The initial oe_settings.xml file was corrupted and unable to be read. I moved it and the rpi started with a proper installation but I needed to set everything again.
A power failure made the rpi to shutdown not properly. Then when I started again, Kodi showed the defaults settings and the libreelec configuration said "Settings addon is not yet ready, please try again later". I used Kodi Leia
Is there a way to restore my settings without redoing everything manually?
