Question no signal after bios flash

[Elements6007]

so i bought a RX 570 used and the seller told me to do a bios flash.... and i didnt know any better at the time so i did it and after a restart it gives zero signal.... what do i do? is it totally bricked?

I assume that you mean a firmware update for the RX570 and not a motherboard bios update?

No real answer, but what I would try would be to make a computer bios change to boot from the motherboard GPU output so that you can start it up and then attempt to reflash with a proper GPU firmware that is downloaded from AMD.

i meant i flashed the video bios........ so if i use my on board graphics i should be able to re flash it?
