So I've been using my Galaxy for a bit, and after flashing a few ROMS my mobile data, is only able to pick up EDGE, which is a pretty big deal for me.
It started yesterday when I flashed CM10.1 and then AOKP. Those were both fine, I was still able to get 4g with them, then I came upon a ROM on here that suggested I format my system before installing. So I did that, and ever since then I have not been able to get more then EDGE. I have since returned to stock rom and other roms and they all yield the same result. I have noticed my IMEI was at 0, so I did end up injecting that, but still nothing. My signal strength right now is at -59 dBm. And unfortunately my Mobile Network Type reads: Edge:2. I can provide you guys with different details such as my APN and all if you need.
I also tried my SIM card on my other phone and was immediately able to get LTE on it.
Any help would be greatly appreciated.
So you've checked that recovering your IMEI was successful and is now displayed? You said you've also made sure your APN settings were correct, right? Do you have the "data enabled" checked and the 2G only unchecked (in mobile network settings)?
Correct, I injected my IMEI and it is the same as on the inside of my phone and it shows that in my settings. My APN settings are correct, I found the LTE settings here and tried them and still nothing. My data is enabled and 2G only is indeed unchecked.

Well I went to the link. I believe I was already on the latest modem, so I decided to flash the one above which would be the second newest. The only thing it changed was now instead of EDGE:2 as my mobile network it sasy GPRS:1
I;m not sure what to make of that.
I have somewhat made process on this issue. When I first turn on my phone my Mobile Network Type is UMTS:3 and I am able to get a 4g symbol but the signal is at -113. This is only when I enable mobile data real quick after putting on the phone, if I don't do that after a minute it will change to EDGE;2. The problem is there is no service with it turned on and my asu is at 0. But when I turn it off the signal immediately gets better and I get asu's.

Hey everyone!
So I picked up a tmobile s4 to use on ATT since I read it was the most unlocked due to bands / bootlocker. I unlocked it via the method described on this site via the debug menu.
Popped in ATT sim, everything looked fine initially.
1. I'm only getting 4G in an LTE area. device hasn't picked up any LTE anywhere yet.
2. When I go under "Network Mode" and select "LTE/GSM/WCDMA (auto connect) the signal dies out and it always reverts back to GSM/WCDMA"
3. I've called ATT a few times and triple checked that I'm on an Android LTE data plan, so that's not an issue. ATT techs suggested it could be a device issue and maybe I should take it into their tech center.
4. Tried to set up ATT Visual Voicemail, that failed also.
So can it be a Sim issue? Maybe something on tmobiles side? Since device was never active on their network. A lemon S4?
I've run out of options
Any help would be appreciated.
TIA!

Hi, guys I recently ran into an issue with the build prop modification in regards to network selection. If I enable the network selection as pointed out in one of the other threads and select LTE /CDMA my phone will lock on LTE however no phone calls can be made out or recieved. I had to reflash to 10k then reroot and then change the build prop to CA/TLS and finally hardreset via stock recovery. Anybody else have this issue?
UPDATE... looks like as long as i dont try to make a call the option to switch it back to auto is still there. One a call is attempted and fails the option to set to auto disappears.

Most carriers Phone calls and Texts dont go through LTE...... If your setting it to LTE only thats why.

I understand but after it's been on LTE for a while it doesn't give you the option to switch back.

Depending on what rom your using under mobile networks there is network selections with
LTE/WCDMA/GSM
GSM Only
WCDMA Only
and LTE only

Right, thats what normally the options are however after about 5 min after selecting LTE/CDMA the only options that appear were.
LTE/CDMA
CDMA

How are you changing it? Changing it via Build.Prop? Then there is your problem, JUST change it using the setting under mobile networks..

Stop changing it to lte/cdma and you're phone will no longer mess up. Leave it on gsm/wcdma/lte auto. You're phone will switch when the appropriate network is available!!!

Simple fix. Just select airplane mode for a few and then toggle it off and you'll see your network options come back once data roaming turns off and your carrier logo appears. I typically run lte/CDMA to get consistent lte speed bit when a callsade I have the same issue as you. But I just gave your the fix so your good

Thanks a lot captain obvious, the point of the thread wasn't to "not switch it" dude, it's finding a work around and make everybody aware of what happens.

This seems to be the only issue. Do I need to change some settings somewhere after flashing or should I just try to reflash the whole thing.

T-mobile lte is selected and the settings are filled out. What could have caused the lte to stop working? It doesn't seem to matter what I do.
When I flashed it, network mode was set to 4G. Changed it back to LTE and got back my LTE.

