That’s of no use on this one. The firmware was updated and rolling back isn’t going to change that. I take the same approach. Had to restore with a clone after the March security update. Got my display and ports working again but every day I still get BridgeOS crashes. It’s useable.These days I clone my system partition to an external drive and verify that I can boot from it, BEFORE I install ANY of Apple’s system/security updates. Yes this extra step it’s a pain. But nowhere near as painful as dealing with Apple’s recent buggy updates.

My mini never shuts down or sleeps, its our media server. Still crashes at least once a day after the March security update.Hello -- I have the same problem as I wrote, but yesterday from the Apple Discussions group someone sent this suggestion, which has worked for me to keep my Mac from crashing / restarting / shutting-down 2-6 times per day-- this suggestion prevents the Mac from going to sleep and it seems to be that it is in the sleep mode when it crashes or restarts:
He wrote: I have not had the issue with my machine randomly restarting but that may be because I do not allow it to go to sleep on it's own. I have heard the restart issue is related to sleep mode. There is a way to turn that off, which I have done. Maybe you can try this setting on the Energy Saver control panel to see if it fixes it for you.
See the attached screenshot. It shows just the very first box being 'ticked' - to prevent the Mac from sleeping when the display goes off.View attachment 904909
Hope this helps and again, this is not a "cure" -- it just lets us use our Macs until Apple comes-out with an update to the Apple Security UpDate 2020-002 which is causing these issues.
Best regards,
