I made the mistake of updating as well. I am currently trying to recover from a backup USB image but it isn't wanting to do that either now.
I get it to boot up and start the process of loading, only have to have come to this point in the screen shot, then the display goes dead and the server IP is silent.
I am at a super loss now. I was a BIG supporter of this project, with multiple instances, and now I am starting to second guess if this was the right way to go with my home servers. Seriously thinking about converting to TruNas Scale at this point. All I have had are problems with this, either bad / corrupt / dead USB or boot errors.
The fact I have to wait 3 days to get a license moved from one USB to another is total BS.
