Upgrade via “system settings” from 4.2 went ok (Xperia X) but after reboot the phone keep rebooting AFTER reaching the GUI.
I had the time to enter the PIN, the SIMcard PIN - but before I manage to launch anything there’s a short freeze then reboot.
Then:
Reflashed to 4.2 , restore from backup, upgrade in terminal (version – dup) => same result
Reflashed to 4.2 , restore from backup, upgrade in GUI => same result
Is there any way to enable persistent and verbose logging to see what is causing the reboot ( I’d configure that while still in 4.2 then upgrade and retrieve the logs in Recovery mode)
