Root Still no LTE **RESOLVED**

Well, I have tried everything. At least I think so. At this point I am tempted to go spend another $59 to get a new Volt.

When I first bought this phone I rooted it and installed Candy. Noticed no LTE so I followed all the different advise on getting it back. The only way to get it back was revert back to stock and run the ##72786#. No problem.

At some point between flashing back and forth between stock and CM12 something stopped allowing me to get LTE enabled in stock. I tried everything I can think of, including everything listed here in the forums. Flash this, then this, then this, etc... I have even called support no less then 15 times. I even went to the extreme of closing my account, waiting 4 days and re-activating it. Also, got a new SIM from sprint. Still no LTE.

As a last resort, my son just happens to have the identical phone (with LTE working) and I rooted his and copied the TWRP over to my phone. Still nothing.

Any last ideas before I bounce this phone off the ground and maybe get another? I know I have seen a few members just say 3G is good enough. Not me, I had LTE Spark just about every place I go.
 
flash the cm12.1 rom. change apn settings port and proxy to 0. you shoupd get lte back with that if not try dialing that activation number. then just flash stock again or whatever rom you wanted
 
The way I fixed this when CM wiped my LTE was to flash Candy, gapps, and the APN fix all before first boot. When it booted, I had to switch to the other APN, even though it appears to be identical. Maybe it forced something to get rewritten.

After that I flashed back to stock and haven't messed with those, or any other ROM since.

Did you manually add one or just pick a random APN and restore back to stock?

The APN fix installed 2 APNs. The default didn't work, but switching to the other did even though it appeared to be identical, so it must've forced something to be written when I switched.
 
...and out of no where I was able to get LTE working on Candy ROM! I could not get LTE on the stock rom, so for one last try I flashed candy and got it working.

I think the deciding factor here was that most of the resources online that stated cinet.spcs as being the sprint APN were not correct for a prepaid account.

I have a second volt that I pulled the APN settings from using ##DATA#.

I used:
Apn: n.sprpre.ispsn
Type: default,mms

The other settings seem to be sprint defaults.
 
Are you working with a sprint volt? With the current version of CM 12.1 I've noticed that if you go to your Apn settings and select one of the other apns it will kick into LTE(if that is set as your preferred network atleast)

Also are you saying if its a sprint prepaid account? That alone could be causing the issue but if your on a stock rom simply using an activation app or updating the profile/prl may even fix that.

if you can add an additional APN with these settings
Name Sprint
APN cinet.spcs
Proxy blank
Username blank
Password blank
Server blank
MMSC http://mms.sprintpcs.com/servlets/mms
MMS Proxy 68.28.31.7 6
MMS Port 80
MMC 234
MNC 15
Authentication type not set
APN Type internet + mms
APN Protocol IPv4
APN enable/disable blank

Then reset phone if lte doesn't kick in but make sure your settings have LTE as the preferred network

Maybe this will help. Maybe not. Came off my stock HTC Desire 816

Good lord, I went in to view the APN, LtE vanished and won't return. Sprint I hate you.
 
A Fix that worked for me (Boost Mobile).
I am running CM11 4.4.4 so I have easy access to APN settings.
Create a new LTE APN with the settings shown in the attached pictures, save, delete the other APN's, reboot, and hopefully this works for you.

- edit
Just modify the LTE APN with the following
APN: n.ispsn
mmsc: http://mms.sprintpcs.com
APN type: default,mms,supl,hipri
That's all I really needed.

Try installing CM11 4.4.4 stable and modify the APN as my earlier post states.
 
So I don't know if anyone is still having problems with this but if you are, flash cm12.1.

After that, flash gapps and your carrier APN zip and reboot to the newly installed rom. Open apns, select the one that says ehrpd, and hopefully it will toggle over to LTE for you like mine did.

I didn't have LTE on my virgin mobile volt for almost 3 months now and doing the above brought it right back. Hopefully it will work for you guys too.
 
I was able to get my LTE back on a ZV5 rom by modifying the Boost APN fix zip wth different APN's.
Here is my sequence that was used:
If this doesnt work modify the APN's in the zip to find what works.
I got the settings from testing on a CM11 4.4.4 rom.
FYI - I have a Boost mobile Volt with the camera bug on CM roms

I'm confused sorry. What root explore should I use and where do I see those permissions. I have virgin mobile. I see my that my LTE had a network provider and an IP address. But I cannot connect to it.
