Recently rooted and currently running cm-12.1-20150913-Nightly-kltespr on a Samsung Galaxy S5 phone that is on Boost. Ever since flashing Cyanogenmod I DO NOT have any LTE signal. If I change "Preferred Network Type" to LTE (recommended) I do not get any data/internet signal at all. Everything works fine EXCEPT LTE and Multimedia messages. Plain MMS works fine but when there is multimedia attached the message "No APN settings on this device" stays on my screen and will not go away unless I delete the message with the multimedia in it and reboot the device. Also although I am on Boost, the rom shows me as Sprint on the top left of my screen.
I have been researching for the past few days and see this is a common problem, at first I thought I had the wrong baseband version and flashed G900PVPU1BOA6 thinking that would fix it because that was the baseband I had prior to flashing Cyanogenmod, after flashing Cyanogenmod I had baseband version G900PVPU30BG1. That was not the issue as everything seems to work the same as it did with the previous baseband version.
I did the remove sim car, restore to default APN settings and that didnt work.
I also downloaded Root Tweaker from the Play store and updated Cyanogenmod APN settings and that didnt work either.
I tried to flash back to stock so that I can update my PRL, get LTE and try the terminal emulator method BUT I am unable to flash back to a stock rom. I dont understand why. Maybe the downloads I am trying are no good, not sure. BUT I know there has got to be an easier way, so if anybody can help me out I would really appreciate it. I'm pretty sure its all with the APN settings. I also feel like I maybe took a step back by flashing my old baseband version. Any help from somebody that can point me in the right direction would be appreciated. Surely somebody has the S5 running on Cyanogenmod with LTE working.
