[Q] AOKP (JellyBean) ROM LTE issue

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.

I also have this issue but when i enter that in phone dialer it said "unfortunately the function has stopped"

LTE/CDMA 3G/4G Setting Stuck on WCDMA Preffered

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.

[Q] No Signal (Practically)

I just modded my phone (unlocked, custom recovery, s-off, super cid) but now that I have a custom rom I have no service. Well it says I have a couple bars but its basically just the basics I can call and text but no internet. I tried flashing the tmobile radio but that didnt fix it. I was using paranoid android but I noticed the problem so I tried a different rom but Im still having the same problem. Does anyone know a fix for this?
Also in my settings it says "Mobile network state: Disconnected"

Check your Apn settings ?

I had the same as your Nº 1 Problem, i tried to go to *#*#4636#*#* and force the phone to change to 3g but it didn't work either.
So i went back to my previous rom (XenonHD 5.1.1) y enter the menu on *#*#4636#*#* and select wcdma prefered (and i dis change).
I flash again CM 13, and the phone got 3g, but i can`t change the network mode, so i only got 3g or 2g.
i think that the rom doesn`t actually have the right permissions to change that now, hope it gets solved.
Hope you find this helpfull. And sorry if i misspelled some word, english is not my home language.

Thanks i got clearly. Not my home language too

1. As for your signal problem, depends on your carrier as CM is trying to be universally available to all carriers.
2. And as for the "invalid number" error, it is a very well known CM 13 issue according to CM moderators and developers and has been pushed to get fixed in upcoming nightly releases.

Preferred network type won't change

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?
