I upgraded from a stock rooted 4.4.2 to the OTA 5.0 using the ROM that was rooted. Some apps for my smart watch don't work in 5.0 yet, so I went TWRP and restored my backup. After booting, the phone will not get any service at all. It shows it's searching for service then gives a red "x" then starts searching again. This is process that just keeps going. I flashed the stock .tot file using the LG flash tool to get the phone completely back to stock. After doing so, the radio still won't get service. I then applied the OTA push of 5.0. After 5.0 was installed, the radio gets service without any issues. I used the LG flash tool again to go back to 4.4.2 stock and same issue; no service. Updated again to 5.0, and I get service. Any ideas on what's happening here? Is it the firmware for the radio that's having issues?
