Ok so this is still a work in progress but it works, and lte works on my att and tmobile sims. Ill post as many screen shots and be detailed as I possibly can so bear with me.....
So i have a samsung galaxy s4 the sgh-s970g, and a customer needed it unlocked so I thought I would give it a try. Its been a fun phone to mess with. So I am on 4.2.2 and this is the only version I have tested on. I havent tested on 4.3 so let me know if it works for you.
So my baseband is MH3. I used saferoot to root the phone and then I used the twrp for the m919 version to get a custom recovery. after this i went into recovery and made a nandroid. I would advice you do the same if your going to try this, because I am in no way responsible for anything that happens to your phone it will trip your knox counter and your warranty is now void.
ok so I have a tmobile sim in the phone the whole time because it gives you a invalid sim message and when you get rid of that the phone is unlocked. Now I flashed the wicked v-8 4.2.2 custom m919 rom onto the phone. And after that i booted it up like normal and had no problems booting it. So when it finally boots up this is what I see....
know with the tmobile rom it is asking for a sim unlock code. This is where it gets a little tricky.. Youll need to download region lock.apk
you can get it from the play store or from the developer on xda, (great app by the way). So now is when i procedded to use spt box to unlock part of this but i believe you can do it without the spt. so just set your phone up and when your done your settings should look like this... youll still have straight talk radio but everything else including kernel is the tmobile m919.
Ok so now go ahead and open up the region unlock apk and instead of pressing unlock your going to lock it. when its done go ahead and reboot it and then its going to ask your for a password again but this time you know it.. Its going to be 00000000, or atleast it was for me but like I said i dont believe spt is needed to reset the efs i believe the region lock apk will do this and it shoould say unlock succesful like this...
the only kicker is anytime you reboot your phone your going to have to run region lock and lock your modem and then reboot and type in the 8 zeros to unlock if someone figures out a better way that would be awesome.. I also believe this method could be used to help unlock the s4 l720t and sm-n900p without the assisstance of sprint. Any feedback and help would be greatly appreciated and enjoy your unlocked phone....

Region away app works only up to 4.3, so I guess you need to downgrade the baseband to L720T's MK3 modem.
No harm in trying.

the l720t was actually shipped with a 4.2.2 rom and if you could find that modem for the 4.2.2 it was originally shipped with you can unlock it

I can only find a 4.3 ROM for L720T not any version before it.
So, just to clarify, do we have to use the ROM or can we do this on stock? I have two of these LTE-T marked phones from Straight Talk that I'd like to use AT&T Straight Talk SIMs with.
tried this on a stock tmobile mdl firmware with the mh3 baseband with no go.. What am i doing wrong?
Has anyone been able to unlock these tracfone devices officially through a tracfone provided unlock code???

Yes i have, Tracfone will have to provide an update to fix the issue. Reason is that everytime you enter the code its accepted. But as soon as you reboot the phone it asks for the code again. So not sure how tracfone will handle this.
Well I returned my $250 Black Friday special as I just have no faith in getting an unlock code for these Galaxy S4s as I wanted to use it on AT&T and I had picked up the Tmobile version. I'll have to settled for a used item instead.
So will this phone work with a straight talk att Sim and a tmo Sim as long as its through ST?
After fallowing all the steps I get to the 8 0's hit enter and it just sits at the screen, and says unsuccessful. Sgh-s970g bb:mh3 av:4.2.2
Anyone know of a pay site to unlock this device. The one legit one was for over seas and I'm in US. I tried offering straight talk money and they said this phone needs to be active for 5 more months before they'll provide me the unlock code. I guess you need 12 months of active service to be eligible for the unlock program. The only thing is, is it will only work on a straight talk T-Mobile Sim until then. Tia.
It DOES work. I installed the wikid v8 rom on a SHG-S970G this morning, opened region lock, unlocked modem, relocked modem rebooted, and entered my unlock code and BAM, Successful unlock. Thanks a grand! By the way i bought the unlock code on a 3rd party site. Im now running ATT on the phone.
Straighttalk will only unlock phones purchased on or after Dec 2013, currently active on ST Service & have been active for 12 consecutive months, if you call the unlock department you will be transferred to their automated information center if your phone is not eligible for unlocking, this is just to inform you of the requirements to unlock your device.
ST unlock
I've had mine 6 months... Called them 5 times and they told me everytime they couldn't unlock my phone (sgh s970g). So.. I used CHIMURA to root for free. Installed the m919 twrp for recovery. Installed wikid v8 using twrp installed regionlockaway locked the modem rebooted, entered my unlock code and it gave me a successful unlock. As stated I'm running a Straighttalk AT&T sim on mine.
Extrapolate to S5?

