I have been using the Rapberry Pi with umbrel OS 1.4.2 for years without many issues, but after a 230V shut off in the house the device will not start or restart. So I have Balena flashed a new OS on the SD-card but I can’t go any further from here. I tried to remove the “settings.json” file but this has not solved the problem. So after a cold boot the Bitcoin application does not start. When manually starting the Bitcoin app the message “Restarting” takes for ever and nothin really happens. I can check that when I go to “Open Live Unit” and I clearly see that all applications show 0.00%. I am carefull using the “Factory reset” because I am not sure if I will keep my channels with sats on them…

Any Ideas to solve this..?
