For 2 days I've been banging my head against the wall, trying to in Libreelec (v8.0.1a on an S805 box) what should be a simple task: transfer my Kodi config files to a new install (I simply want to put my LE install on a faster SD card!). Doing the obvious, saving a backup in LE settings and then restoring the backup on the new SD card is impossible for me. I add the backup to the new SD card's backup directory. But after I restore, my install is corrupted, and after I wait for LE to fix the corruption, the backup is gone and everything is reset to zero. After reformatting and reinstalling LE on the new card, I tried just overwriting the default "addons" and "userdata" directories, with the folders in my old directories. Same result: upon reboot, LE is corrupted and tries to fix itself, then deletes everything I added and returns to stock settings.
So how I am I doing the transfers? Well, of course I can't simply access the .kodi files straight off the SD card. as neither my Mac nor Windows computers will see those ext4 files. Since I can't get the Mac to properly read&write to the LE SD card no matter what software I try, I installed Paragon's "EFTS" software, which allows you to read & write ext2-3-4 partitions under Windows. Maybe its not writing those files correctly, but I don't know where the problem lies. I'm at a loss to figure out how to move my addons & configs from the old SD card to the new. Surely this is possible with LE??
