EDIT: Solved
This is my first post here, so please bear with me
I unlocked, rooted, and flashed my VZW Gnex using Wug's Nexus Root Toolkit v1.5.2. The ROM I first flashed was AndroidME_GNexus_1.6.0.zip, but I also tried black_jb_v3.0.1.zip. Both have the same problem: after intial setup, the phone is not able to find any networks. I went to settings>wireless and networks>more>mobile networks>network operators>search networks, and it gives me the error "Error while searching for networks". When I try "choose automatically" it tells me "Can't connect to this network right now. Try again later." Wifi, NFC, and bluetooth work normally btw.
It seems to be only on JB ROMs, as I tried flashing CynogenMod 9 (20120801), as well as Google's factory image for 4.0.4 from https://developers.google.com/android/nexus/images . Both of these were able to find connect to networks just fine, so I'm assuming that the SIM is not at fault.
I tried rebooting, reflashing the problematic ROMs, and taking out the SIM and putting it back in, but nothing seemed to work.
Any ideas, as I'd really like to try JB and get into the rooting community (used to be an iOS jailbreaker, until I got sucked into Android
)
