

2. Launch the Manufacturer FlashUtility

3. If needed, adjust the values in File --> Settings (for me, X98 Air II - HG8N, they have to be the following:)

SOC device VID: 8087 FID: 0A65

Android Device VID:8087 FID: 09EF

3. File --> Open and select "flash-system_only.xml" from Mireks rom (this will only flash system and NOT repartition). If you want to repartition (only if you klnow what you're doing, serious chance of wrecking dual boot and more) select "flash-full_with_pattitioning.xml".

4. Boot your tablet holding power + vol - vol (yes, the 3 buttons together, took me a couple of shots to realize that haha)

5. plug it in your PC USB

6. The process should now start, wait until it's finished and reboot...

[Teclast X98 Air 3G] sikke1:
Just like I did in C8J7. Nice to see you also fixed the bat name FLASH, haha.

Bios is the same for all revisions.

Flash in Android with adb and before you try that make sure you understand what is adb and have drivers OK in windows.

i'm ready to test your V3 rom all weekend ;)
[Teclast X98 Air 3G] BoORDeL:
Sorry Guys please don't kill me.

Where' s the link for the BIOS installed by MIREK (i have c6j6 too) ?

Is the procedure to install it from ANDROID the following?:

If you have rooted your device,from a command prompt (with administrator rights), we give the following commands:

adb push c:\temp\fpt-tools-package data/local/tmp/

adb shell

cd data/local/tmp

chmod 0777 FPT

su

./FPT -F X98Air3G.bin

- If you have not rooted your device,from a command prompt (with administrator rights), we give the following commands:

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

Hi I've got a C8J7 and really want the BIOS also can you please explain to me how I flash in Android using adb.

Flash programator is cheap and you recover your device . It was a link a few pages earlier to it.

If was at the end of flashing passed - should be works .

You know after flash you have to keep power button for 10 sec to run device ?

Another question - with android you had ?

I was flashing on mine android 5.0 v2 - v1 should be works the same .

Safe Flash - in Android

1. Install Stock ROM 2.00 official firmware ROM is found here

2. Download Bios 2.0.2 files can be found here

https://mega.co.nz/#!G88gVKAZ!mM3Lpaj1ARs4B8RNI90fSFxxztWLI1hq2haT003yJL8

3. Unzip Bios files to Local SD

4. Turn on USB debugging

5. load the UPDATELWPi app ( it is in the official ROM )

Search for the bios files you placed onto the Local SD and search for X98_Air_3G_Dual.bin and click it and then press update

2 or 3 mins to load and Tablet will restart and reboot back into Android

But if we flash bios via IFWIUPDATE.apk i think lots of files (TXE) are not used... just the bin file. Does the bios, in that case, fix the battery drain under windows (the more annoying thing in the tablet)?

---------- Post added at 02:42 PM ---------- Previous post was at 02:25 PM ----------

who many time does the flashing bios take? ifwiupdate is showing "Upgrading, this may take a few minutes" but has been there like 5 minutes!

OKEY, IMPORTANT: with jcespi rom the IfwiUPDATE doesnt seems to work at all, it shows upgrading but does nothing, i just interrupted the process and restarted the tablet and its the same bios, it basically does nothing at all. Maybe is because in that rom the apk does not have the requisites or something i dont understand (it just creates a bios copy in the root of the tablet named com.wisky_updateifwi.bin and other named ifwiupdate_noexist.txt that does not have any contents).

Mirek, does your rom (5.0) have ifwiupdate installed?
[Teclast X98 Air 3G] Chur2Much:
I seriously don't understand people like you taking short cuts.....you are risking bricking your tablet.

So remember guys, JCESPI ROM cant be used for flashing bios! (it does not brick but does nothing). BTW im confused as mohammad_skiller said he flashed the bios using the "lite rom" that i pressume is the jcespi one and it worked for him. I think the problem is that in this rom ifwiupdate isnt a system app, and because of that it dont have the requiered permissions to flash the bios.
