Samsung Galaxy S4 NO CONNECTION TO MOBILE NETWORK!!!! - Galaxy S 4 Q&A, Help & Troubleshooting

So my issue is that after installing Cyanogenmod onto my Samsung Galaxy S4 it does NOT connect to my mobile carrier network.
I tried using Tweakker but it doesn't list my carrier (US Cellular) So I can't get helped there!
I really hope I didn't **** my phone and some god-like hero can come to my rescue.
If you've had this problem and know how to fix it I REALLY hope you post here!

What version of CyanogenMod you installed?

The latest that you can get.

Do you have signal? IF yes, perhaps factory resetting your phone can do the trick?

I mean if you installed a STABLE version or one NIGHTLY. NIGHTLY versions are full of bugs. Try to install one stable version.
*EDIT: What model are u using: GT-i9500 or i9505?

I'm using the White Galaxy S4.

imei
dial *#06# and check if the imei number is the same as the one under your battery. If it's not, you could have lost your imei.

[Q] jlftte or jlftexx?

How do I know if my phone is jlfte or jlftexx?
I have a:
Galaxy S4 i9505 16gb
Baseband: I9505XXUFNC4
Android: AOSB 4.4.2 (I have flashed the jlfte version but have problem with the camera)
up!
Jflte is the modelnumber for the galaxy s4. Jfltexx is the International model of the galaxy s4.
Different carriers have different modelnumbers because of their lte frequencies. All of them have the Snapdragon 600. If you no carrier restricted phone then you have the jfltexx
Alternativly you could dial *1234#

And a jflte ROM is for every snapdragon S4. So for the jflteatt, jfltevww, jfltetmo and of course jfltexx. It's called a unified build. The jfltexx is just the i9505. So the device you own. You can flash jfltexx ROMs and jflte ROMs. They both should work.
Me Gusta!
@Me Gusta and @benni2903 thanks guys!

Are you sure? I've never heard of a jfltevj.. could you tell a little more about the device? Which ROMs have you been flashing and did they work?

I never changed the ROM, I'm using the original. This is the first time i'm trying to change de ROM.
I installed Root from JflteXX and it worked. But i know that i can brick my mobile if i install the wrong version of TWRP.

Yeah, im 99.9% sure you've got a jfltexx. The VJ is just your modem. Just go ahead and flash jfltexx twrp.
Also, the i9505 is nearly, I repeat, nearly unbrickable. Almost everything can be fixed by using Odin.

I'm in the same boat mate. Got my Note 3 a few weeks ago and was surprised to find a different mdoel N9007. Don't care about the knox status and really want to get rid of all the carrier bloatware. I can see the HK version of stock Samsung rom but not sure if it is suitable for our devices.

if it's the same model then it should work. You should check against your PDA version when you type *#1234#, if it is N9007ZH download the HK version, if it is N9007DI download the Australian version.

well, that is my problem. the only available firmware for my model is the carrier's firmware. there are no stock firmwares for Australia for my model.

Firmware is available on Sammobile but yes they are all carrier bloated.
For those of you still wondering, as long as you are on the 4.4.2 bootloader/modem, you can flash any aosp Rom and have no issues with mobile data or lte. The model number on your phone will change in the "about phone" section, bu if you can live with that, then no issues at all. I've just tried the Lollipop alpha build, and that worked fine, along with a bunch of other 4.4.4 AOSP roms and all ran smoothly.

[Q] Mobile network unstable i9500

when I bought the i9500 came with Android 4.3, when I connected to the mobile network signal was stable, but the upgrade to Android 4.4.2 the mobile network its totally unstable, making it impossible to download anything. But I put a modded rom with Android 4.2.2 the mobile network was stable. Currently I'm with MIUI. Any idea what might happen?

Do you mean stock rom? I don't know about Q variant but i think it has kitkat 4.4.2. Go to sammobile and there you can find firmwares for your mobile.
Or you want to check another custom rom?

Do you have an EFS backup? You can try to restore it and see if anything changed.

Hi, I had the same problem but I got a good news for you, go to this website (Chinese version) www.miui.com/getrom-110.html?m=yes&mobile=2 you'll find two builds one of them is the one that you've downloaded with no imei and the second one "Rain_bow build" is the one that I recommend you to flash .. And good luck ✌✌
