Pi won't boot after full-upgrade.

[Richy_T]

I have a Pi Zero W running Stretch that has been working fine but I was having trouble using the camera library in pygame and it was getting a little long in the tooth so I ran apt-get update and then apt full-upgrade. Well, now it won't boot. At least not to a usable state. I get two lines of text about brmcc then the raspberry screen about shift for recovery mode and then no signal. A very unfortunate result. Is there something obvious I should look for? The original install was from Noobs, I believe.

I'll probably just get the important files off (I'm assuming the partitions are still good) and reinstall from scratch but I need to go to bed so I'll check in the morning.

Are you overclocking?

No. Stock settings other than enabling the camera, ssh and vnc.

There wasn't too much on there and I was able to grab /home so I'm just going to blow a new image on there. I'd keep it around for a bit longer for analysis but I don't have a spare SD card right now.

I *did* purge wolfram alpha because it was having troubles downloading and I don't need it (and seriously, half a gig with that thing?) and there were some errors about cleanup which didn't look too critical but who knows? There's a reason I'm a Slackware guy on important stuff
