Any way of doing this without the LG Flash Tool, i dont have a backup because i accidentally deleted it. Can we theoretically just flash another rom that supports all variants like Vanir on our phone without the risk of bricking? Also, if i do go back is there any other way to unlock and use tmobile usa on the phone? I heard about the build.prop method but does that actually work for us carriers or only international?

You could flash to another rom if you would like too, but back to stock use this thread, http://forum.xda-developers.com/showthread.php?t=2432476
there are all the files you will need to return to complete stock, yes the build.prop method does work for US carriers, I have used it on my Sprint G2 and use simple mobile, a few bugs with it, only 3G data, wifi/hotspot doesn't work, +1 when you dial out, a few other minor things but over all, very easy and effective at using the phone on US service! Best of luck!

Try HERE. I suggest you read 1st couple of pages. I think JDSingle's ROMS on that thread are stock and have been modified for you. Also you will need root and modified recovery from HERE. If your wanting to use phone on a different carrier, your gonna have to unlock phone, totally different than changing roms, but you wil still need to be rooted and have custom recovery that I linked above. Read HERE for unlocking. ALSO Im not 100% sure this method will work as thread is for unlocking the Sprint version. Ask in that thread.
I didnt see this on the other thread about sim unlock for the original t-mobile S3 so my apologies if this method has been posted before.
I have tested this on SGH-T999L aka theLTE version of the S3 for T-Mobile. I did this on 4.1.2 and it will more likely not work on 4.3. I havent tested it on T999N (Metro PCS version) but if someone does and it works, let us know
1. Go to https://towelroot.com/ and download towelroot. Install it and run it. Now you are rooted.
2. Install RegionLock Away
http://forum.xda-developers.com/showthread.php?t=2470551
3. Run it and grant root and reboot and now you are unlocked.
Optional step
4. Update through Kies to 4.3 and it will work despite being rooted (Device Status shows "Official" if rooted through towelroot). Update fails if you do it through the settings so this is the only to update besides odin/flashing
I test it an AT&T Straight Talk and everything was working with LTE
Thanks! I had run Region Lock Away to confirm it was safe to try a while back, but was never able to test if it actually SIM unlocked the device. If it worked on 4.1.2, I think there is a good chance it would also work on 4.3. This needs confirmation though.
Also, SIM unlocking is permanent, so it should remain unlocked regardless of how you update or if you flash any custom roms.
It may also be possible to unlock 4.3 this way, I suggested a couple people to try this but they never replied with any feedback so don't know if it worked or not. This method works on the S4 with 4.3 but I think you have to downgrade the modem if I remember correctly, or it may only be needed for 4.4.2. The same might apply here
I am guessing that you need to have a stock based ROM. I attempted it with Carbon ROM and got "Could not locate CSC data!"
Yup, gotta be stock to unlock, whether you are using a dialer code or any other methods.

So, StockMod or S3Rx should work?
Not sure tbh. The dialer has to be unmodified stock. And I'm not certain if one of the system apps like keystring or factoryapp, or one of the others would be needed. Some custom roms debloated these, not sure about those two. (They probably didnt, but I can't say for sure. ) you could try it, but if it doesn't take, try flashing stock with Odin. Root66 should be ok if you do

I'll give it a try just to see if it works and give feedback,
The patch returns with Successful on S3Rx. I will have to wait til I get home to test it with another Sim card to see if it actually works.

Does not work on 4.3 build NC1.
I get a hold of alot of phones and work at cell phone repair shop so i always try to find ways to unlock them instead of wasting money on unlock codes. On the S4 you have to downgrade the modem and sometimes roms on 4.3/4.4 to unlocked them. So if we can downgrade the modem, i think we can unlock on 4.3.

Well, it wont brick, but downgrading the modem simply just doesnt work. No signal or anything. That's why the free unlock no longer works on 4.3.

Try it, I know downgrading modem to unlock works with the S4 but don't know about the S3, we haven't found anyone willing to do it, or provide the feedback
edit: well I meant unlocking with regionunlock

Dear LG Friends,
Long time XDA member, coming from the Windows Phone days HTC, then to Android HTC, bunch of Samsungs, and am now thinking about the LG space. More specifically moving from the Note 3 (T-Mobile US) running on the AT&T US, to the LG G3.
Before I do, I need some help from you guys. Which variant should I go for? I know my primary choices will be the T-Mobile and the AT&T variants (I believe they are 851 and 850)? Based on what's important to me, below, can you guys advise which variant to get?:
1. Development Support - Which variant has the MOST amount of Custom ROM options, that is on-going and kept current? I am spoiled with the Note 3, which has a massive development support. I have never tried the LG OS/Skin (escaping me what it's called), but if it's anything like the TouchWiz on Samsungs, I think it will be important to have CM/AOSP/AOKP and etc support.
2. This is related to # 1 - But I heard that only T-Mobile has the unlocked Bootloader? However, doing some research, I believe the AT&T and the Verizon and Sprint variants can also be unlocked? Is this true? If so, are they anymore limited than the factory unlocked T-Mobile variant?
3. LTE bands - I will most likely be using the phone on AT&T US, but if development options/support are higher on other variants, I might consider buying those models, even if they are missing some AT&T bands. For the Note 3 - T-Mobile is a Pentaband phone, meaning it had all the bands needed, so it could easily work on AT&T LTE, all the time. The reverse was not true.
And basically that is it. Initial instinct says to go chase the T-Mobile variant, based on my needs above. But please educate me and help me out if I have missed something. Thank you so much in advance!
Any input guys?

