Using the dialer code *#*#4636#*#* I have changed the setting from "LTE/GSM/WCDMA" to "WCDMA Preffered". I did this to see the difference in battery life being connected to HSPA+ & 3G compared to LTE which I was connected to before.
The Problem is the setting is stuck on "WCDMA Preffered". No matter what I do, when I select something with LTE in it if I exit the test menu and go back in with the dialer code it is back on "WCDMA Preffered".
Things I have tried:
1. Re-Flash ROM
2. Flash a different ROM
3. Re-Flash the Modem I747MVLLE8
4. About every possible combination of turning on/off the radio and disabling data connection and rebooting
I'm on Rogers running Ultimatum ROM and Faux's Kernel.
I'm hoping somebody knows of a way to get this setting back even if it involves flashing something with Odin or reformatting my phone or going back to 100% stock. Any help is greatly appreciated, thanks.

In case anyone encounters this I solved the problem by flashing cm10, which has a working toggle in the menu. Im sure using odin to flash the stock firmware would also work.

I'm in the same boat. For some odd reason my ATT S3 is unable to get LTE in any roms except LoserRom and Stock 4.0.1. Even when I update to stock 4.1.1 with Samsung Kies I an unable to get LTE. I've tried CM10 any many other roms, but can't get LTE on them. Also checked the network and mine is stuck on WCDMA Preferred. Unable to change. I would select LTE and it would change it right back even on CM10. Any ideas?
Did you try changing it using the menu in settings when on cm10 or stock JB? Instead of the dialer code.
I used the settings menu in cm10 to change it and the change stuck. Then I used Odin to flash the stock 4.1.1 firmware that I got from samfirmware and it stayed on LTE through that transition. There is also a setting for network mode in the menu's in 4.1.1
Other than that I'm out of ideas.

Yes i did try it on cm10 menu. I go ti the network selection and see it on wcdma preferred. Click it and select the lte. Right when i hit back it changes right back to wcdma preferred. In the stock 4.1.1 its not changeable. It says the default is selected. The only way i can see the options are if i pop the sim up but not out. The phone will say sim removed. When i go to the setting then the options are available.

Just happened to me.. changed it to WCDMA via *#*#4636#*#* and it is stuck there now.. any solutions??
I'm in a similar situation.
I flashed with SynergyROM and the Modem for Rogers and have lost LTE connectivity and the setting is stuck on WCDMA.
It's like punishment for being awesome.
Go to APN settings make up an APN.....then switch to it.....then quickly hit the dialer code *#*#4636#*#* and when you see the radio disconnect ("unknown" network)....switch the toggle.......tada!

There should be a pull down window after you go into device info. that should read lte/cmda/gsm if stock....it will read something else if its "stuck" on something else...

Go to [Settings -> More... -> Mobile Networks -> Network operators]
Click on ATT to reregister the network then switch it from lte to gsm/wcdma on Network Mode and it should work but after reboot you have to do it all over again.

Hi:
I installed the AOKP (Jellybean) ROM from http://forum.xda-developers.com/showthread.php?t=1766684
on my Telus (Canada) S3 SGH-I747M and I could not get the LTE/4G like I always got at home.
If I flash back the stock ROM then 4G/LTE came back. I checked the APN settings after installing the AOKP and it looks the same as the APN settings in the stock ROM. Please advise me how to get 4G/LTE on this rom or is there any Jellybean rom out there that I can get 4G on my Telus S3 ?
Other issue that I didn't like is that at times I had to press multiple times on the HOME button on my phone to wake up the phone, none of this issue happens on the stock rom.
Thanks

The only workaround I have found is to dial *#*#4636#*#* in the phone dialer and then going to phone information and selecting LTE only. For some reason it defaults to WCDMA.
I am currently researching some other info on this issue.
If you select LTE only you will not be able to make or receive calls. LTE is data only. You should choose GSM/LTE. The problem is in AOKP this setting resets after a reboot, so you have to do it every time you reboot your phone. The home button is a known issue, they're working on it.

