I apologize for this post if it addressed somewhere else. I have found several threads, with many solutions. None of them seem to work for me, so I thought I would post my own experience on here. I started out trying to flash the bios on a RX 580 x gaming edition video card. I backed up the original bios on atiflash, and I used polaris bios editor to make adjustments to the original backed up bios. When I went to flash (via ati flash in windows) the video card, I received an error message saying that the bios can not be deleted. I reset atiflash, and started getting "error reading from rom" message. So, my search began. I have tried to run atiflash through command prompt with administrator access, I have made a dos bootable usb drive to run atiflash, I have deleted the drivers, reset windows, and I can not do anything to load the bios in atiflash. I have unlocked the rom inside ati flash, and received a message saying the rom is unlocked. still get the same error telling me that the file can not be found, referring to whichever rom I try to flash. When I go in to dos, it tells me the adapter is not found. I have tried the pins 1 and 8 trick, but nothing changes. I'm not sure what I'm missing, or doing wrong. Any ideas or help would be greatly appreciated. Thanks.
