USB BIOS Flashback the Quick and Easy way

Everyone I know has this fear of updating the Motherboard's BIOS, thinking I might brick it and the motherboard will then become useless. Even I had this fear of updating my Asus ROG x570 Crosshair Formula VIII motherboard, for those who don't know, this motherboard is about 600 USD, So yeah if I brick it, its a major investment down the drain.

Anyways, coming to the topic, USB BIOS Flashback for ASUS or similar features on other Brands like MSI's "Flash BIOS" , ASROCK's "BIOS Flashback" and Gigabyte's "Q-FLASH Plus", is probably the most fail-safe process for updating the Motherboard's BIOS.

This feature mainly comes in handy when it comes to updating the motherboard's BIOS to support and boot the Latest CPU's when you don't have the older compatible CPU at hand. Now let's see how we can do this.

How to Flash your BIOS via USB

You can watch this 1-min video detailing the steps, or just scroll on below to see the detailed step by step in written form.

Note: Before you start ensure your power supply will not be interrupted


Download the latest BIOS for your motherboard. You will find this on your Motherboards Support page, at your motherboard's product website.


Extract the file to a folder and either manually rename the BIOS file (if needed) as per the instructions shown on the download page. (for ASUS run the Renamer executable).


Format a USB drive/stick (at least 8GB or higher) to the FAT32 file system, and transfer only the BIOS file into it.


Power up the Motherboard by connecting the 24pin cable from the PSU to the Motherboard. Note: CPU, RAM and GPU need not be required to be set into the motherboard.


Insert the USB stick containing the BIOS into the marked USB port at the back of the motherboard


Press and hold the BIOS Flashback (Q-Flash on Gigabyte boards) for 2 to 3 secs till you see it blinking, then release.


Sit back and relax, you will see that it will continue to blink while the BIOS is being updated in the background. If your Motherboard has an OLED display it will display the stages of the update. This process will take anywhere from about 3 to 7 mins.


BIOS is updated when the BIOS flashback button stops blinking.

That's it you are done, now it is safe to remove the USB stick.

The motherboard is all up-to-date and supports any new compatible CPUs.
