BIOS Flashback is not working properly due to improper USB flash drive connection, 

BIOS file name error, or incompatible BIOS file format. If this happens, restart the 

system.

3.  BIOS updating poses some risks. If the BIOS program is damaged during the updating  

process and the system fails to reboot, please contact your local ASUS Service Center 

for assistance.

USB BIOS Flashback allows you to update the BIOS without entering the BIOS or operating 

system. Just connect the USB storage device containing the BIOS file to the USB port, press 

the BIOS Flashback button, and the BIOS is updated automatically.

save it to the root directory of your USB flash drive.

Press the USB Flashback button for three seconds until the LED flashes. The LED 

goes out when the BIOS update is completed.
