Hello Everyone .. I have a Sony Xperia Z3 Dual D6633 .. Originally Came With KitKat 4.4.4 OS .. Everything Was Perfectly Working..
But After I've Updated it to The Lollipop 5.0.2 .. Good But The Network Is No LONGER Working (The Z3 Can Read Sim Cards.. Request The PIN Code But Can't Receive a Coverage At All) .. I' From Living In Syria (Middle East)
