Be aware,
I flasshed every available Volt rom and never lost LTE till i did a advaced Wipe.
If your flashing various Volt roms do not not do a Advanced Wipe in TWRP or you will loose LTE, a simple factory reset is all you need.
You will have to reflash and start from ZV3 stock again to get LTE again.
It's my understanding that the radio is installed in a special partition so when we do a advanced wipe such as system,data, internal Storage and sdcard it wipes the radio, and reflashing it does not restore it.
