I am trying to flash my gtx 970 with a custom vbios, but nvflash states that there is a gpu mismatch. I renamed the file to GM204.rom, but it still giving me the mismatch error. Please help if you can, thank you.

the name doesn't matter. it needs to be the correct BIOS for your card.

if you have a custom PCB card, AFAIK, you need to find the correct BIOS for it. a normal one won't work.

I tried every nvflash that has support for the 970m, still no luck. What could the issue be?

update- I think the vbios is the problem, I extracted my stock vbios and flashed it with the same nvflash that would not accept the modified version, and it was immediately verified.

So protection is disabled? Following good instructions?
