Lucky that ur phone itself is refusing to update.
My phone stopped working once it upgraded to Build 10.3.1.A.2.67. There was no network once i updated.
Had to give it to the service center. And am yet to get a replacement. 15 Days now without a phone. Their service is sad.
Who would have imagined that their update would kill my phone.
Its Sony
Make.Believe 
Ha ha... ur rite. its Sony... They jus always make us believe. And we blindly believe like fools.