How can I use only H+ on am soap ROM wit high flashing to a different tom then restoring to a backup...my phone hasn't been making backups correctly and I Dont want to try to restore a backup again till I want to flash another rom
The 3g APN that came with the ROM doesn't work..only the late one
Anyone? I'm desperate for a fix
I think is in Settings/more settings/mobile networks/network mode/ and choose your network. Those listed are LTE/GSM/WCDMA (Auto Mode), GSM only and WCDMA only. Hope this helps.

I am making the assumption you are on AT&T version of the SGS3 based off the fact that your profile shows you with AT&T. If this is the case before you select from network modes, you need to select "network operator". This will take several minutes to find them all and give you a selection. Once it finally populates, you can choose your carrier. I get 3 AT&T options on my phone so I just choose the first one. Selecting anything other than the AT&T network may not work. Once you have done this you should be able to make the network selection stick. This will only last until you reboot and you will need to redo the process over again. I do not know if switching Airplane mode on and off will cause the need to redo it but you can test it out to check.
Thanks! It works! Thanks for your help! i will only have to use this till I can make good backups again

Hey!
So my M919V has LTE disabled..basically doesn't have under mobile network and network mode: "LTE/GSM/WCDMA (auto connect)" .
I can't flash tmobile modem due to AUTH: Fail, and secure check fail.
I flashed stock, original i337M rom and it got me the LTE option: under mobile network and network mode: "LTE/GSM/WCDMA (auto connect)" .
then I flashed back the original M919V stock rom. I have the "LTE/GSM/WCDMA (auto connect)" option, but the rom naturally goes to "GSM/WCDMA (auto connect)" only, even though the LTE is present.
So, when i pick the LTE option and reboot phone, it switches back to GSM/WCDMA . How do I fix this, i want it to always stay at "LTE/GSM/WCDMA (auto connect)".
Please help?
im on stock original windmoile 4.2.2 firmware - M919V .

lol Thank you for that, i figured it !
So, i wrote that i only see "Bell internet" APN only.
so im connected to "4G" my rom doesnt say LTE idk why. but i have to manually connect it, like i said in my original post. but it switches to just GSM/WCDMA one after I reboo my phone.
I want it to stay at LTE/GSM/WCDMA, though.

The issue being why isn't the LTE setting locking in after Boot.
The LTE setting is there which you can manually set. But upon Reboot, you have to manually set it again?
Suggestion would be to ODIN Samsung Stock Firmware. Make sure the Firmware is for your ddevice.
ODINing back to stock will flash the stock ROM, Recovery, Kernel and Modem, and get you back to where you were prior to your issue.
If you're running a custom ROM/Recovery, install those afterwards.
But first see if your issues are resolved.

I'm not sure, although I've read about this happening before. To clarify, it used to auto lock, but now it isn't. Can you remember if you made any changes prior to the issue appearing?
App installs, Kernel changes, etc.
I understand you're on stock now, but were any changes made which caused the issue, which prompted you to flash Stock Firmware, but the issue remained?
Hi.
I have a Samsung Galaxy S3 T999 model on carrier T-mobile. Lately the phone has gone nuts and will get stuck on dialing out and will never make the call. Everything else works fine. Sometimes I have to soft reset, pull the battery and that will fix it for a call or two, then it will get stuck again. I have contacted T-mobile about this over 5 times and none of them can help. We tried to change the sim, reset the account. Etc and nothing. I have reset the cache, factory reset and even put in a good working sim card from another phone and the same problem comes up. During my latest troubleshooting I have narrowed it down to where I switch "network mode" to GSM only and that can make calls out all the time, but the data stays on E (which then I can't use the internet because it's so slow) When I switch back to auto I am sometimes able to place calls again, but only a few. After I test a few calls and leave the phone for a few minutes the phone will get stuck back on not making calls out and just saying "dialing".
Has anyone had the same problems or know of a fix? Currently I have been trying to flash the modem to different versions to see if that fixes the problem. The first two modems I have flashed did not work and came up with "unknown baseband".
If anyone can help I greatly appreciate it.
This is a known issue with 4.3.. What firmware are you on? Assuming you flashed the correct baseband for your device, the 'unknown baseband' message sounds like you are in 4.3 but what build? You can't flash any modems successfully less than 4.3

I was previously on 4.1.2 when the problem first started. I updated it to 4.3 and still the same problem.
jss15j.t999uvuenc2 build. (I put this one back on last night so at least I can use the phone today when I am at work)
I was just hoping that the device didn't go bad when it was on 4.1.2 because it was working just fine before the problem started.
Was it official update to NC2 by OTA/Odin or you just flashed a ROM?

