Phone: m919
Rom: CM11 Nightlies 2/4/14
Carrier: AT&T
Modem: Mk2 baseband w/Mdl non-hlos
I have searched and tried methods of trying to get LTE working by *#*#4636#*#* and selecting LTE/GSM auto (PRL) but the setting never sticks and it reverts back to GSM auto (PRL). I have also tried under settings/mobile networks/preferred network type to LTE/GSM/WCDMA and that always reverts to GSM/WCDMA auto. I also have tried different APN settings "ATT Phone" should be right although I have tried ATT LTE pta and ATT wap.cingular.
When I select the LTE options I do receive an LTE signal until I make a phone call or lose signal/reboot. It then switches to Hspa+ and never automatically back to LTE.
I first thought it was a hardware issue but I tried a GPE rom and LTE worked great! Too bad GPE isn't CM
I'm bummin... any ideas?

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.

Greetings, I'm not sure if anyone has encountered an issue with their network with Google 5.0 rom. Everything else works amazing, the only thing I've experienced is that the only way I'm able to get signal is when I toggle network mode to "GSM ONLY", it won't work with lte/wcdma/gsm or wcdma/gsm either. I re-downloaded and re-installed and still have the same issue. I reverted back to previous ROMS and the network works fine on both. The only thing I could think of is updating my modem but not sure. My current baseband version is M919UVUAMDL. Thank you for your time.
Update modem
Hello
After reboot phone setup wcdma/gsm network priority. There is also problem with changing to lte/wcdma/gms , you cannot click it directly, need first click like gsm and then lte to make it active.
Using official lolipop , IL customization
Anyone noticed 4G/LTE problem on Lolipop ?

I'm having the same problems, but I finally get LTE working
Same for me. But I don't have LTE yet. So didn't bother too much.
maybe you can try this:
FIX 4G PROBLEMS
edit build.prop
- look for 'telephony.lteOnCdmaDevice=0' and change it to 'telephony.lteOnCdmaDevice=1'
look for 'ro.semc.version.fs=GLOBAL-HSPA' and change it to 'ro.semc.version.fs=GLOBAL-LTE'
reboot your phone
type *#*#4636#*#*
Select phone informations (first menu)
turn off radio
in network prefered I've selected TD-SCDMA, LTE, CDMA, EvDO GSM/WCDMA
turn on radio again
exit
type *#*#4636#*#* again and look in network prefered, it will be on LTE/GSM auto (PRL) and 4G should be there
LTE/4G issue after hard reset
Hi to all,
and thank you for the tips doenen.
I have the same issue since i hard-reset the phone.
Just to be clear, if we want to edit the build.prop file, we have to be rooted ?

Hi, I did all the steps except the ro.semc one, because there is no such setting in my build.prop. However I still wasn't able to get 4g working, it just keeps switching back to the old settings.. Any ideas? Running cm12.1 android 5.1.1
Re issue with LTE/4G
Hello,
i got my phone back from SONY's technical services, cause i had a bunch of issue (i sent it twice in a month).
For now, the battery drain isseu seems to be fixed, but i do not have 4G/LTE.
I already encounter this issue, and after the service menu manipulation, everything got back in order.
I tried to do the same manipulations, but i can't turn off radio. It's like it was locked.
Any ideas ?
Thanks for helping.
Regards

Hi,
i'm currently running the latest CM13 and have a problem with the Preferred network type. It stays on "LTE (recommended)" and i can't change it to 3G or 2G. In Phone information (*#*#4636#*#*) it stays on "GSM only" and won't change to anything.
When i go back to LG's Stock 6.0 all changes work. With previous versions of CM13 (first 5 versions i think) it works also.
Does anyone have any idea?

I have the same issue on my LG G4 h815. I cleanly flashed the latest nightly of CM13 (cm-13.0-20160102-NIGHTLY-h815.zip), after first upgrading to the stock 20A image and installed TWRP. I flashed CM13 using TWRP. Then I flashed nano gapps. H+ is the fastest cell tech here, and my phone just can't use the cell network (it seems to connect, but never shows H+ and no data bits are routed). And when I went into the menu to select 3G as the preferred network, it won't let me change it from LTE. It clicks when I choose 3G and 2G, but the selection stays on LTE. When I go into the special menu for radio options, same thing, I can't select a different network mode (it simply stays on the current selection). Wifi works just fine, but cell phone use doesn't work -- no calls, no data. I also upgraded to the next nightly, but it didn't make any difference in behavior.
@Chipstepper Can you tell me which CM13 image worked? I'm going to try cm-13.0-20151125-NIGHTLY-h815.zip ..
Same Problem here on my Moto X 2014. I tried every CM13 nightly between Christmas and early January. I was never able to change the Radiobutton in Preferred Networks and connection in phone information was always GSM only. I also tried a clean flash of the cm-13.0-20160108 nightly, still the same problem.
Now I switched back to my CM12.1 backup where it's working.
Can somebody name a nightly where it's confirmed working?
The problem is that when the network settings are auto GSM / WCDMA / LTE doesn't work an Internet connection and when are set to auto GSM / WCDMA internet connection returns. The problem occurred on the 20D and 20B. At the CM13 everything works fine. I've tried to replace the list of APN but didn't help.