Do you think a similar technique can be applied to a Galaxy S5 from Net10/TracFone? I tried to use a S902L with my (Canadian ) Rogers SIM card and unsurprisingly, it didn't accept it
Hi all,
I would like to start off by saying that i dont care about any warranty or any such issues. I had bought a S4 in US which i brought to India without ever activating on T Mobile network. This means that on contacting T Mobile, they are unable to send me any activation code which could SIM Unlock my device.
So now my only problem is to make my device usable. I see two options:
a) SIM Unlock
b) Complete removal of firmware and install some custom ROM, bootloader and other components to get rid of T mobile network
Problem is that i am a newbie and couldnt find any thread that could help me. MY device is updated to the latest version i.e. i am on 4.4.2 with baseband as M919UVUF9B4 and knox bootloader
Can someone help me out. I have already tried rooting the device and trying some apps which suggested that would help me unlock my device but none of them worked..
Thanks

If you paid T-Mobile the full price for the phone approx US$500-US$600 (not the subsidized price) before you left, they should provide you with the SIM Unlock code. You may need to talk with another customer service agent. However, if you only paid the subsidized price, then you've broken the contract with them, and they won't. You'll have to contact a company that will sell you an unlock code.
As to rooting the phone, have you tried this one: http://forum.xda-developers.com/showthread.php?t=2294005 ?
If this doesn't work, you're doing it wrong.

Flashing a custom rom will not allow it to work on a different network. The phone will still be sim locked.
Like the post above me says, call T Mobile and have them give you the code. If you didn't pay the phone off, they won't give it to you nor should they.
Chainfire's Region Lockaway app will SIM unlock in the process of removing region restrictions. I remember reading something to that effect anyway.
For use chainfire's Region Unlock, you must be root.

@Skipjacks & rlichtefeld: I have already tried calling T Mobile and they are not ready to provide me any unlock code since the phone was never used on the network. Yes, its paid in full but i am in India now and cannot do much from back here to fight with them.
Have already tried chainfire's Region Unlock but its unusable on 4.4.2.
Please suggest the ways in which i can unlock my phone which is on 4.4.2 with baseband as M919UVUF9B4 and knox bootloader and i request you to please do not assume that phone is blacklisted or the warranty be void. i just want my phone to work here and that's it.

id suggest you find a website that unlocks phones, it usually costs less than 10 bucks or probably like 500 or so rupees but it should save you a lot of headaches

I have a Samsung S3 I747 device. It is running ANdriod Version 4.3, I747UCUEMJB.
I wanted to unlock this and was wondering if this is possible. I went through lot of threads on this forum, but that left me confused and could not figure out if it is possible or it is not possible, without calling AT&T or without buying the unlock code.
There were some threads which said that we can go back to 4.1.1 or something. (I have been able to unlock the other phone which is running 4.1.2 but for this I cannot go back).
I am a newbie with phones and andriods, and hence was looking for simple instructions if any available to lock this 4.3 andriod that I have.
Any help would be greatly appreciated.
Once on 4.3 or later the free unlock method will not work. Only getting a code from the carrier or buying one online will.
So I'm currently in Europe and I will be here for 2 more months and I would like to unlock my phone because $4.19 a minute is ridiculous. However tmobile support is being, let's say very smart. The first representative said "just visit you're nearest tmobile store and we'll help you out there." After I had already told them I was in a country without tmobile. So I was wondering if there was any way to do this for free? I really don't want to have to spend any more money right now. I'm currently running liquidsmooth lollipops latest build. And I really don't want to have to revert to stock because I currently have Internet speeds of 85kb/s and that would take ages to download and then reset up my phone. All help is greatly appreciated.

Which version should i downgrade to, and could you give me a like to a method of unlocking it?
Before flashing any TW ROMs via Odin, confirm the bootloader and modem on your phone.
I'm not sure but if the T999 is like the i747 (ATT s3 version), you cannot downgrade the bootloader from 4.3 to a lower version. Doing so may brick the phone.
If you are on a 4.1.1 or 4.1.2 bootloader, you should be able to downgrade to stock 4.1.1 and you may be able to unlock for free using this method: http://forum.xda-developers.com/showthread.php?t=2014982
If you cannot downgrade to stock 4.1.1, you'll need to buy an unlock code and enter it using a stock Samsung dialler.
Hi all, I've been reading tons of threads and I am still having some difficulties with this phone. I am not in the US, I got this phone from a coworker that was going to throw it away and brought it with me to south america to give it to my friends mom who has no money, its and old phone but the one she has is even crappier ,I thought I would be able to just pop the SIM and get it going but nope.
If anyone could point me in the right direction I would really appreciate it, I have a few more days before I go back home and I would love to be able to leave this working for her.
Let me put you up to speed:
-Phone is running Android 4.3
-Phone was rooted using Odin, has SU and CWM
-Followed thread here to SIm unlock: https://forum.xda-developers.com/showthread.php?t=2023709 but #4 option is not present on 4.3
-I tried downgrading to 4.1.2 custom root666 to see if I could get #4 but to no avail since you cannot from this 4.3 version
-About to follow this thread :https://forum.xda-developers.com/showpost.php?p=48012926&postcount=8
but not sure if correct for what I want to do.
No more ideas, please help!
The phone can only be unlocked used an unlock code. Try contacting T-Mobile for a free unlock code or buy a code from eBay.
i'm with the same problem. i bought an sgh-i747 and after two months it bricked, so i replace the logical card (i don't remember how to say it in English, lol.) and boom!!! now i have a t999 and it doesn't work with movistar. (i'm from Venezuela)
but well, i've been reading posts about unlocking the phone and every one of them only works in JB 4.1.x. i don't know if i could unlock it by the downgrade process and i'm scared of getting the phone bricked again.
