Hi,

I'm having some issues since i upgraded my bios (generally fan problems)

Is there any way to pass under 2.00 ? Since i'm in version 2.28 and i would like to go 1.01 (the first version for this model)

Here is the link to the 1.01 bios

Already tried by downloading it and putting the VAGV101.fd file on a Usb stick, the flash procedure started but it cancelled immediately (since it doesn't want to pass under 2.00).


Thanks !

Ok friend,
we can rollback to v.1.15 and then reflash the 1.10 Original version !
If You agree with me use this tool run It as Admin and upload here th result file :

Ok friend,
when svl7 tool say ready to flash Hit Enter It means that can bypass the Write Protection so
hitting enter will reflash Bios Mod !
In your pics 1st svl7 is running and into 2nd not !
So have You hitted ENTER key and gone further ?
Let me know
Regards

P.S. if We cannot bypass error 28 only SPI Programmer can do the job !

Hi!

Well the first images says me to press Enter, which I did, then it shows me what's in the second image.

If I press enter again (2 times so) it's exiting the .bat file

Hi friend,
your Eeprom is Write Protect = Error 28 and only an HW SPIPGM can rewrite
your old Bios or a Bios Mod !
