It began with the updating to 15.2 --> black screen. Then I tried with the Recovering (Command+R)- Result: I got Seqouia 15.3 for free:-). Next perpetum mobile is a sudden black screen after a couple of hours;-) Yesterday I tried with Command+Option+Shift+R without success(or did I something wrong?). It looks like a dead end, at least for me. Dear Community, please help:-)

I have been running 15.3.1 for a few days no issues so far. What ever you do get a clean backup.
"What ever you do get a clean backup". What to do to get a clean backup?
How do I "Connect an external drive and use that to back up to with time machine"?. I have a LaCie with 1 terabyte...enough?
That should be plenty. Just plug it in to any usb port and open time machine options and add it.
What do you mean by a "cold reboot"?
I have the same issue. Have you found a way to resolve this? My laptop is owned by the company I work for, and they will not allow me to revert back to an older OS.
