No texts, calls and data and service in and out.

Okay decided to flash candy last for a little bit just to get a feel of it. Flashed back to my stock backup and can't send texts or get them. Calls don't go through and calling the phone rings four times and to voicemail. Tried going through activation but even when it holds lte it claims no service. I do remember seeing an activation prompt when I flashed Candy maybe that messed something up? I'm lost here... Just tried ##72786# and phones reboots and comes back but it doesn't continue the process.
