Signal Problem after update

hoomanino — Mon, 06 Oct 2014 20:25:16 GMT

Hi,
After update My Xperia Z2 to 4.4, my device lost it signal (can't make phone call or mobile data connection), I did updated my phone to last available software ( 17.1.2.A.0.314) and my problem still exist.

Anybody got the same problem or clue ?

I just update from sony update center (90mb) then after restart network lost!
and I flash with flashtool and official roms to some another version but signal problem doesn't fix
I'm from Iran, and here we haven't LTE support. I think my problem is change in baseband version and if baseband change into before update problem will fix
