4g open bands with non stock rom - Verizon LG G3

Hello,
I bought a refubnished lg g3 from ebay and by a mistake got a verizon vs985 version instead of d855.
now, i was able to open other 4g bands on stock rom using verizon hidden menu,
but is there a way to open 4g lte bands on custom rom?
or there is any custom rom that all 4g bands are open?
or some steps im able to do that finally i will get a custom rom with 4g bands open?
Thanks a lot!

No I don't think so, from what I've read.

I pretty sure it is possible.
when i got the phone it was rooted with custom rom and 4g, though it was a bad custom rom so i replaced it.
More than that, i've seen a video in youtube that parandroid rom open 4g bands with the g2 vs980. so maybe an AOSP rom will do the job, but im not sure which one of them.
anyone?
thanks

what about this one:
http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
according to the guide it will enable open 3g and 4g bands.
someone has tried it?

This thread has about the same details but it was easier for me to follow. I did successfully add all bands to a vs985. Proven by having access to band 12 with a T-Mobile SIM in my screenshot.

thanks for sharing your experience.
Can you let us know what rom are you using?
what kernel?
Thanks!

Kernal and ROM do not matter for this method.

Need info on LG G2 D800 ATT on MetroPCS

Hi, I bought an ATT Unlocked D800 LG G2. I am using it on the MetroPCS network and all features work. I have 4G LTE working well. I dont want the ATT Firmware on it. Is there a way I can install the MetroPCS Firmware on it? or Tmobile Firmware? I want to do this so I ca get the WiFi calling feature and other MetroPCS apps that are not on the ATT Firmware.
I have the LG flash tool installed but when I try to flash my G2 D800 with the Tmobile D801 Firmware it gives me an error. Ive been reading everywhere but cant find an answer. Any help would be appreciated.
Thanks G..

Sorry to ask but, how did you manage to get 4G LTE from Metro on your D800? I am about to purchase an unlocked secondhand one but I want to make sure I will get 4G speeds with my current plan ($40 Most Affordable).

[q] Verizon G3 Owners some questions

Hey guys I bought this Verizon G3 for a friend he wants to give it to his family in Europe.
I downgraded to 23C so far and want to install TWRP etc. On T-Mobile G3 it's much easier as just rooting and using TWRP manager and flashing whatever I want.
Anyways after I flash TWRP I can use any rom I want ? or the rom has to be specific for bootloader for example? on T-Mobile G3 I could flash pretty much any rom but one stock where I needed to flash modem+bootloader,then it worked fine.
Also if it safe to unlock the LTE bands? since the phone would be used in Europe that would be very nice to have European LTE bands.
Thanks!

flash the t-mobile firmware to the verizon lg g5

Hi, could I flash the t-mobile firmware file or rom to the verizon lg g5? I switched to t-mobile, and am able to use the verizon phone, but lte drops to 3g for calls and lots of the time data shows up as hspa when I check the icon. If it can be done, please explain how. Thanks in advance.
No you can't flash the T Mobile firmware.
other firmwares beeing flashed on different lg g5's
So, there is no way to flash different firmwares on the verizon model, just other ones. Is this because the bootloader is locked? How can people flash a different region firmware on some of the models?
I to am curious on this, i have called LG and was told that the only difference between the T-Mobile and the Verizon LG G5, was software based, and that their was no hardware differences at all.
If that is true, why would we not be able to flash the T-Mobile rom onto our verizon phone?
DO NOT ATTEMPT THIS OR YOU WILL BRICK YOUR PHONE BEYOND ANY REPAIR. It has been said MANY times before, google it first

The hardware is essentially different... Has nothing to do with locked bootloader, u could still use LGUP to flash regardless but it would likely brick your phone. Drops to 3g because of the bands used, there may be a workaround but it's unlikely.

Is it possible to modify 4G bands support by flashing Radio from E975 (International)

I am using an unlocked AT&T E970. But in my country(India), 4G operators use a different frequency for LTE (Band 3, 5 and 40). So I am not able to use LTE in my phone, but the E975 (International) version sold here in India works fine with all LTE bands. So.. I was wondering is it possible to flash just the Radio from E975 into this phone. I am willing to give it a try. If this is possible, then can you guys tell me where can I find such a flashable radio file from E975?
I tried flashing a custom ROM (Sling Kahroba) built for E975 into my E970. But, it didn't work.
I tried unlocking bands by changing NV values., but no luck . I wanted band 3 or 5 or 40 .
I am on Nitrogen OS Geeb.
Plz help us changing band i am also not receiving the lte network in jio sim

I too am from India and have an LG E975 but JIO 4g doesn't seem to work in my phone and i can't test other operators (SIMs) because its the only one available here (J&K).. Can you guide me to make jio 4g work with my phone... I'll be greatly thankful...

Not sure I quite understand the context of your question. Going from MM to N Roms should not impact your cell network connection.
i dont understand why it is doing it either but the main question is ifit is cdma or not cause i see alot of xt1526 post in cdma but i am running a sunrai rom and it is working

Surnia is the code name for all variants of the Moto E 2 LTE. Some are CDMA, some are GSM, some overlap. The xt1526 that you have has both CDMA and GSM bands. Other model numbers of surnia are xt1521, xt1527 and xt1528. The non LTE version is code name OTUS. Any surnia ROM is compatible with your device. You may need to reconfigure your APN settings after flashing though - that is the first place I'd look for network issues.
