i recently flashed a vbios in my gpu and now it's not showing display. i tried to find out what's wrong and i found out that the vbios file had the voltages set to like 60000mv. that's what caused the gpu to not get display. then i tried to flash it again with the safe steps in amdvbflash/atiflash. now i can't flash it and it show's failed to read rom. what do i do to fix this issue? ( Sorry for my bad english hope you got my point )
