Google Nexus 4 - 4.4, LTE, and encryption

I see! Luckily, I did backup before rooting and flashing. Thank you for the info. I've flashed the LTE package. 4G connection shows at top right, but for one reason or another, webpages won't load while tethering or wi-fi hot spotting. System Preferences>Networks shows a connection, but no dice. Also, device loses 4G if I turn it off then back on. Maybe I'm missing something.
 
On a second note, just check the sticky threads from this section, it's pretty straight forward: Nexus 4 Rooting, ROMs, & Hacks - Android Forums at AndroidCentral.com
Follow instructions from : "Nexus 4 - Factory Image Restore" first, then follow: "Nexus 4 - Unlock & Root"
After that, just boot into TWRP recovery and flash these zip packages: [REF] Mako hybrid modem collection V2 - xda-developers
After flashing, factory reset your phone, otherwise the 4g mode won't be set as deafult and won't stick reverting to 3g mode on every reboot.

This is what did it for me. I already knew how to flash the hybrid radio and unlock/root, but the links you provided to edit the build.prop file is what helped. For some reason, when I did this manually, the phone just bricked and got stuck on the boot screen and I had to do this http://forums.androidcentral.com/ne...3923-guide-nexus-4-factory-image-restore.html. Anyway, 4G shows up in my preferred network type, finally! I just edited the APN's that were in there afterwards to match the setting for the Bright Spot network (which is T-Mobile). Can't wait to get into an area to test it (I'm a few miles north of the LTE coverage here). AFTER the factory reset is when you see the 4G show up in your settings, but DON"T CHANGE IT or you'll have to do this all over again. Thanks again for the resources and information, everyone who has worked on this. Also, after the reset, I still have root somehow. Probably because TWRP prevents you from losing it during a factory reset is my guess. Screenshot_2014-03-16-22-35-02.png
