I have two rPi set up for the children and they are having some issues.
They started getting sad face reboots after we suffered a few power cuts over summer. Stupidly I neglected looking at them properly and simply rebooted them over and over until they came back and then said I would look at them properly another time.
Well, now one of them wont boot at all, just a page of text of the OSMC splash screen followed by a sad face over and over. I have tried about 30 or 40 times and no luck. The other one I can get to boot every now and then.
My plan was to get the one that does sometimes boot up and running, update it (this has been neglected too), do a backup of all of their customised interface, and transfer it to the one that doesn’t boot at all.
However, I cannot even update the one that sometimes boot. All I get is a message saying addon failed.
I didn’t know what logs would be needed, so I did the lot.
Plug the old SD card into a SD Card reader and connect it to OSMC.
You could then use the File Manager to transfer but it would be more save to login via command line (SSH) and just do the adaptations manually.
Well depends what you what to take over.
Check <path to old sd>/home/osmc/.kodi/userdata/sources.xml <path to old sd>/home/osmc/.kodi/userdata/guisettings.xml
and potentially <path to old sd>/home/osmc/.kodi/userdata/advancedsettings.xml
If you are sure that all old files are still ok you can also copy the whole <path to old sd>/home/osmc/.kodi folder from the old SD Card