Ok I am back on the stock rom and I am still stuck on the edge network and my apn settings are greyed out but look ok. The network mode is on lte/wcdma/gsm and the status bar says 4g but I have no signal bars and extremely slow spped unless I am on wifi. I can get calls and texts though. Anything else important to solve this?
Sorry for double post but my imei number is 15 digits long if that matters.
LTE GONE
Bump... Having the same problem! Tried everything with respect to network mode, APNs, *#2263# and flashing different roms.
Although it worked at first, LTE disappeared on me out of the blue. Any ideas?
Hello there, I'm in need of your help again.
My SGH-M919 has a problem, it cannot connect to 3G/LTE (Not even EDGE). My carrier uses the 850 mHz band for GSM and 1900 mHz for UMTS, so the phone should be able to use them. The thing is, it doesn't. It only connects to GPRS and the signal is very erratic and weak (Usually 2-3 bars). Sometimes I get SMSs from my carrier saying that I missed like 5 calls when my phone never rang once. I live in a zone with good 3G coverage, so it's not the signal.
I'm currently rooted on Android 4.4.4 (NH7). I already tried selecting "1900 WCDMA" in the *#2263# service menu but that only causes the phone to lose all the signal (And it's a problem to change it back, without signal the service menu doesn't work and I cannot change the Network Mode in Settings).
I've tried to select "WCDMA only" mode before, but my signal just goes to zero (The circle with the slash) before changing back to "LTE/WCDMA/GSM (Auto connect)" automatically.
I also cannot use the Network Operators option. Using "Search now" makes it search for a few seconds before showing the message "Error while searching for networks". The "Select automatically" one shows the message "Unable to connect. Try later" and then connects back to my carrier (Movistar)
My APNs are configured (They did it themselves when I inserted the SIM, but I've configured them manually before). The SIM card works, I tried it in another phone and it got 3G immediately, I also tried another SIM card on the GS4, but the result was the same. Someone told me to upgrade to the latest firmware (NK2) while someone else told me to flash the MDL modem. (Is that even possible? I read something about KNOX blocking all downgrades after 4.3).
Since I couldn't find any direct solution to the problem, I'm recurring to you.
Thanks.
P.S: I didn't change the LTE Band Preference option in the Service Menu because the last time someone messed with it, my IMEI/Baseband went completely nuts, I thought the EFS got corrupted, but they magically appeared everytime I enabled the Airplane Mode (So I was able to select Automatic in the ServiceMenu and they got fixed). Also, I don't live in a LTE area although once during a very strong thunderstorm, I got 4G for a few minutes before going back to G).
*bump*
Any ideas?

I've tried with and without it, it doesn't make a difference anyway.
Does it show you have an ìmei # other than all zeros?
Don't post it just a yes or no.

My IMEI is fine, the phone connects to the carrier network but it stays on GPRS (and the signal is always dropping)

I'll try that later. Will I have to re-root and re-install TWRP after flashing NK2?
I have a similar problem with my M919 on the Tmobile network. Using the *#2263# menu I can not get mine to work on WCDMA (4G) either. I can chose GSM /LTE only and my phone works normally but no 4G signal. If I chose WCDMA I get no signal. I can see it trying to connect and immediately dropping the signal. If I choose any option with WCDMA included it has erratic signal and will lose the signal most of the time when I try to make a call. So basically I have the choices of GSM only or GSM/LTE only. Before I discovered the secret menu I was stuck with GSM only in the phone's settings. This has been going on for months. Tmobile changed my SIM card and it didn't help. I've rooted and unrooted my phone (using autoroot) and even tried different modems (even worse signals) and now am back to stock rooted NK2 firmware and modem. I have given up and decided to get another phone (not an S4). My wife's S3 gets great 4G signals in the same location by the way. I wonder if anyone knows why our phones can't use 4G. I am beginning to think it's a hardware problem but I'm way out of warranty on mine.
Hello,
since I updated my OnePlus 3 to the newest Resurrection Remix I have problems with LTE/4g. If i activate Mobile Data, i only get EDGE with a low bandwidth. I called my Mobile Provider and they said, that in my area LTE is working perfect. I eject the SIM Card and placed it into another smartphone and after two sec. i get LTE/4g with a high bandwith. A factory reset, returning to Stock Rom, deleting the APNs didnt work either. Is there any soultion fo this issue?
Maybe I crashed my modem ? Is it possible to flash everything back to Stock ?
Thanks
type *#*#4636#*#* in your phone dialer, phone info, scroll down and set prefered network type to LTE only. you will be unable to call while in this mode so do not have it turned on. just test it if your 4g works

well then your phone is broken or your service provider is messing up. but you already called them and they said that it was all ok on their side. so that means there is certainly something wrong with your phone
