I finally upgraded my phone after 4 years with the old htc one s.
So I am very used to flashing that phone and ones similar.
I got this at&t version of the LG G4 for use with T-Mobile (US).
It came unlocked and all I had to do was put my sim card in and talk and text worked. Then set up a new apn profile for T-Mobile and everything else seems to be working fine.
I am about to embark on the whole rooting and flashing a new rom on it.
Was just wondering if there was any advice to consider before diving in.
I have done a decent amount of rooting and from what I can see, this phone doesn't really look to hard for the most part.
I noticed that there are different sections on he development forum for the different carriers.
But I am going from one carrier to another and would rather have a T-Mobile rom as a base. ( it think I am going to use a mostly stock rom. Just to see what LG has to offer.)
Is there any problem with flashing a T-Mobile rom on the att phone? also a T-Mobile radio?
Forgive my noobness, its been a while. "This almost never happens"
Also any advice for the easiest rooting technique. maybe a good video to watch.
I will do the research. But a nudge in the right direction could save a lot of time.
Thanks.

I currently have a Galaxy S3, running rooted stock ICS for Tmobile - and I would like to switch over to ATT and keep the same phone, just flash the ATT JB stock firmware onto it (or a custom ROM), and whatever other flashes may be needed to make it work, or something along those lines. Is this even possible?
The only reason I would think it could work is that they are both GSM phones so the tech should essentially be the same right? And since it's rooted, switching the SIM shouldn't be an issue either, as I have done so when I am travelling.
Or are there other major diffs between the 2 s3's that I am missing which make this an impossible.
I have a friend who is looking to buy a new S3 from ATT, and I would just as soon sell him mine with their stock stuff on there if they are basically the same.
Many thanks in advance to any who can help shed light on this.
U have complete wrong idea brother. You cant just flash att s 3 rom on tmobile s 3.
Find some att based rom for tmobile s3 . i think we have some.
Its almost same hardware but not same network antenna. So you cant run att 4g on it.
Simply dont flash att rom on it unless its says for tmobile.

I always thought that Tmo (i was actually told this by tech support once) shares antennas/repeaters with ATT... so I guess they are just piping the 4G through a diff frequency or something, and the antenna isn't tuned to pick it up. damn.
are there any carriers it WILL work with?

The T999 supports at&t's 3G, just not their LTE (T999 doesn't support LTE period).
What was being told to you is don't flash an at&t baseband (radio), recovery, or full ROM to the phone or you risk a brick. Any of the ROMs marked *AROMA* have multi-carrier compatibility, you just choose the underlying device.

Sorry to say, but you are forgetting something, a stock rooted Tmobile Galaxy S3
is not compatible with the AT&T services as well as any of the AT&T roms.
You would need to UNLOCK the phone first before doing anything else.
Good Luck!

pardon my ignorance, but what is the diff between unlocking and rooting, and how can I go about doing it? Also, and this is an aside, the only way that i can find to change the IMEI of a T999 is by using an external box - there is no software-only method of doing this yet, correct?

To put it into simple terms,
Rooting a phone allows YOU to make changes to the phone which includes flashing roms as well as
allowing apps which require root access to work on your phone which are available at the play store.
But rooting has nothing to do with AT&T or any other carriers.
Unlocking a phone allows the phone to communicate with different carriers like AT&T and others.
Your phone does not need to be rooted to work with different carriers, it only needs to be Unlocked.
Also once the phone is unlocked you would need a AT&T Sim card for it to work.
Even an Unlocked Galaxy S3 will not work on AT&T unless you have a AT&T sim card.
There is absolutely no reason to change IMEI.

Good Luck with the phone.

This is what you need, a SIM Unlock - and it happens to be rather easy on the S3.

they are right. you need to unlock your phone. if you go into a store or call customer care they should be able to help you out with unlocking it. i used to work for tmobile and i remember unlocking a few peoples phones.
My wife won a new Verizon LG G4 by dropping her name in a box at a radio station promo. Unfortunately, we are on a Sprint family plan. I've unlocked, rooted and ran custom roms on my last several phones, so I'm somewhat familiar with the process, but I've never tried to move a phone to a different network. I've compared the bands/frequencies used by the 2 networks, and it seems to be compatible as far as the radio goes.
From reading this forum, it looks like we are waiting for LG to make it possible to unlock the bootloader? Then what? Just rooting, adding a recovery and loading a Sprint based ROM using a Sprint SIM card? Or will the Verizon LG G4 not ever work correctly on the Sprint network? Sorry if that's too basic of a question. Just trying to decide if I should sell/trade the Verizon phone and purchase a different phone for Sprint. I don't mind waiting a couple of months for developers to sort things out, but really just need confirmation that I'll eventually be able to use it on the Sprint network, assuming I don't brick it in the process. :cyclops:
Thanks.

