Thanks for these replies! Tried it and most things went fine. I though had several “WTF” moments:
Flashing went fine. When I unplugged the cable the blue LED stayed on and pressing the power button seemed to have no effect. In the end I connected it again to USB and rebooted using
fastboot reboot. That worked well.
When I aborted the tutorial (long time SailfishOS user; since the Jolla 1), it suddenly no more accepted any gestures and the LED went red. It vibrated when it recognised my finger, but that’s all it did in that state. I managed to turn it and reboot of by pressing the power key for quite a while.
It then asked the PIN twice and the first time the vibration upon typing did not work (but also didn’t look like the normal SailfishOS login). It though seems to do that now with every boot. My XA2 did not do that, even not with the same version (22.214.171.124) of SailfishOS. (Although I’m not sure how often I rebooted with that version.)
When restoring the backup from my XA2 from a microSD card it at the end stated (in German): “Error: Couldn’t load notes” with a √ behind. And indeed, the Notes application is empty. But not only the notes are missing, also all contacts and calendar entries, i.e. the most important stuff.
This first looked like Manual backup to SD: failure to load playlists or notes but that seems about the actual backup failing, while for me the restore is failing.
Not sure if issues or if that’s “just as it is”:
- The “Network mode” switch only offers 4G, not 5G. I’m not sure if there should be 5G support or not. Android definitely did work with 5G.
Probably “just as it is” and unrelated to any Android version:
- The backup also didn’t seem to restore any UI settings or similar. (Never tried a restore before though.), but IIRC that never worked. Maybe also related to not having finished restoring the backup.
Anyway, otherwise seems to work fine. Didn’t have a phone call yet (just a missed call ), though.
