i did a OTA yesterday and now i see a message at my homescreen. saying: Unauthorized device.
this app is not compatible with your phone.
and my homescreen is black i can't swipe etc. but i can just normally type in my pin. i can still slide down the notification bar. and go to my settings.
and pick up phone calls but i can't make calls since i can't go to my apps or my home screen. it says the message above.
my phone is rooted. i flashed back stock recovery using Flashify and did the OTA. and this happend....
thank you guys for replying !
