HD 7770 brick: blocking bootup (video card bios)

[Blooker]

Hey guys, I have bricked my HD7770's VGA BIOS on flash attempt.
Now I know how to recover such a thing. But, the thing is, the card blocks the PC when inserted. It will not boot up/PC will not even go through the system BIOS when the card is inserted.

It does not block when the power (gpu 6-pins) is out of the card, but this way the card wont be recognized so i cannot flash and recover the videocard's bios.

How can i re-flash my videocard if the card blocks any (tried several) PC from booting with it inserted? Do i need to have a electronic device to flash the chip or is there a way around this?
It seems that the GPU bios has a programmed feature to prevent booting a PC with the damaged video bios on it...

sounds bricked to me. not sure what you can do at that point. sorry 🙁

possibly plug it into a secondary pci slot and run the system off the onboard graphics or another gpu. that might work

They were helpful, you can't boot to a damaged card, which means you need to boot to a non-damaged card. The only way to flash the ROM of the video card now would be to remove the chips off the card, and program them using a machine which would probably cost you 10 times more than a new even high-end video card.

Not getting the answer you were hoping to get is not cause for thinking it's a bad answer. Dead card = no boot with it. No way around it.
