Unofficial LTE support for Google Nexus 4 gone after Android 4.2.2 update
Android 4.2.2 update breaks the unofficial LTE support for Google Nexus 4
But now that Android 4.2.2 is out, the Google Nexus 4 can't connect to LTE networks anymore. In particular, it's the new radio software version included in the patch that drops LTE connectivity support for good. Well, it was bound to happen sooner or later. After all, the Google Nexus 4 has not been approved by the FCC for use with LTE networks in the U.S.
Of course, that's surely not a big loss for the majority of U.S. Google Nexus 4 owners since few of them will be affected by it. Still, if for some reason you demand having unofficial LTE access on your Google Nexus 4, just don't hit that "Software Update" button.
