Otherwise I would flash other firmware or repair with PCC.
Okay so actually solved the issue.
I reinstalled/repaired the FW using Sony PC Companion and now LTE works perfectly. But the side effect? I heard that 4.4.2 causes many bugs and seems like I just got the phone sluggish one.
Phone feels sluggish in different parts as well as when I tap the recent icons button. Also the animation for WiFi turning on and off is not there anymore...
I don't know what's happening anymore....:/
