MR5200-100NAS won't connect to any cellular networks after firmware update.

Device was working fine until it updated to NTGX55_12.04.12.00. Now it won't connect to any mobile networks, have tried multiple sims from the 3 major US carriers, all of which worked prior to the firmware update. Shows mobile disconnected and "searching". Mobile network on admin page shows 000-00 and cannot select manual mode, will "search" briefly and do nothing else. This is a device/firmware problem and NOT a mobile network problem.

Model is a MR5200-100NAS.
