Yea of course. I've done just about everything (updated profile, Cdma/LTE mode, rebooted, flashed back to a stock rom, cm9, jelly bean, aokp). If anyone here has a Galaxy Nexus, what radio and PRL are you using?
Right now, my radio is FD02, PRL is 25003, and it says network type is CDMA eHRPD:14...not sure if any of that matters, though.
