Anybody?

No one running bios 2.02 on teclast air 2 HG9M?

[Lasse]

I am running the latest 4.2 ROM and the 2.02 bios.
I first upgraded the bios then I flashed the ROM.
It works.
I have had quite a few apps crash though. I will probably move to the new official v5 ROM.

Hi Lasse,

do you own the Air 2 HG9M? Can you explain a little how you upgraded the Bios and the Rom?

thx Levd

I do own the Air II HG9M and I upgraded from 1.80 to 2.02.

I did the upgrade via Windows, and it worked flawlessly. I’ve even updated to Win 10 lately. Updating the BIOS didn’t have any adverse effect on the tablet (no partition loss of whatsoever) but I did a backup of the data, extract the win 8.1 product key, and prepared the Teclast “restore set” just in case.

Hi Luca,

Did you upgraded with the intel tool from Windows?

I have a c5j6 so it may not be same but I completely upgraded my tablet on the weekend.

First I backed up my win8.1 key and installled the 2.02 BIOS using this guide:

Then once that had worked I upgraded to Windows 10 and that worked.

Finally I upgraded from stock ROM to Mirek 4.2.2 and that worked using the install.bat file and wipe Data option (not partiton).

All partitions and OS’s worked fine.

After doing much reading I think it is important to upgrade the BIOS to 2.02 before upgrading everything.

Hope this helps

Which BIOS must I download here ? I don’t see a BIOS 2.02 for the HG9M
