I your place
@Cosmin88 i wouldn't argue
@eidairaman1
More than thin i strongly suggest you to use as the only method to flash the BIOS files the CMD opened with admin privileges and from there using amdvbflash.
If you do not know how to do that write here and i will support you step by step
So you must use the CMD flash procedure:
Save the BIOS file (one at a time of course ) i provided in the amdflash folder and rename it as RX470.rom
open CMD with admin privileges
Use CD command to enter atiflash folder (directory)
use the following command to flash:
amdvbflash -p -f -fa -fs RX470.rom
after BIOS is flashed a message will appear to restart computer
Kepp us informed how it went
