Root CM12.1 Unofficial Beta

You have to flash the APN fix for yourcarrier attached to the first post
Which rom should I use, the 9-20 is the latest one I see but that can't be it. What else do I need other that gapps, son fix and the rom? There are a lot of things attached in the op
 
Get vivavideo for it. It is more stable with recording. We finally figured out that issue in kitkat roms back in January
Do you know if Snapchat works? I tried this rom a while back and the son fix didn't fix the LTE problem, any suggestions?
 
I flashed the son fix and it didn't work. I did a clean install (wiped everything but extSD) booted rom. Then flashed the son fix and it didn't work. In fact, I didn't give me any data connection, and it kept saying that I had no sim card half the time, and the other half it was few bars with an ! Next to it.
 
Maybe within a week or two. Trying to get CM13 going...
I made a bootable build from the sources you gave me but NFC keeps force closing at boot, so much that the ROM is unstable. Deleting the NFC app from the system solves it but renders the camera as disabled.

EDIT: I stand corrected, the camera is disabled with NFC present in the system as well.

EDIT #2: I've atttached a logcat of the NFC erroring out multiple times if anyone would care to look at it and chime in. Basically, this:

Here's what i found wrong with the updated CM12.1 firmware. Really smooth and i wanted to keep running it but data doesn't work. I run Blisspop v4.0.1(2015/9/19). Data works perfect on only this one for some reason. i go to dailer code and change to "CDMA auto PRL" then change preferred network to 3G then flash Sprint APN fix then everything works but this method doesn't work on CM12.1 for some reason. It is a little strange.
 
What I do to keep LTE working i have sprint I use APN backup and restore and I just restore each time I flash a new ROM I believe I backed up the original APN from stock ROM I never have problems with LTE or any kind of service issues

They're stable, but far from fully functional. With no way to fix it without an official lollipop update.
The Motorola droid 4 xt894 has stock update up untill JB and is now able to run CM13 nightly official updates (without an official Motorola update to newer Android)

So what? There they have way more people working on it. As far as I understand the only difference between official and unofficial builds is that official builds have someone who has agreed to maintain it.
