[Q] LTE not working

My stock, unrooted SGN3's LTE is not working. This may be a T-Mobile issue. I know when I had a rooted LG G2, this helped me: forum.xda-developers.com/showthread.php?t=2494803
Is there any fix like this for the N3?

Settings -> connections tab -> more networks -> mobile networks -> network mode
Select what you want.
If you have LTE already selected and you don't have LTE, you are either in a non LTE area or you have a phone issue, call T-Mobile.

Nope. They'll let you lock out LTE, but the mode options are as follows:
GSM/WCDMA/LTE Auto
GSM/WCDMA Auto (no LTE)
WCDMA Only (No GSM or LTE)
GSM Only (No WCDMA or LTE)
I was happy to find this much, I came from AT&T, which doesn't let you do any of this. Given T-Mobile's incomplete LTE deployment, I can understand not putting in an LTE Only option, they're not going to be fully deployed until mid 2015.
Maybe once they're more deployed they'll add an LTE Only option.

LTE only would give you data only. You need hspa for voice. Until voice over LTE is regular, you won't see this option

Data is all I need. Was just curious. Maybe once CM hits the G3. Thanks for all the feedback.

Hi
Open the dialer and inter this numbers:
3845#*851#
Then choose:
LTE-Only > modem setting > RAT Selection > LTE Only
if u having other models like D855 - D856 - D858 or any LG device running android lollipop u can use this method
3845#*Your model#

@al5zMri thanks a lot man!!! This works on d855 i have unlimited LTE data plan but... only LTE -_- so it was incredibly annoying to constantly check connection mode while downloading. Now i wont waste money anymore!!!

Hi. It worked well on my G3-855, to force LTE only. But once the phone is forced to LTE only , now how to go back to the menu to cancel the "LTE only" if I need to registrer on an GSM or a 3G network ? Now once it's on "LTE only" which works fine for LTE, I can't enter anymore the hidden menu, the phone dosen't "dial" any number as it can't find a network to dial on. LTE is considered as a not dialing mode - it's data only. Thanks.

Lg stylus two dual
How can I get this to work for my lg stylus 2 dual.... I can't force lte only... Network disappear so quick ​the given code doesn't work for my phn

Disable 2G (LTE/UMTS only) solution

Sometimes the phone jump to 2G (EDGE) for no reason while HSPA and LTE work perfectly.
Here is the solution (and it will stay after power cycle):
Dial *#*#4636#*#*
Phone Information
Scroll down to network mode and choose "LTE/WCDMA"
Reboot the phone immediately.
This method works for me.

Almost, its *#*#4636#*#*

Trying to do this on my D855 international G3, on lollipop, but can't get into the phone information .
*#*#4636#*#* works, but when I click on Phone Information, an error is given 'note this application does not work on this device' . I suspect a changed lollipop radio/Rom thing.
Any idea on how to achieve this another way?

Did you manage to fix it?

is there a solution for this on asop (euphoria 7/06)?.... after a call it goes to 2g and it "never" switches back to lte

New method:
Dial 277634#*# and you can get in Hidden Menu -> RAT Selection.

Typing 3856#*855# into the dialer allowed be in, then choose LTE, then RAT options.

Using the G3 D850 (AT&T) for t-mobile but it rarely conects to 4G LTE, it's usually on 2G, tried doing the above, with the *#*#4636#*#* code came up a error that I can't access that app, and in the hidden menu I couldnt find where/how to set WCDMA or LTE only, any new way to do this?

Qwerty when in hidden menu choose LTE-ONLY > then >modem setting> then > rat selection works on my g3

[Q] ARTMOD v7 Network Mode fix?

I have problem getting 4G/LTE connectivity on ARTMOD v7 bcs Network Mode keeps changing back to GSM/WCDMA preferred, but if i change it to GSM/WCDMA/LTE auto my phone connects to 4G/LTE but seconds later Network Mode switches back to GSM/WCDMA preferred so my LG Optimus E975 jumps to H/H+ instead of 4G/LTE is there a way to fix this?
and yes i tried to set LTE Only in LG's Service menu called "Hidden Menu" ---> LTE-Only --> Modem Settings --> RAT Selection LTE Only but than i only get 2G connectivity and i bet it's bcs the Network Mode keeps restting to GSM/WCDMA preferred.

Flash European software?

Hey guys, apologies if this has been asked before or if this is a silly question.
I recently bought an Asian Lg G3 d855. The software version is D85510e-GLOBAL-COM.
The phone is working fine apart from not having any 4g connectivity. I have went into settings and tried to change to GSM/WCDMA/LTE auto but it doesn't connect to 4g and switches back to GSM/WCDMA auto as soon as I exit the screen.
I have also went into the hidden menu, to LTE ONLY, RAT selection and tried to change it there but still no 4g. If I choose "LTE only" I lose my signal completely.
I have also went into band selection and chosen band 20, as this is the LTE band for my network in the UK (O2). It says success when I click on it but still no 4g.
My question is, is it possible to flash a European software version and would this enable the 4g?
Or is there any other way to enable 4g on this phone?
Thanks in advance!
