Default Upgrade from KitKat 4.4.2 to any rom 4.4

Good evening
before all I apologize for my poor English.
I'm trying to upgrade my Note 2 GT-N7100 GSM to a rom 4.4.3 or 4.4.4 trough last CWM recovery and previous too. I've tried several in vain.
At the moment I use KOT49H. N7100XXUFND3 but upgrade everything is ok but I lose mobile network connection.
Any advise?
Thank in advance
