[SOLVED] direct upgrade Gingerbread > JellyBean: two strange problems
I've upgraded from Gingerbread directly to JB stock via Odin.
The phone works fine, but I've got two strange problems:
- the lock screen is never showed, even if enabled in options; moreover, it doesn't ask for the sim pincode, so I'm not registered to the network until I go to settings > security > configure pin; I change the pin and then I'm registered until next reboot
- if I hold power button for 2 seconds, the phone doesn't show the pop-up window (with airplane mode, reboot options and so on...) but shuts down directly, without asking for confirmation!
I used JB before (same rom version) and it worked perfectly, until I had to downgrade (because I had to recover my imei number); Gingerbread worked perfectly too.
