Good afternoon,
I recently updated to 4.3. It was the OTA update for sprint. Ever since I updated, I can still connect to LTE, but as soon as I'm on LTE, I am not able to use any data at all. The signal icon is blue like it is connected all the way and in use, but I can't do anything data related until I fall back to 3G. I reflashed 4.3 from the sprint dev forum on here. Its the stock 4.3. I wiped everything before I flashed it. Any ideas?
Thanks in advance.
Yeah.... So I updated my ROM to the newest carbonROM nightly.... Suddenly I couldn't pick up lte, only 3g. So... I reverted to a previous backup. Didn't fix it. So... I flashed to a touchwiz based ROM, updated prl and profile. It said I had 4g but I'm pretty sure touchwiz just lies and says it has 4g. So I flashed back to the version of carbonrom I had been using previously without issue, still only 3g. Flashed mk3 modem, booted back up, no connection at all. Flashed back to md4. Still no connection. So I restored to a backup of vanir ROM. No dice. Still no connection at all. Flashed back to touchwiz, no connection. So I updated profile and prl. Nothing. Flashed mk3, nothing. Used the code to factory reset and reprovision the phone. Got data back. Again, touchwiz lies about 4g. So I restored my phone to an old carbonrom that I had had no issues with, and I'm only getting 3g. Seriously, what happened and how do I fix it?

Of course, after I take the time to write this, I get a text saying my provisioning was successful and it starts working
I decided to give Kit Kat another try a few days ago, but since then I have not been able to connect to LTE.
Prior to flashing I was running CM10.2 and my LTE was working fine. I initially lost LTE when I flashed PACMAN. I have also tried AOSB/ProBAM and Beanstalk. None of the Kit Kat roms gave me LTE so I gave up and restored CM10.2, but afterward I was still not getting any LTE connection.
I tried flashing the MD4 modem, but that didn't seem to fix anything. I've also heard that going back to stock could help, but I'd rather not have Knox if I don't have to use it. Which stock ROM here on XDA would be the best (Not planning on using the ROM. I just want LTE and then will flash back to Kit Kat)? Would a different modem fix my LTE issues? Is MK3 better than MD4, or are there any newer modems I should try?
Thanks for the help!

Any of the ROMS that have [TW] in the title should work. Full Knox only comes with flashing a tar file in ODIN, because your flashing every partition of the phone. Modified stock ROM zips do not have knox, unless otherwise noted. Make sure to do a prl and profile update when you flash to stock.

Flashed Wicked Sensations last night with the MK3 modem and I seemed to be getting LTE as soon as that booted. Updated my PRL and Profile, and then wiped. Installed AOSB again, and I seemed to be getting LTE until I rebooted. After the first reboot I seem to be stuck in 3G again.
Im currently running AOSB on 2 devices. When I first flashed them, I had the same issue until I rebooted the phone. After that I never had this issue again.

I think that's the opposite of what happened to me. My status bar said I had LTE when I first booted AOSB (this was after flashing/wiping TW). After the first reboot it connected to 3G and I haven't seen the LTE signal since.
I have updated the APNs, but I was using the same APNs for a while and had LTE on CM10.2 with them.

This is something wierd with Kitkat. I do not believe a fix has been found just yet. but if you dial *#*#info#*#* on most phones you can get into the phone systems and turn LTE back on.

I didn't know about this menu. Thanks for that. I went into Phone Info and tried selecting LTE only but it didn't connect to anything. Not sure what that means. There are other
There are some other options in there for networks (e.g. TD-SCDMA, CDMA auto). Would any of them help picking up Sprint LTE?
Other options include:
Turn off radio, CellInfoListRate
Turn on IMS registration required
Turn on SMS over IMS
Turn on lte ram dump
SMSC:_____________ Update Refresh

KitKat roms are currently having data issues. You could try backing up your current KK rom and go back to Stock, update prl and backup your DNS settings then go back to your backed up KK rom and restore from the dns settings you backed up.
How does one downgrade from kitkat to jellybean? I tried to just flash a jellybean ROM with a clean install and got an error?

It says something to do with missing a partition?

ohhh i had this issue but i figured it out for pacman and most roms just download nova launcher and when you do create a shortcut on nova ad click on setting an it should say apn once there u open it and youll see where it says ehprd something like that click on it and go all the way to the bottom and change where it says bearer to ehrpd and lte should work ^_^
Ok so I finally got it working, although I'm not sure what was wrong with everything in the first place. My buddy said Cyanogenmod screwed up a recent ROM, so maybe that code was in one of the ROMs I was using.
Each time I flashed back to TouchWiz (I ended up using Wicked Sensations) I could get 4G/LTE. I ran a **72786*, did a PRL & profile update. Prior to finding a working ROM, when I went back to BeanStalk/PACMAN I would lose LTE. After I found the updated BeanStalk ROM I flashed and it still had LTE! Happy days!
At this point I was able to send MMS somehow, but phone was having problems being recognized by the network. I could connect to LTE but couldn't use the data. After I updated the APNs everything started working again.

This should work http://forum.xda-developers.com/showthread.php?t=1794956

flashed that
Wifi works. Data/Calls do not.
What do I need to update?
Tried another 4.4.4 rom, same result
You probably have to update your bootloader, I had the same problem a while back. I Oden the entire 4.4.4 tmobile firmware and haven't had a problem since.

You need to read through the thread and see how other folks fixed the problem. The rom thread that you flashed.

i have the same issue with mahdi 4.4.4 and cm12 latest nighty! i had mahdi for 3-4 days no issue, then last two days no signal! same on cm12

Well If you really need your phone to work properly, receive and make calls, working mms and have long battery life and not blow up, you may have to settle for stock /touchwiz.

Apparently I have the old baseband radio, NJ2, and I'm getting no 3G/4G connection when I'm not connected to wifi. I can still get phone calls and text messages, but that's it. It seems like I need to upgrade to the MF1. Is there a way to update that by itself? I can't seem to find a tutorial on it, or the files itself. Any help would be appreciated.
As a side note, 3G seems to work just fine when I run a Slimkat rom, but not on any of the Lollipop roms.
I would like to know this as well
If someone makes a flashable zip of the modem then yes. Or you can try to make one yourself. But most (myself included) are on nj2 with data working fine. I was using aicp lollipop for months, then PAC lollipop. All good. Now running aicp unofficial marshmallow, still strong 4g lte data.