NC2 was OTA. After doing some searches it said that OTA could of been corrupt, so I went and downloaded KIES and did a reinstall that way.
When I upgraded to 4.3 I tried that default baseband out and had the same problems. That is when I was searching on google and came across this forum and also the thread about flashing modems.

APN is epc.tmobile.com
Network Mode current set to GSM (the only way I can make calls out without the problem occuring)
WCDMA/GSM (Auto Connect) is what it should be on so my data is at 4G, but the calls is the problem here
I am not sure but can you check the settings of the Dialer to see if there is ways to choose Lookup providers ?

Nope don't see anything in the dialer about selecting a provider..
Its supposed to be something about Choose Lookup Providers. At least that's the way it is on AOSP.
I suggest Odin flashing the stock NC2 firmware and then factory resetting from stock recovery. (Backup first of course!) If it is still an issue, it will most likely be a hardware problem. From what you have said so far, I believe that you will find this to be the case. Could've been due to damage from a drop, or even overheating at some point. Or it could just be that its simply due to hardware degradation over time.
Hi,
I bought a 2nd hand G3 from a store recently and have noticed that under network settings even if I select GSM/WCDMA/LTE as soon as I leave the menu it reverts to GSM/WCDMA only. It sometimes finds and attaches to the 4G network but prefers the HSPA network and connects to that as a priority even if 4G is in the area.
I've done a rom flash with clear option and done a factory reset but that option continues to stay set to GSM/WCDMA so wondered if somebody had changed something in the hidden menus and that I might need to change it back and what setting might need changing?
I've tried 2 official rom flashes just to make sure it wasn't a bug, they are the 10G and the 10J roms, the 10J being whats installed now.
Any ideas anyone??
Go to dial press 3845#*your phones model and then press # like 3845#*855# then go to lte only and then go to modem settings and then rat selection and then choice what you want
Tried that makes no difference. As soon as you leave the menu it still reverts back

I have the exact same problem, after you choose GSM/WCDMA/LTE and exit the menu it goes back to GSM/WCDMA im on D855 with 10i not rooted.
Ok so it might be a software thing with the later builds? I'm on 10j at the moment and have done factory reset full reflash the lot, so thought it might be something that had previously been done in the hidden menu.

I was using 10a-eur before and everything was fine im using 10i-global wich i updated with lgflashtool, so im guessing either that is the problem (eur to global) or its with the update itself.
I'd guess then it's in the update 10i/j

If you do not want to root you could consider to flash it back to the v10 version that did not gave you any problems with it! But the most easy way is to root it using purpledrake and then install titanium backup and delete the lteconfig!

I agree with you! I flashed few days ago the10j files and I noticed that 2G/3G/4G was missing. Today I decided to reflash the D85510H_00. This .kdz files are suitable for my IMEI. I downladed from http://lg-firmware-rom.com/. Now 2G/3G/4G is active. I think that will help!
For those who aren't rooted, try NOT going into the "Mobile Networks" menu to switch to "GSM/WCDMA/LTE".
Try this instead.
-Go into dialer and dial in 3845#*855#
-Select "LTE-Only" and go into "Modem Settings"
-select "RAT Selection" and select "GSM / WCDMA /LTE auto"
See if this helps you retain LTE. If it does, do NOT go into "Mobile Networks" or switch to "2G only" because I have that it disables my LTE when I do that.

I tried that, it goes into 4g sometimes but it preferes 3g/2g conections for some reason, switched to 10h eur and it shows on the network menu lte enabled and it works fine.
