Cyanogenmod 12.1 works with Ting on Samsung Galaxy S4
Answered

Here is the link to the working release: http://forum.xda-developers.com/showpost.php?p=59744479&postcount=1

I had been having the most difficult time upgrading to the official Cyanogenmod 12 and having it work with LTE service.  APN's were set up correctly but no LTE service just 3G. 

I had been using the methods I traditionally had done by going back to the original Sprint Samsung Touchwiz build (used a default recovery build) and making sure that LTE worked as well as updating the PRL and Network Profile. I also made sure the GPS was working. 

Then I would use ClockworkMod (CMW) to install the Cyanogenmod 12 nightly zip for the Sprint Samsung S4 (SPH L720). Unfortunately every time I did the install LTE would not work. I played around with the APN settings but no luck.  

I finally decided to do a clean wipe and install TWRP recovery and install the AntaresOne Cyanogenmod 12.1 optimized ROM.  It worked perfectly with the install. I don't know why the official nightly Cyanogenmod12 didn't work with LTE, I'm assuming it may be because I dirty flashed over the original Touchwiz build, or that the recent Cyanogenmod 12 nightly builds have a bug. 

In this build there is no APN settings in the network settings so you have to use Gesture search app or maybe the APN App to manually change the APN for Ting to add "default," under APN Type next to MMS then check the box for TIng to select that APN.  The initial install automatically says LTE, but don't believe it as when I tested the speed it was only 3G speeds and was probably on Sprint's 3G network and not LTE as it says in status bar.  

Good luck. 

Hope this helps.

  • Unfortunately anything after the 4/13 release doesn't have data service working.  Bummer. If you have the 4/13 release you are good to go.  But don't upgrade.

  • I've got Cyanogenmod running on these phones like a Swiss watch.  No issues with LTE at all and that includes CM 12.1.  I have a custom apns-conf.xml that I modified for Ting.  Download it at the link below.  Just flash it right after flashing CM 12.1 and Gapps.  I have it running on my S4 and another S3 without issues.

  • Just want to add that I have it currently running on the latest May 10th official release of CM 12.1 without issues.

  • Sorry but had to add another comment.  It's also tested with SMS and MMS.  Sending and receiving pictures work too.

  • Danny, are you using Antares/Alucard24's build?  Or the official CM 12.1. for SPH-720? or JFLTEXX?  Please let me know.  Antares/Allucard's build which I think is built off of JFLTEXX is very speedy and does a good job of battery saving was a preferred build for me. I used the official nightly SPH-720 but it was not working for a while and that was when I found Antares build.

  • Will this work with CM 12 on a Nexus 5?

  • I use the official build on my S4 from the link below.

    http://download.cyanogenmod.org/?type=nightly&device=jfltespr

    Never tried the Antares build since the official build has been working great for me.  I didn't realize that they went off the unified builds so I was late in moving to CM 12/12.1 until recently.

    I don't see why it wouldn't work with the Nexus 5 Robert.  My zip is for Cyanogenmod so it should work for all phones on that version of Android and maybe some others based on AOSP roms.  I tried it on LiquidSmooth once and it worked.  I just ordered a Galaxy Note 4 so I will be trying it on that phone soon.

  • It works on my new Galaxy Note 4 with both official CM 12 and CMRemiX (cm 12.1 with some tweaks).  I have 4G LTE and can send and receive MMS.

  • For what ever reason, I've lost 4G LTE again. It worked for a day or so then now it only gets 3G, using 0518 official build JFLTESPR.

  • I am using the CM12.1 Optimized build also, and LTE works fine for me after I added default to the APN type section.

  • I couldn't get the apn download link to work, but I found another one out there that seems to work. Much thanks to Danny Amborn for doing this. Worked like a charm and totally saved the day!

  • H F, did you ever get this resolved? I see two people who seemed to have gotten lte to work. I've tried everything mentioned in this thread and I get no lte on any cm 12.1 rom. I'm about ready to try Optimized CM12.1 one more time to see if I can get that to work.

