Question Black screen after updating BIOS on Asus Prime B450M-A for Ryzen 5000 ?

[Cheese Dripper]

Hi all, I've attempted to update the bios on my Asus Prime B450M-A to the 4202 version to support a Ryzen 5 5500, however upon completing the update I have no display whatsoever. The CPU used in the build for the process is a Ryzen 3 3200G, working fine just before. I'm not entirely sure what to do at this stage, nor do I see anything relating to BIOS flashback available for this board.

I did follow the correct procedure for updating, went through the bios, using Asus EZ Flash, USB stick 32gb Fat32,

Update worked up until restart, cannot recall the previous bios version

If anyone can help with this that'd be awesome, this is causing me quite a bit of stress at the moment
Thanks

Are you saying you now get no display with either the 5500 or the 3200g?
Have you tried booting with 1 stick of RAM in the 2nd DIMM slot?
Have you tried booting with no drives connected to see if you can get into the BIOS?
