Now had time to update.
Started update about hour ago and now if I open screen theres nothing?
Is it updated but cant doesnt show homescreen? Or is it just updating but update bar is broken?

Edit: Send myself message and screen turned on for few seconds but no sound or led flashing.
Edit2: I changed ambiance without screen showing anything (just saw lock icon change color as that's only thing I can see) I think it safe to try reboot?
Edit3: I ssh:d to my jolla and restarted homescreen and it started working fine.
