The BIOS isn't updating properly.
The BIOS isn't updating properly.
You're experiencing issues updating your BIOS on the ASUS Prime X470 Pro. The process seems to stall around 25% and then restart, regardless of method—USB or online. Since you recently upgraded from version 5007 to 5406 without problems, it's possible the new BIOS version isn't compatible or requires specific steps. Consider checking the official ASUS support documentation for your model, verifying the correct BIOS version, and ensuring your hardware meets the requirements before proceeding.
I reset the CMOS before updating the BIOS. This ensures everything resets to its original state. I've done this for years and it consistently functions correctly.
