Hey I recently tried flashing my new Gigabyte Aero 4070ti OC to a 4080 with the unprotected nvflash given by OCN, i flashed it to a different 4070ti at first, then decided to go to a 4080 because I was thinking it was gonna work, I restart my pc and it just continuously restarts with no boot on the monitor. Anyone have any tips?

For starters, do you have any other card you can boot your PC with? If yes, do your motherboard have two PCIe slots, with enough clearance so you could turn your pc on with both installed?

I don't wanne be rude, because everybody do mistake, but next time you should ask before :toast:
 
This is completely recoverable, like worst case you can get someone to pull the VBIOS chip and flash it directly, and it probably won't come to that... But why? It would never work. It's not like you saw someone do this successfully (or if you did it was a cruel hoax), and we're dealing with a brand new card, not something you got for $20 from a garage sale. Why?
 
Might have to buy a chip programmer and flash it back.

Would it be possible to reflash it if the system boots using another card alongside?
 
why would you crossflash different dies and SKUs?
this does nothing except of bricking the card.
 
Does the 4070 Ti not have a dual bios?
 
What drove you to this madness?

I've done this before with older 4 series. Haven't tried in years. Like 13 years to be exact lol.

I remember correctly. I had to command line nvflasher, select the correct PCIE slot and blindly flash it. The card won't show up, but if it has power you might be able to brute a flash to whatever is in that slot.
 
Yeah, nvflash will index each GPU. Likely looking at booting with another card and doing a nvflash -6 AD104.rom here. If the GPU used to boot is also from Nvidia, nvflash will enumerate them, you can bring it up with --list and then assign the index eg. nvflash -i1 -6 AD104.rom
