I recently purchased two bricked Diamond Multimedia RX 580 8gb cards. I have tried just about every method, but can't seem to get them working. I believe the problem is the RX 590 bios (shows it in device manager and gpu z), as both of them have the same problem. I have tried using DOS, jumping pins 1/8, and atiflash on windows. Atiflash always displays "cannot read rom" on windows, and DOS doesn't allow -f command, and atiflash -i fails the romtest. Any ideas on how to get it running?
