Cannot get my S4 to connect to 4G. I have MDK rooted/unlocked running Carbon Rom, tried Sonic Rom and GPE 4.4.3, used Odin back to stock unrooted and still no 4G LTE.
Whats happening: on stock I had 4G at first boot-up but then it cannot connect anymore. When on Carbon if I change APN back to LTE Verizon standard it connects to LTE for a moment but kicks back to diff APN and 3G only. Same on any AOSP or GPE rom.
Any ideas? hardware issue?

Well could be your Sim card possibly since you had that issue on stock MDK
I know some aosp Roms have been getting updates to their APNs and I've ran into this same issue myself.
Currently I'm on this one http://forum.xda-developers.com/showthread.php?t=2760650
And my data is perfect. The APNs are not accessible however. But still no issues for me.

Also have you tried flashing different modems? I know you used Odin so that'll put you back to MDK but before going and getting a new Sim you could try that ROM I linked you to and maybe flash the NC5 modem as well. That's what I'm running

I've tried a couple roms. It seems the issue is apn won't stock. I change it and sometimes get 4g for a moment then it resets and no 4g and if I delete all apn but one it still won't stick to that one.

And you used a full wipe MDK Odin file? You should be able to at least get it back on stock I'd think. And if not that point to your Sim most likely or who knows... Hardware issue maybe.
Sims are free at any corporate Verizon store and something like $15 at retail ones. May want to at least try that.

Have you tried the app Automatic system settings? You can select LTE only mode and force it into LTE. Ever since Kit Kat, I've had 4g far less than before. It constantly switches out to 3g when not in use for a while. Happens mostly inside buildings.

No they don't care. Just if you make you feel better throw MDK back on there and freeze SDM but I've been in there for Sims running Liquid Smooth. Nothing they can do. Especially just for a Sim. That's a separate issue.

Hello people new here and im digging around with no exact answer so I decided to open a thread. I just rooted note today and I flashes CM9.1 by cyanogen (QuincyATT) version and I may be having data issues or not lol.
When I try and choose lTE/GSM under settings it doesn't let me; just defaults back to GSM automatically. Also I feel like data goes in and out or maybe its just me. Any suggestions? I'm in an LTE area...

Yes. Will LTE work automatically? I'm assuming theres no icon for it.
Sent from my SAMSUNG-SGH-I717 using xda premium
It will automatically connect if available. The icon is 4g. If you see H then you're not on lte because it isn't available or possibly because of that setting.
This is mine by default. Honestly not sure if it makes a difference.

Damnit lol. I'm in an LTE area but mine just stays on h+. OK I'll try and figure out whats going on. By chance do you remember on the original rom what the LTE icon looked like?

On the stock ROM, the icon was always 4G unless you were in an lte area....Then it was 4Glte.

Not sure if this will do anything, but have you tried clearing cache and dalvik in recovery and then seeing if setting will stick? If that doesnt work, try wiping again, but then dirty flash the ROM and gapps. Another option(and I'm not sure what this will do) is trying to clear data in settings apk and starting over with all your settings. That will wipe everything back to stock settings as if you just flashed. Good luck guys.

Man I really don't want to switch to GB base lol, I'd rather be on touch wiz. After doing some research I'm starting to believe it may be the modem. My phone arrived with ice cream so I'm betting that has a lot to do with my issues. I'm going to change my modem for the first time to see if I can switch to LTE
Sent from my SAMSUNG-SGH-I717 using Tapatalk 2
Possibly a dumb question. But after you deleted your APN, and entered a new one, did you press menu and save?
Proper LTE APN for your carrier, with LTE sim card and LTE plan, you should get LTE running.
for CM9/AOSP/AOKP/CM10 type roms, LTE will show up as 4G.
Another way to test is to install a UCLF6 ROM. Get that up and running. Then go to the APN settings, and the LTE APN's should be loaded.
To confirm LTE is connected, make sure you are in an LTE area, and you can check in Status, or open up the phone dialer, and do *#2263*.
Then select LTE, and All types in LTE. If you are running in LTE there, you should be able to get it up and running with any CM ROM.
I switched to the touchwiz black star rom and I'm on LTE right now. Same modem I had on cm9.1. Its puzzling why it wouldn't turn on. Oh well ill stick with touch wiz thanks anyways guys!

You *might* have to go back to stock if the SIM can't be activated for Verizon. The debloating process might have removed something needed.
Would a factory reset delete beans plus root/relock bootloader ? Thanks ! I will try both of your suggestions and keep you posted !
I'm just curious have any if you powered the phone on without the sim. Then powered down, put the sim back and powered on?
It is such an easy thing?, but maybe someone overlooked it.

