The Bios is the original 1.0. I didnt expect to need a BIOS update as I thought buying a B550 would be compatible out of the box buy I guess I was wrong.

No I didnt have an older Ryzen or know anyone that has a one I can borrow.

Any other way to update the bios?

do you have the P1.20 BIOS installed on this motherboard? If not, then you'll need to borrow a 3000 series CPU to flash to version P1.20 for Ryzen 5000 series compatibility.
