There is a simple way (or not, depending on your previous experience with flashing images) to get back band 4 LTE functionality after accepting the 4.2.2 OTA update on the Nexus 4.
After the phone has finished updating, put the Nexus 4 in fastboot mode and flash the radio image from 4.2.1. This gives you the option back to enable LTE and I haven't encountered any problems yet.
Thanks to the guys at XDA ([REF] Nexus 4 Stock OTA URLs - xda-developers) the Nexus4 4.2.1 images are at Nexus 4 Firmware – occam | Random Phantasmagoria.
Once the N4 is in fastboot mode, only a couple of commands need to be run from terminal:
$ fastboot flash radio radio-----.img
$ fastboot reboot