After all of that fighting the system, changing the sim, reloading stock the sim holder is sort of wide and the spring forces it just a bit off of the contacts I adjusted it just a bit rebooted and got 4g back. Always check the stupid things that it could be first. Lesson learned for the 10th time. Though I checked it multiple times before resorting to a system restore so who knows what caused it.

Try putting your Sim card in someone else's phone that has LTE. If they only get 3G, it's your card. Of they still get 4G, it's something else with your phone causing the problem.

Something similar is happening to me. I'm on Carbonrom 1.8. 4g just stopped working. Have been reading around trying to get fixes. Got a new SIM card from Verizon and it still didn't fix it.
In my phone status it says I'm on CDMA - eHRPD:14, I believe this indicates I truly am on 3g. If it were 13 it'd be 4g. I think I have that right. I haven't come across much that's helpful although it seems this isn't that rare of an issue. Trying to fix as much of it as I can on my own. I've yet to revert back to stock. Have tried going to Beanstown, that did more harm than good (broke sms and didn't go to 4g).

Beans ROM is basically stock if you went to that and still didn't have 4G then there is something wrong with your phone. Try the dialer fix (Dialing the number posted above) and if that doesn't work I would start thinking about a warranty replacement.

Most likely would have happened anyways. Rooting and ROMing don't touch the modems that control your cell signal.

This alone did not work...however, I got a new sim card after doing this and I'm back on 4g. Got fixed a bit ago but was unable to post. Thanks for the help. No 4g was bugging me, but unfortunately it means I'm stock for the time being
I was being a dumbass and dialed *228 thinking it will update my PRL and improve my signal. Immediately after programming, I was limited to 3g connection. I lost 4g/LTE connection. I fixed this by going to the Verizon store and asked them for a new SIM card, which was free of charge.
*228 is for 3g phones ONLY. Not for the GS4, unless you like 3g connection speeds...
It is a relatively simple solution, but it can also be easily avoided. Save yourself the trouble, and don't make the same mistake I did.

I was being a dumbass and dialed *228 thinking it will update my PRL and improve my signal. Immediately after programming, I was limited to 3g connection. I lost 4g/LTE connection. I fixed this by going to the Verizon store and asked them for a new SIM card, which was free of charge.
*228 is for 3g phones ONLY. Not for the GS4, unless you like 3g connection speeds...

When you have cable TV and nothing seems to be on you get bored. When you get bored you try to improve your cell phones data connection. When you try and improve your data connection you use *228 when you use *228 you limit you data speeds to 3g and it requires a new sim card. Avoid using *228, ditch your cable TV and sign up for for direct tv. Lol

I did that once. Apparently you wipe the SIM card when you do that and you have to get a whole new SIM card. I was having data issues as well and thought, I'll just reprogram the phone with *228. Yeah, no that didn't work.

Well unfortunately I found this thread after the fact. Can anyone confirm what joshm said? Will it come back in a bit or should I just give V a call?

I made the same mistake too. I waited a few days and no 4G/LTE came back. I tried going to the local corporate store and they wouldn't even talk to me as I was running a custom recovery & rom (on MDK bootloader!). I went to one of the retail stores and they helped me out with a new SIM card.

Thank you .. I had just got through watching the eye patch one before reading this thread so... good times.
So is there a way to do the equivalent of *228 for your LTE that updates the prl for your 3g?

4g prls are checked for updates when phone is cut off and cut back on after a 5 min period, what I was told from verizon a year ago

another way to get prl back is to clean flash a rom and the system automatically does a prl update on boot if other steps dont work

I did this a month or two ago and lost my 4g. What I did was contact Verizon Support (via web chat but you could call them). I told them I accidentally dialed *228 and lost 4g and asked them if they would manually push a PRL update to my phone. The technician had me power off my device and when I turned it back on all was well, had 4g again.
This saved me the awkwardness of taking my phone into a store where they would see it was rooted with a custom ROM.
Sadly, found this thread too late. I dialed *228 and had to go get a new sim. At least no questions were asked at VZW.
Yeah . . I did it too lol
If you want to change your connection or update your prl's there's a code you can typee in the phone dialer to bring up a hidden menu.
In the dialer type *#*#4636#*#* and then go to phone information and scroll down and change the option to CDMA/LTE and that always works for me.
I've heard of a few people that this hasn't worked with,but other wise it has always worked for me.
