I have just unlocked mibe phone 1.1.2 and 04.02.13_G.
I got signal with mi carrier but when I try to place a call the phone changes the page ang returns to home.
Same happens with SMS.
WiFi is working OK.
I've just tried to upgrade using Itunes but I got an error "1602"and could not upgrade.
1- Should I restore the phone and do the same processes again?