  • Yes, this did get resolved. A couple of month later as apparently Cyanogenmod had wrong configuration for Ting's APN or how they implemented the APN configs for LTE. I don't remember. Anyway CM12.1 should work. I use the optimized build here: http://forum.xda-developers.com/galaxy-s4/i9505-orig-develop/exclusive-antaresone-alucard24-s-t3066696 . By the way, I would highly suggest doing a clean install starting from scratch as somethings don't work properly if you do a dirty install. Follow the directions they give and things should work properly.

  • I am running the optimized Cm 12.1 build with Danny's custom APN (flashed after Cm 12.1 and GApps). When it connects to LTE things work great, but there are times when the data connection drops out and I have to restart the phone to get it working again. Any suggestions on how to resolve this?

  • After the last update of Optimized I lost my LTE. Double checked APN settings and they look good, but no LTE. Switched to Bliss Rom and same problem, but no bluetooth problems that Optimized has so staying with it. I would try the new APN file but neither download link works.

  • If you are using this ROM which I currently am, you do not need to install any custom APN file. Just go to the Mobile Network settings click on the Access Point Names setting and where Ting is listed all you need to do is to edit the "APN Type" and add "default." in front of "supl,mms" and save. To prevent it from jumping to the Sprint default setting, remove default, from the Sprint LTE Internet and Sprint LTE OTA APN's from the APN type. This way it will always stay with Ting's APN. And save.
    If you lose LTE and can't get it back, reboot, sometime for what ever reason it loses LTE signal and doesn't get it back.

  • Crud, I thought maybe we were on to something, but removing "default," from the other APN entries still gets me only 3g. One other note of interest, Ting's support refused to tell me the proper APN settings. The technician had no knowledge and said she couldn't escalate it because it's a custom rom issue. How hard could it be to publish the proper APN settings from an authoritative source? They're not secret. It seems there is only one right answer and it would allow us to quit thrashing around trying to fix something that maybe can't be fixed?

    Thanks for the tip on Bliss Rom. I'm getting tired of bluetooth dying.

  • Well, I went back to stock rom using the info here: http://forum.xda-developers.com/galaxy-s4-sprint/development/rom-stock-od2-odin-flashable-t3133661
    Now I have LTE and I can look at the APN settings first hand. There are two differences I see right off between stock settings and the settings in CM 12.1 roms. MNC is 000 instead of 120 and Bearer is set to LTE. The name is also different but I don't think that matters.

    Here is what my phone now shows:

    Name: APN2 LTE internet
    APN: n.t8.ispsn
    MMSC: http://mms.plspictures.com
    Multimedia Message Proxy: 68.28.31.7
    Multimedia message port: 80
    MCC: 310
    MNC: 000
    APN type: default,mms
    Bearer: LTE

    Some of the other APN entries may also have some slight differences, but I don't think those would get used unless your phone is searching for a network. Someday I'll go through and type them all out.

  • I lost my internet like a month ago as well. I didn't update anything so not sure why it happened! I was running antaresone's cm12.1 from august. I tried the old cm, latest cm, optimized cm from JDCteam but nothing worked so far. I am thinking if I should try the marshmellow 6.0

  • I know that the last and final version of allucard's (JDC)Android 5.1/12.1 Cyanogemod optimized, worked fine. He did say that he would not be providing any updates to after the final release. I would do a complete clean install if your data doesn't work. When I mean complete in TWRP, format all of the partitions, except for your external SD card then install the lastest version. By the way, I wouldn't upgrade to JDC 6.0 as of yet as there were several issues not resolved like GPS not working. If that doesn't work, I would install the original Samsung build (Touchwiz) make sure that data works and GPS, then do a flash to the 12.1 Cyanogenmod release. By the way, I replaced my Samsung S4 phone fairly recently with the Nexus6P and run it on Ting's GSM (T-Mobile). I have to tell you that the data seems to be more stable and I have to reboot less often when data drops to 3G when it is supposed to be on LTE. Coverage is about the same as with Ting's CDMA (Sprint's) network.

    this is what finally worked for me. Sure the software is a bit bloated but all the things work if installed according to instructions :)
