LTE is not working on the CM11 M9 on my GS3. I tried flashing back to TW and updating PRL + Profile and flashing back to CM11 M9. No cigar. I tried flashing NDC modem and reflashing ND8 modem. No success either time. What do I do from here to get LTE working on my device because I like CM11 M9 but the lack of LTE kills my battery and hampers my phone's functionality. Any solutions are welcomed.
Are you a Sprint customer, or Virgin Mobile by any chance?
Have you tried going into:
Settings --> Mobile Networks --> and make sure your preferred network type is LTE?
What was your baseband version before your flashed CM11? When you ODIN'ed back to ND8 was LTE working? I would try getting the device back to stock where LTE is working and try flashing CM11 with GAPPs in PhilZ recovery. Just try the ROM and GAPPs without any additional add-ons (custom kernels, mods, etc.), boot up and see what happens.
I didn't necessarily mean unroot it. When you are on ND8, does LTE work?
I presume that you're flashing CM11 M9 for stability's sake, but have you considered flashing one of the more recent nightlies to compare results?
I had an issue kinda similar to that on a different sprint s3 I was working on. I flashed only the cm11 m9 with cwm and the phone lost data all together. I ended up flashing philz, then a new kernel and a cm nightly like previously mentioned and the problem fixed itself. I still have all the files if you need em, just pm me if you do.
Nightly Testing
I most certainly have tried different nightlies. It has made no difference.

Not to be redundant, but if you aren't already, please make sure you're on the latest version of PhilZ recovery, which can be downloaded here:
https://goo.im/devs/philz_touch/CWM_Advanced_Edition/d2lte/
You can download the .md5 file which is flashable in ODIN, or the .zip file which is flashable in a current custom recovery, if you already have one.
It is always best to make sure your recovery is up to date, especially when flashing the most recent build of a ROM.
Once you're in PhilZ, simply choose the option under "Wipe Data/Factory Reset" that reads "Clean to Install a New ROM". This will conveniently wipe the necessary partitions for you in order to install a ROM of your choice.
Try flashing only:
- ROM (CM11 can be downloaded here: https://download.cyanogenmod.org/?device=d2lte)
- GAPPs (I prefer the stock PA GAPPs package, downloadable here: https://www.androidfilehost.com/?w=files&flid=15800)
PhilZ also has a setting under "PhilZ Settings" to "Re-root System with SuperSU". After doing that, you would go to the play store, download SuperSU, update the binary, and reboot.
I would also certainly consider at some point getting the stock TouchWiz ROM environment setup as you typically would, boot into a custom recovery, and make a backup of the stock TouchWiz ROM as you typically prefer running it, so that you do not have to keep reflashing it via ODIN.
I bring this point up, because if following the procedure I mentioned in the previous post still does not correct the LTE issue for you, you could consider navigating to the /system/etc directory and copying the apns-conf.xml file from your TouchWiz ROM to the same file path in CM11.
