Hi all ,
Im experiencing strange problem in connecting my phone to 4g LTE.
I brought LG G3 International version(D855) with 5.0 recently, where Im unable to get the 4g connection, right now I'm able to see only 'H'. I also see that there is no option of 4g in network mode, moreover i tried all the hidden settings (*#*#4636 ,... and some other codes like 3845#*855# but doesn't work)
I have gsm/wcdma option only !!
Could anyone help me ?!!
hi
I went to Hidden Menu by typing 3845#*855# ---> LTE-Only ---> Modem Settings ---> RAT Selection ---> GSM/WCDMA/LTE auto, and it worked for me. i can see 4g on my data connection.

I tried this but in the network mode it doesn't appear "GSM/WCDMA/LTE auto"
I have updated the android 5.0 and have that option in my network mode.
I don't have further information to help.

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.

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

Worked for me,cheers.
So I decided to mess around with the hidden menu on the G3 and evidently I did something I was unaware of. My issue is i cannot get an lte data connection now. I have contacted att and my account is setup correctly so It must be something i did while in the hidden menu. I have no idea what though as i thought i didnt do anything. On my old note 3 If you messed up stuff in the hidden menu there was a dialer code that would undo all of it. Is there something like this for the g3? I have tried restoring back to stock to no avail.
Also when i was on cloudy 2.2 i couldnt select gms/wcdma/lte auto. if that means anything.
Any help or suggestions would be great
so im guessing u have att lg g3. on the hidden menu:
LTE Only>Modem Settings>RAT Selection
Choose : GSM / WCDMA / LTE Auto
i dont have RAT selection

i finally got to it but when i try and select any option with LTE in it it says failed. Any ideas?
When i bought D855p it came with 4.4, then i updated to 5.1, all official. After this i installed Cyanogenmod 12.1 and everything were fine. But when i installed 6.0(poland) my network signal keeps droping the intire day, it changes to UMTS and HSPA. I cant use my phone as a phone. The only way to solve this is, every time that i turn off the cel or put in airplane mode, is enter in MOBILE NETWORKS > NETWORK OPERATORS > SEARCH NETWORKS and choose GSM. (but i need to do this EEEEEVERY TIME that my cel turns off/airplane mode).
6.0 is the only ROM that i can choose GSM and the signal keep ~stable~. At least i can use my phone as a phone !
I did a backup of my IMEI before installing cm12 as well.
Things that i already tried :
-Flash ALL modem (ALL) , including 21C.
-intall cm13 and after cm12. Using TWRP 2.8 and 3.0.
-stock 4.4 , 5.0 , 5.1 and again 6.0. Using LGFlashTools
-MANY factory resets and wipes !
anybody can help me ? :good:
Same issue. I am on stock 4.4 and mobile network signal keeps dropping on weak signal area. I set to gsm/edge mode to mobile network. But nothing goes fine.

Doesn't work , sadly :crying:
i also tried to put in Network mode : GSM/WCDMA ( worked ) but when i choose GSM/WCDMA/LTE auto , signal drops every time. It is a solution to do this, but i cant use my LTE, and it sucks ...
Disable VOLTE n go to ur models service menu (check google) for me it was
*#546368#*851# (my model = d851)
*#546368#*XXX# (ur model=D8XX) verizon sprint numbers are differently
go to field test >network mode>set GSM permanently (try different gsm 850,990,etc)
Back > RAT selection > select GSM
U cant have network problems now cuz ur permanently set to gsm dont use 3g or 4g use wifi
hit like it helps

I'm sad to hear that. Try also flashing modem 21C. There are also other guides for restoring your signal around the forum, different things seem to work for different people.
