Alright so I flashed back to sense, and I still get no 3g/lte connection. If I tick on/airplane mode, I can maybe get it for a couple of minutes. Anybody else have this problem? Looks like I might have to send this phone back.
EDIT: Ok, so after flashing back to stock rom, I updated the prl/profile, and everything was fine. I was able to connect to 3g/lte with no problems. Does this mean I will have to stay on a sense based rom? Is there a way I can update prl/profile on custom rom?
