Hello, I have an Sapphire RX480 4gb on which i bricked one of the two bioses. I tried to flash it because on boot it would sometimes show black screen and ocasionally garbage mess. I do not have a copy of original bios, I also dont have integrated graphics (Intel i5 9400F). Is there a way to fix the second gpu bios? Many thanks.

What process or procedure did you use for the attempted flash?

What original version and what new version?

Source?
I believe the versions were the same. I just wanted to fix my boot. Downloaded from techpowerup.com here: https://www.techpowerup.com/vgabios/186343/sapphire-rx480-4096-160906

and i used this tool: https://www.techpowerup.com/download/ati-atiflash/

at the end of the flash, it said flash completed succesfully. After restart one of the bioses died.

In the event of 1 bios being bricked:
-log in/sign in using the working bios
-download the original bios, or at least one confirmed compatible with the card
-flip the switch to the borked bios while the PC is running
-flash bios
I think you're then prompted to restart the PC afterwards.

1)I don't really see a reason to do that... more importantly is that you get dual bios working again.
So... your call whether to use the same bios twice or not.

2)Would need to see the files in question to know for sure.
