Razer Blackwidow V4 Pro 75% Corrupted by Synapse 4

Long story short, my PC was reformatted and I made the poor choice of installing Synapse 4. This is the 2nd time I’ve (accidentally) installed Synapse 4, resulting in my keyboard becoming glitched:

I’m now in the exact same position as I was before. However, my “FIX” doesn’t work. I must’ve accidentally stumbled across a keybind/key that allows you to bypass the firmware updater tools “You already have the latest firmware restriction” which I now can’t seem to figure out.

 

Has anyone been able to reliably force a firmware re-flash?

My “F” and “L” switches have now started to fail, too. What a mess. I’m sure it’s firmware related, but there’s no way to re-flash the keyboard and the last update for the firmware was last year.
