Possibly a bit offtopic (but related):

Dumb Jolla (or me )!

I updated device to latest äkaälöülëiöäkä version. All fine. Had all patches disabled. Updated all available SW/patches.
Then a few days later I decided to activate the patches again. Did it all-in-one step. Went through all installed patches and tried to apply (some did not work but that was/is known).
Restarted lipstick and ...
BAM
An empty screen (with just the wallpaper) looked at me.
Nothing works, no apps, no up-down-side swiping, no notification screen. The display stays empty all the time. Only the lock when swiping from top works (shows the lock icon). Furthermore the coderus lockscreen on power button works with displaying selections (and selected app -torch- starts but wothout screen). That's it.

Unfortunately it seems that the upgrade changed the root password? As I cannot ssh into the device (do I have to use root or or user or what account?). Even it worked I had no idea what to check else disabling ausmt.

Any hints?
