Prerequisites for Using USB BIOS Flashback
Before diving into the process, ensure you have the following:

Step-by-Step Guide to Using ASUS ROG USB BIOS Flashback
Follow these steps to update your BIOS using the USB BIOS Flashback feature:
1. Download the BIOS file: Visit the ASUS website and search for your motherboard model. Navigate to the “Support” or “Downloads” section and locate the latest BIOS file for your motherboard. Download the file and save it to your computer.
2. Prepare the USB drive: Format the USB drive to FAT32 and ensure it’s empty. Rename the downloaded BIOS file to “**ASUS.CAP**” and copy it to the root directory of the USB drive.
3. Connect the USB drive: Power off your computer and unplug it from the power outlet. Connect the USB drive to the dedicated USB BIOS Flashback port on your motherboard. This port is usually labeled with a “BIOS Flashback” symbol.
4. Connect the power supply: Connect the power supply to the motherboard’s power connector. You can use a power supply unit (PSU) or a dedicated power supply tester.
5. Press and hold the BIOS Flashback button: Locate the BIOS Flashback button on your motherboard, usually near the USB BIOS Flashback port. Press and hold the button for about 3-5 seconds until the LED next to the button starts flashing.
6. Wait for the update to complete: The LED will continue flashing while the BIOS update is in progress. This process can take several minutes, so be patient and avoid interrupting the update.
7. Disconnect the power supply and USB drive: Once the LED stops flashing, the BIOS update is complete. Disconnect the power supply and remove the USB drive from the motherboard.
8. Power on your computer: Connect the power supply and turn on your computer. The new BIOS version should now be loaded.
Verifying the BIOS Update
After completing the BIOS update, it’s essential to verify that the update was successful. You can do this by:
- Checking the BIOS version: Access the BIOS setup menu by pressing the designated key during boot (usually Delete or F2). Look for the BIOS version information in the main BIOS screen.
- Checking the ASUS website: Visit the ASUS website and check the “Support” or “Downloads” section for your motherboard model. The latest BIOS version should be listed on the website.
Troubleshooting Common Issues
While USB BIOS Flashback is a convenient feature, you might encounter some issues during the update process. Here are some common issues and their solutions:
- The LED doesn’t flash: Ensure that the USB drive is properly formatted and contains the correct BIOS file. Check if the USB drive is connected to the designated USB BIOS Flashback port. Verify that the power supply is connected to the motherboard.
- The update fails: Check if the BIOS file is compatible with your motherboard. Ensure the USB drive is not corrupted or damaged. Try using a different USB drive.
- The computer doesn’t boot after the update: If the computer doesn’t boot after the BIOS update, try clearing the CMOS by removing the CMOS battery for a few minutes. You can also try booting into Safe Mode and reinstalling the operating system.
Beyond the Basics: Advanced Tips and Tricks
- Using a dedicated BIOS Flashback tool: Some ROG motherboards come with a dedicated BIOS Flashback tool that simplifies the update process. This tool allows you to select the BIOS file and initiate the update without manually pressing the BIOS Flashback button.
- Using a bootable USB drive: You can also create a bootable USB drive with the BIOS file and update the BIOS through the BIOS setup menu. This method is more flexible but requires booting into the BIOS setup menu.
- Back up your BIOS: Before updating the BIOS, it’s always a good idea to back up your current BIOS version. This allows you to revert to the previous version if necessary.
