[Teclast X98 Air 3G] astromark:
Air 3G - C5J6 - Flashed to 2.02

Ok, I've taken the plunge on my Air 3G. Mine is the C5J6 version, 64GB dual boot. BIOS reported before flash by CPU-Z as 5.6.5 dated 01/16/15. (We know the version is reporting wrong but date correct.)

It worked - so for others here's what I did.

I did it in Windows on the tablet itself. Here's how I did it.

I got the BIOS from Techtablets http://techtablets.com/teclast-x98-air-3g/downloads/

and grabbed the file called: X98 Air 3G Flasher Bios 2.02 - Works On 100 % On C5J6, C6J6, C8J7 (13.3 MiB)

From there I extracted the bios file "X98_Air_3G_Dual.bin".

EDIT See post below - it is also in Mireks repository.

I installed IFTP on the tablet http://www44.zippyshare.com/v/jFaJlrjM/file.html

and followed the instructions below

When I made a backup of the current BIOS I copied it to the SD card -

no point it being stuck on a bricked device!

I ran fptw and it took about 2 minutes. As it started I got a yellow error: PDR region does not exist. At the end I got a green message: FPT Operation Passed.

I gave it a minute or two and powered down. It took a heart-stopping few more seconds than usual to power up again!

BIOS reported after flash by CPU-Z is 5.6.5 dated 4/21/15 - version number apparently different but date has changed, so presumably it has updated.

EDIT: Yes, I looked in the BIOS setup itself and it reports 2.02.

Thanks to Wootever and Mirek.
