Hi, I'm using a Ryzen 5 1400 processor on the B450M Pro4-F R2.0. The processor is running fine but I can't update the BIOS of it. No matter what I do the BIOS file won't show during the instant flash mode. This is not the first time I updated motherboard BIOS, so I'm not a newbie. Done literally everything, FAT/FAT16 whatever but the BIOS file just won't show. The motherboard come with the 2.80 bios version. There r already 2 more version uploaded in the site but none of them r showing during the Instant flash mode.

Pls, can I have some help regarding this issue?

Yes, of course I unzipped the files. No matter what I do it just shows "no image file detected"

1) What tool are you using for the bios update
2) try using the usb ports in the back
3) check in the bios to see if the bios sees the usb flash drive

Ok, I think I now know what is the actual issue. This is super f... weird. The board I bought is clearly say "B450M Pro4-F R2.0", even I checked on the marking beside RAM slot, it says B450M Pro4-F R2.0". But the bios flashed from factory is actually the regular "B450M Pro4-F". In short, I have a "B450M Pro4-F R2.0" board with "B450M Pro4-F" bios.

The factory bios it shipped with is v2.80. This is why it can't detect the latest bios from R2.0 because the last bios of regular Pro4-F is 2.80.

I will post some screenshot later.
