I'm having a tough time updating the BIOS on my PRIME X670-P WiFi motherboard. The current version I'm on is from 2022 (0421, released on 8/19/2022). I've tried a bunch of methods like using different USB drives, the EZ Flash Utility, and even BIOS Flashback, but nothing seems to work. I can boot into Windows without any issues, but I noticed that the oldest BIOS versions available on the ASUS website are 1409 and 1410, both from 2023. Does anyone know how I might get a BIOS version that's newer than 0421 but older than 1409?

Are you sure you're checking the right website? The page for the PRIME X670-P shows a version 3287 from October 2025. You might be missing it if you overlooked that.
1. That's the X670-P. My board is the X670-P WiFi, which has its own dedicated page.
2. Even in your link, it only shows 1410 and 1409 from 2023.
3. I can't install any version, not even the latest.
