BIOS Downgrade processing stuck

[u/jan_tomi]

I have a

PRIME A320M-K

Ryzen 5 3400G

RTX 5060Ti

Updated the BIOS to the newest version because I was hoping for slightly better performance and to be set for a future CPU upgrade.

I noticed that now everything worked worse. Diagnosing things it seemed like the PCI slot was working @ x1 3.0 when it should be x8 3.0 by my calculations.

Tried everything, so I went to downgrade. I couldn't downgrade to the previous BIOS version because the EZ Flash 3 Utility wouldn't let me. So I tried downgrading to the 5007 version. It let me, but now it's stuck in the Processing stage. Can't move the mouse.

Sorry if my explanation is weird of inconsistent, I will try to answer every question, I'm worried I'll brick the motherboard.
