I am sad to report that my slice (with a CM3 and no internal HDD) has failed to upgrade.
I was running 9.2.1, and everything was smooth.
Then I decided to upgrade to 9.2.3 today. I did the upgrade via the GUI as usual.
The file DL as it should and my Slcie rebooted to apply the upgrade.
I should say that I did not really look at what happen since I never encountered any issue with upgrade before. I think that upon reboot, the Slice started to upgrade (reading the archive, etc) and I assumed that it did what it was supposed to do. Then I got a black screen.
Usually, the Slice reboot one more time after this and go into Kodi.
This time it did not happened. I waited 5-10 minutes, unsure what to do and then tried a hard reboot by unplugging the power.
The Slice switch on (I always have the first colourful square picture) but then nothing. LibreELEC and Kodi do not boot.
I have tried both the Kodi remote and ssh and nothing there.
Any advice on how to restore the situation?
