about two month ago I installed Sailfish_OS-Jolla-18.104.22.168-h3113-0.0.7.52 on my new XA2 (h3113, single sim, german). It worked well until I tried to migrate my data from my JollaC to it, using backup/restore from settings (“Einstellungen” - “Datensicherung”).
During restoring the data on xa2 the Phone hung at about 60%. I was able to turn it off, but could not turn it on again - no led on, no other sign of live. Also plugging in USB did not show any sign of live. After two days the led suddenly lit red when plugging in and I could restart the xa2 and use it again. It worked fine for some weeks - until last week.
What happened? I connected it to the USB charger when ~30% capacity was left. After a while I saw the led flashing white, but no notification was on the screen and charging still in progress (but nothing which might hint an issue). Next morning it was dead again (which is now over a week ago) and I could not restart it since then. I tried everything: vol up+power/vol down+power/only power/only vol up when inserting usb to power. No sign of life: no led, no screen, no vibration, no usb communication with pc, nothing. To be honest, at the end I even opened the phone (desperate times - desperate measures) and disconnected/reconnected the battery. Did not change anything
Now two questions:
- is backing up/restoring data between different models (JollaC - XA2) dangerous?
- is there still a chance, to get the device working again (except the combination of volume and power on button triggering - these I have tried to exhaustion)?
