Hi, i bought the Asus C8H motherboard few days ago which came with bios version 0506. New bios version 0702 has been released and i try to flash the bios with flashback method, unfortunately no matter how i tried it just don't work, i formatted the USB drive by CMD diskpart method still failed.

USB stick must be FAT32.

Place file in root of USB stick.

File must be:-

C8H.CAP for Asus ROG Crosshair VIII Hero, also ref page 2-14 of manual.

C8HW.CAP for Asus ROG Crosshair VIII Hero WiFi, also ref page 2.15 of manual.

USB stick must be in port on rear IO which has BIOS written near it.
