I'm running SHIFTAO5P 1.2 with radio 1.39.00.0627r. It's been fine for the last couple of days. Today my 3g/4g stopped showing up and getting no network. It's very sporadic, data will be on when I unlock it but when I try to access data it just shows the bars no 3g/4g. I checked the settings and can watch the Mobile network state go from connected to disconnected. Does this sound like a radio issue, if so which one should I flash. I had the same issue on my 1st TB and on this one when I 1st got it. My only concern is it may be a local network problem and don't want to flash a new radio if not needed.
