RX 580 2048SP with corrupted BIOS
Hello everyone, I have an RX 580 2048SP VEINEDA and I wanted to change its BIOS because it was a mining BIOS. I watched some YouTube videos on how to do the process and followed the steps. I backed up the original BIOS using GPU-Z and saved it on my pendrive.
I managed to successfully flash a different BIOS, but the problem was that I couldn’t get my monitor to run at 165Hz in Windows at all — neither in AMD Adrenalin nor anywhere else. That’s when I thought about restoring the original BIOS that I had saved with GPU-Z.
I ran the commands correctly, but it wasn’t working and it showed a “BIOS invalid” error. Then I loaded the original BIOS file into Polaris BIOS Editor, and it showed a warning: “Checksum is non-valid! Please save the file to fix.” From what I understood, something was wrong, but I noticed it said “Save to fix,” so I did exactly that.
I didn’t change anything — I just opened the original BIOS file and clicked save. Then I tried flashing it back to the graphics card using CMD. Everything went fine in CMD, and at the end it asked me to restart the PC to complete the BIOS update.
After restarting, the PC no longer shows any video output. The keyboard doesn’t show Num Lock activity, and the SSD light doesn’t blink either — meaning it’s not even booting into Windows. I don’t have another graphics card, and my processor doesn’t have integrated graphics.
Is there any way to fix this, or is it not possible anymore?
