I have the same problem with my lg K7, it's a T-mobile device. Mine works only the 2G / EDGE BAND. I did unloked the bootloader, also tried build.props but nothing changed, it seems that the other bands are still locked by the manufactor.

Hi everybody.
I purchased a unlocked gsm optimus t (t-mobile) in USA last week. Well, in my country we have a 850/1900 wcdma band (it seems the same at USA), but, i can´t conect to 3G network.
Searching for the phone specs, i find it the optimus t work in 1700/2100 network, it´s that correct??. If the answer is yes, it is possible to change wcdma frequency in this phone??.
Thanks for you help.
Pd: I read if i install a correct firmware for my country (Chile) is possible to change it.
I don't think so. There are 2 versions of the phone. I've bought mine in Chile, and no matter what ROM I use, I still can connect to the 3G network.
However, I think you should keep your phone and wait for Nextel or VTR networks to become operational, which will work on those bands.
You should see those 3G networks doing a network search on your mobile.

I have a vodafone EU HTC ONE phone.
I have now moved to the US and am on T-Mobile.
However I can't get 4G/LTE on the phone no matter what I try (I've manually entered the fast apn)
Does anyone know if this is even possible?
Do I need to unlock the Bootloader, etc flash with the T-Mobile ROM, etc. ? Will this even work?
I do not think the Vodafone One has the T-Mobile LTE band built in. According to Wikipedia, TMo US uses the 1700MHz band for LTE. Your phone doesn't have a 1700MHz radio.
Haven't seen any post on this, but I got AWS working on a Bell LG G2(D803)
Added band support using QPST and connected to Wind no problem.
Care to share your method?
I roughly followed this: http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269
No need to root the phone, it goes into diag mode when you set the usb connection to PC mode.
I used 115868544 as my NV value. Not sure if you can add more bands but AWS was the only thing I was interested in.
Hi, I have tried Googling this but I still don't really know how this works.
I have a D800 that offers LTE 700 / 850 / 1700 / 1900 / 2100.
However, I need LTE 1800 for 4G in New Zealand.
Since Snapdragon 800s have modems on board, can I flash the bands for D802 and get 4G?
I don't really know about this so please help.
Thanks
I didn't mess around with any of the LTE bands, only the WCDMA bands.
I have tried changing WCDMA and LTE bands on my VZW VS980 being used on ATT network.
After several attempts, under different Roms and Kernels, I have been unsuccessful in changing either.
1877 NV value can be changed but leaves phone unusable while 6828 NV value changes do not stick after reboot.
If anyone has been successful in getting VZW branded G2 activated on ATT, please let know.
Here is a thread that has lot of information... Most of the changes, I found are reversible. So go at it...

Phone : LG K7 (K330) T-Mobile
Chipset : Qualcomm MSM8909 Snapdragon 210 (LTE model)
I tried to follow these guides : http://forum.xda-developers.com/z3-compact/general/guide-unlock-z3c-international-bands-t3091344 & http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269 in order to unlock all 3G & 4G bands because the phone was bought in US and now I'm in Europe.
The initial state was that phone could only operate at 2G networks in Europe.
I tried several combinations on the enabled bands, like all of them enabled, only the European ones, only a few etc etc but nothing worked. The phone could not detect the SIM at all, or at some occasions it was in a loop trying to connect and was showing the "welcome to <carrier>" pop-up without actually managing to connect to the network/cell at all. Even when all bands were enabled, the phone could not operate even at 2G network (that was initially working).
(I have checked after reboots etc that the new NV values are saved as should).
At all these failing states, the process qmuxd was running continuously at 100% cpu (if this info is at any help)
Now, I reverted it back to US bands, and it operates at 2G
My question is: since the chipset (as mentioned at its specs) can operate at these bands, shouldn't it work? Is there something else I should have in mind, that maybe prevents the phone/antenna from operating at European bands?
Thanx in advance
You have to contact the carrier. T-Mobile 1st to see what options are available to you (since it's a US Phone), and then call your current carrier provider if T-Mobile can not resolve this issue. Hope this helps you.

I have the same problem with my lg K7, it's a T-mobile device. Mine works only the 2G / EDGE BAND. I did unloked the bootloader, also tried build.props but nothing changed, it seems that the other bands are still locked by the manufactor.

It's an lg lte 4g model. i put here more software info.
android version 5.1.1
baseband version
MPSS.JO.1.0.c5.7
kernel version is 3.10.49
Software version K33010l
It does not work with certain bands because the flashed modem on the device doesn't support those bands. This is an OEM problem that would be fixed by a custom rom.
Hi I have a lg phone k7 The problem is that it does not support 4G or 3G only 2G so that my country where I live is a 4G signal please help me ???
