ASRock has released VBIOS updates for ten Radeon RX 7000 series graphics cards, joining Sapphire and GIGABYTE. The new firmware, version 1.0.5, was made available on ASRock's support pages on October 29. However, multiple users are now reporting that their ASRock GPUs have been bricked after updating the firmware.
The issue occurs when users start the ASRVBFlash 1.0.5 utility; Windows begins its reboot sequence, and the system then fails to boot. A solution to this problem appears to be reinstalling an older VBIOS, which some users have downloaded from TechPowerUp's VBIOS hosting. ASRock is reportedly removing VBIOS version 1.0.5 from its download pages, but it is still accessible through FTP connections, indicating that it is only temporarily hidden.
Those who haven't updated their VBIOS and have a Radeon RX 7900 XT/XTX GPU should be more patient. If readers recall, most of AMD's add-in board partners issued new VBIOS security updates for Radeon RX 7000 models as a security fix, but the original vulnerability remains unknown.
