I have two Jolla Phones, one with a broken screen. To migrate all data from the broken device to the other I booted them into recovery mode and performed a filesystem level copy (rsync) of the root filesystem
/dev/mmcblk0p28 and the
After adapting the filesystem UUID in
/etc/fstab (since I did not reformat or do a blocklevel copy) the new device boots fine with the old data, but when I try to enable WLAN I only get the error message "Networking is not available. Please restart device". Bluetooth works, I have not tried GSM yet.
Where else are hardware specific files which I should keep? Are there other btrfs subvolumes or partitions with that data? Would a blocklevel copy of certain partitions help or would I risk bricking the phone?
