ASRock Radeon RX 7900 XT/XTX VBIOS Update Bricks Some Cards

When ASRock joined the group of AIBs patching Radeon RX 7900 XT/XTX GPUs late last month, everything seemed fine for a few days. However, multiple users are now reporting that their ASRock GPUs have been bricked after updating the firmware with the latest VBIOS. ASRock has released VBIOS updates for ten of its 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 and includes updates for the RX 7600 XT Challenger and Steel Legend, RX 7700 XT Challenger, RX 7800 XT Challenger and Steel Legend, RX 7900 XT Phantom Gaming (including the White version), and the RX 7900 XTX Phantom Gaming and Taichi, along with the Taichi White.

However, several users have reported that VBIOS version 1.0.5 bricked their cards. 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. This can help if your PC is bricked by any VBIOS update, and you need to find an older version to flash. Read full story
