I love my GNex. Its always worked fine. After the Verizon rollout of Jelly Bean, I can no longer make or receive calls or text. I'm not sure about data because I don't use a ton of it and I've been on wifi since the update. Everything has been stock. I have not fiddled with ROMs or rooting. VZ is not available right now so I thought someone here might know what's going on. The limited resources I see on the matter have to do with rooting and installing versions other than VZs rollout. Am I going to have to rollback and install it again? Any way to backup my data if that is what I need to do? Much appreciated beforehand. I have not tried taking out the battery or the sim card. I'll try that now. Thanks.
