Colorful BATTLE-AX B650M-PLUS V14 — BIOS 1012 to 1023 Update Failing

I built my first gaming PC in April 2026, and I’m currently running BIOS Version 1012 on my Colorful BATTLE-AX B650M-PLUS V14. I’m trying to update to BIOS Version 1023, but I haven’t been able to get the update to work.

Here’s what I’ve tried so far:

• Current BIOS: Version 1012
• Target BIOS: Version 1023
• Motherboard: Colorful BATTLE-AX B650M-PLUS V14
• Reformatted my USB flash drive to FAT32
• Copied the BIOS file to the USB drive
• Plugged the USB drive directly into the motherboard
• Tried the normal/manual BIOS update method through the BIOS
• Also tried BIOS Flashback
• For Flashback, I used the designated Flashback USB port and followed the instructions provided by Colorful
• However, the Flashback LED never started blinking
• I left the system for 50+ minutes, but there was no indication that the BIOS update had started or completed

As far as I know, I followed the instructions correctly, but I may have missed an important step.

Could someone with the same motherboard or experience with Colorful BIOS Flashback help me figure out what I’m doing wrong?

I’m particularly wondering:

1. Does the BIOS file need to be renamed to a specific filename for Flashback?
2. Is there a specific USB flash drive size or USB 2.0/3.0 requirement?
3. Does the USB need to contain only the BIOS file?
4. Is there a specific USB port that must be used for Flashback?
5. Is BIOS 1023 definitely compatible with the BATTLE-AX B650M-PLUS V14, or could I be using the wrong BIOS file?
6. Are there any additional steps required before using BIOS Flashback?

I’d appreciate any advice from someone familiar with this motherboard. I’d rather make sure I’m doing everything correctly before attempting another BIOS flash.

Thank you!