They will not add each other's device IMEI into their Databases.

Did you figure this out? I would really like to know.

Get the unlock code from Verizon, then call sprint or into a corp store and have fun added to sprint. They do Verizon iphones allll the time and do other devices as well.

I ended up selling the new phone on ebay and buying a Sprint LG G4 with the $.

OK, so I have an opportunity to get an LG G5 LS992 Sprint model today for a decent price (under $60), with box, original cable, charger, accessories, 2 or 3 cases, looks to be in fairly good condition from the pictures. The girl selling it doesn't know how to answer most of the questions I have so certainly I can't get her to tell me what the ROM installed is by looking at the Settings - About phone info.
So here's my question: been doing some research today into the current situation and from what I gather, Sprint, in their infinite greedy and stupidity as usual, has found a way to block the ability to unlock the SIM for use with other carriers like T-Mobile (my carrier of choice). Apparently this started with ZVC and I have no idea which specific version of Android that is since there's a bunch of them around but I'm going to presume it's at least Android 7.0 Nougat.
I'm going to presume that if this phone does not have ZVC on it then it's safe to also presume that I would be able to do the SIM unlock and make use of it with T-Mobile so if anyone out there might be able to answer that I'd be eternally grateful.
As stated, I have no idea what firmware is currently on the device, unfortunately, I sure hope it's not ZVC or anything later, guess I'll find out later today when I meet up with this person.
Dammit, Sprint, what the hell are you people doing?
It has been a while since I've spent time on XDA. I haven't flashed a phone since the HTC One M7. I had to switch carriers from T-mobile to AT&T not long after I had purchased the S20+ for T-mobile. Most of the features work on AT&T, but I'm lacking the VoLTE, Wifi Calling, and Visual Voicemail that I would really like to get working. Can someone recommend an up to date guide that can safely guide me through the process, I'm sure its not that complicated, but I have been away from the scene for a while and I really don't want to end up with a bricked device or accidentally pop an e-fuse (if thats still a thing).
I appreciate any help, advice, or direction that anyone can provide.
So, I have an LG G7 from a couple of years ago that came with G710ULM11g (BPT). And unless the phone manufacturer itself disables unlocking the bootloader, 99% of the phones my carrier offers are unlocked versions (ive been able to easily root every phone from them for years except for Samsung phones recently, they suck.) But After getting a different phone, I rooted the G7 and flashed it with G710ULM21f (BPT) stock rom. No problems. But i just recently accidentally smashed the LCD screen on my new phone and its unusable at the moment and I cant afford to fix/replace the screen currently. So, I took the SIM out of that phone and put it into the LG G7 and noticed that the antenna bars only displays "1x" next to it. So, I went on a deep dive researching spree the past few weeks to see how I could get the phone receiving 4g/VoLTE like it used to. After hours and hours of research and reading and re-reading xda threads, reddits, posts on other android forums, blogs, and watching countless videos, I still haven't figured it out. I tried changing the APN settings, changing LTE Field test settings in the service menu, adding the enabler file in root, and exploring the root files with ADB to no avail. I managed to screw the phone up multiple times to where I couldn't even get 1x though but always figured out how to get it back.
I also came across articles, threads and other posts on the internet from people claiming that once the G7 is rooted that it will no longer be 4g/VoLTE capable ever again. And then I came across 2 or 3 threads claiming that if you crossflash with the correct firmware that you can get 4g/VoLTE back on the phone. And I'm not sure which one to believe. BUT if the crossflashing threads are true then I would like to try it. My problem is that not only have I never crossflashed firmware on any of my phones before, and I have no clue which firmware to crossflash with which but I seriously can't understand some of the steps in the threads that I read. I know HOW to follow instructions and have flashed custom roms on past phones but some of the steps I'm confused on since they're not using terms that I'm typically used into flashing tutorials and I really don't want this phone to get hard bricked. So, if anyone could help me out with which firmware I need to crossflash according to my region while also explaining the steps a little better, I'd appreciate it.
I also came across info stating that some carriers will allow someone's sim to be put into another unlocked phone and it will work fine. While some other carriers activate their SIMs to be phone/imei specific. Now, I'm not exactly sure which of those my carrier does but I'm leaning towards the idea that they're SIMs can be put into other unlocked phones due to the fact that my G7 is technically working with the SIM as in I still get 1x and I can still send and receive calls and texts but I just can't receive 4g/VoLTE. So, I'm thinking that if its real, the crossflashing idea would be the way to go.
I feel like I'm forgetting to mention something else so if I remember it, I'll be coming back to edit/add to this post. But any help would be greatly appreciated!
Thanks!
