MSI AMD B550 Pro Socket AM4 ATX

Flashback bios option did not work for me. I flashed this MB around 18 times and nothing. Everything powered on per the normal but MB never read the CPU. I tried dozens of USB drives, which made the whole flashing process incredibly frustrating. I tried this with two MSI MB's and nothing worked for me. Flashing process was successful every time but for some reason CPU was never read. Returned got my money back and never looked back. The fact that I spent more money on this MB and it arrived used/not sealed and missing items out of the box. Not sure if my issue with flashing was actually a bad MB. Went with ASUS B550 ROG STRIX GAMING F which worked out of the box for the newer Ryzen 5 5600G CPU.
