z3+ dual Network Problem

[maherabdo]

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)
What Should I Do To Make Network Back Working ?

Try going back to the store location where you bought the phone and see if they can help check it.

Pleas repair your phone using pc companion or factory reset your phone. Go to setting-backup and restore - reset factory settings.

Plus also check network mode of it's fine. Go to settings the mobile network , network mode make sure wcdma/gsm is selected