If you want OTA updates i suggest sticking with the AT&T variant since you have a valid AT&T sim. If you use a AT&T sim in a T-Mobile variant you wont ever get OTA updates and that means missing out on necessary fixes
1. All 3 US Variants are mostly the same, all have CM12 and all the random obscure AOSP roms as well
2. Well unlocked bootloader isnt that fancy it just means theres fastboot mode compared with the other editions where fastboot mode doesnt work properly even if you enable it. It essentially just makes installing TWRP easier since you dont have to root before installing it unlike other variants
Nevertheless Lollipop can be rooted on all US Variants right now really easily. But the only downside to it is that removing custom roms sometimes can be a pain since you have to use a way where it sometimes works and sometimes doesnt

Hi Friend,
Thanks for your response, this is very helpful!
No OTA is never a thing I consider. Everything that matters to me, is what I listed already.
So, is the development support (new ROMs, updates and etc) the same for all US variants or would you say one variant is particularly more popular?
As for the locked bootloader, I thought you needed an Unlocked bootloader to flash Custom ROMs, no? It seems like "Bump" fixes this for Verizon, Sprint, and AT&T and gets you TWRP on your phone, but do we need to do extra steps everything to the boot.img for non T-Mobile variants? Or is it a one time mod and then regular flashing and Backups with TWRP?
If it's the same for all variants after Bump, then you're right, I will likely stay with an AT&T variant, thanks to that Band 7 LTE.
Thank you again for your help, hopefully more can chime in !

No need for any steps. Its just install TWRP and your on your way to installing whatever rom you want
Unlocked bootloader means that the system doesnt security (consistency) checks on system partitions
For LG G3, its because someone cracked the encryption for the kitkat android bootloader which means people can sign non stock boot.img without having to worry about unlocking the bootloader.

Gotcha, thanks again mate! Another (hopefully last) question. If I buy G3, where someone had already OTA'd to 5.0+, will I still be able to root it, install TWRP and get KK ROMs, like CM11 or something?
And vice versa, if the phone comes with KK, do I need to patch with Bump and then I can install ROMs?
Thank you again!

You can root it but i dont know if installing TWRP will work. I didnt want to try it incase it doesnt work and it runs the factory reset script instead. That happened to me once before
But i would say just to be sure, downgrade back to KitKat to do it
Yeah, if the phone comes with KitKat just root, install TWRP using root permissions and then your on your way

This is helpful, once again bud. So how would I downgrade back to KK? Would I have to run a stock firmware of some sort? In Samsung, he Flash a .Tar file through their flashing tool called the Odin. Would that be similarly done here?
What is currently the best rom to flash for the pure stock experience that will work on Verizon? I am about to exchange my phone and wanted to flash this to try out before I get my replacement.
Is there a universal version yet?
The bootloader is locked, so flashing a custom ROM is not possible. I assume that is what you are talking about. There is a thread on rooting that you may want to take a look at. Haven't done it yet, but will after I get my replacement.

No I was actually talking about flashing a stock carrier rom. Who has the least bloat and changes? I flashed AT&T and it was OK but the voice didn't work right so I had to flash back.

The canadian rom is 100% stock. I can't get it to work on Verizon though
You think Samsung would supply a vanilla non bloat version we could flash. Would be a nice option. Honestly I don't think Samsung knows how terrible touch wiz runs on the snapdragon here in the states with all the bloat.
If you use the root method posted by OvrDriVE here
http://forum.xda-developers.com/showthread.php?t=3461232
You will have stock Verizon with Sprint recovery. After you're rooted, you can remove all the bloat you want or just disable it.
I've been seeing many other threads being created about this sort of topic and none of them really came to be useful in my sort of situation. I'm in a need of seeking help from anyone that could help me domestically (not internationally) perm. unlock my S4 without anything coming out of my pocket. The thing is, the S4 is locked towards MetroPCS and i'm unsure if T-Mobile will let me since both company's are considered to be one, but the phone is originally from Metro and not them, so I doubt they'll do it, I also doubt MetroPCS will let me either since I haven't had service directly with them for over a year, and this phone is extremely old. Any advice will be appreciated.
Which ROM is on the phone?
The only free method that may work would be to replace the phone's current modem to the 4.2.2 modem, root, run regionlockaway, flash back to the phone's current modem.

That seems useful actually, will try as soon as possible. Also i'm on the stock 4.4.4 ROM, so things should run more better. Thanks for the help
Edit: I haven't had any luck to grab the 4.2.2 modem and fw from any other providers. Do you know anywhere I could get the modem off of? Thanks
