Firmware not found after upgrading to 3.1

Upgraded from 3.0. to 3.1 and openhab didn’t work anymore. Rebooted and don’t even have access to the raspberry anymore. If I connect a monitor it says firmware not found.

Any idea what to do? Thanks

This is absolutely out of openHAB’s scope.
For a missing firmware error, you’d better search in a raspberry forum.

Maybe you are right, but it happend in combination with the update. Unfortuntely I don’t have a backup (yes I know…) but I have the ssd now mounted as a stick and want to backup/restore everything thats needed to the new ssd/installation.

Still out of openhab scope?

Perhaps if you tell us what difficulty you are having with that part?
