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.
Ive tried that

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
I got this phone off ebay for a deal 330$. My plan was to root and install an aosp rom.
I have rooted the phone but cannot find anyway to install twrp. Seems like all the twrp recoveries and custom roms are for tmobile and international versions
i was not aware when i bought this phone that it would be a us cellular version the ad did not say
anyways what are my options? Is it possible to get an aosp rom on this version of the phone any advice would greatly be
appreciated
Unfortunately there are no options as of now. The bootloader is locked and there hasn't been a workaround discovered for it yet like for other devices.
At best you can root and flash xposed on the phone as long as it has Lollipop, but as it looks now, you won't be able to keep root if you upgrade to Marshmallow.

thanks for the reply, i can stop searching like a fool lol
will i even get the marshmallow update, i have a us cellular version running on att network
The US Cellular model will most likely get MM soon, but if you're on the AT&T network, you won't get the OTA. I'm not sure if you would have to put a US Cellular SIM back in temporarily to get the OTA download, or if you could just remove the AT&T SIM and download it over WiFi. Otherwise, you could just get the kdz when it comes out, plug into your computer and force the update that way.

yah but even with the mm kdz file comes out it will be for us cellular and the phone will become carrier locked and i will have to go thru the hassle if getting unlocked. btw my firmware version is us99110a i bought it off ebay. the seller did not specify it was under any network just said network unlocked. but like i said my firmmware version is us99110a which i believe is a us cellular firmware
US991 Marshmellow
Hi Guys,
I am having a real issue here after reading this tread. I recently upgraded to marshmellow but my data stopped working. I cannot get the H+ anymore. I need to go back to lillipop. I am looking all over the internet trying to find out how i can roll back. i even factory reset the phone but is goes back to marshmellow. do you have a clue how i can do it?
I asked around and they directed me to http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
My software version is US99120c.
Can I get help rooting the 10a? Every tutorial I see is 10c and I can''t update mine.
I've got a brand new 'unlocked' LG G3 D851 from ebay, IMEI# confirmed by TMobile, and it's on 4.4.2.. . Everything works, 4G LTE, wifi calling, etc. and it did couple small OTA updates from TMobile, but won't do any more updates, showing 'System is up to date'. I've already tried hard resetting the device, installed LG support tool software, still showing the 'system is up to date' with the old firmware# need some help with this, thanks in advance.

probably it is because after while they stop giving updates since a new one to marshmallow is in the works
I sure hope so... but tmobile tech said that the newer updates are still available, just not sure why my G3 wouldn't get them.
With the support tool open, select the options button, then choose upgrade recovery.
Hello,
I tried everything to unlock SGH-M919 - M919TMBFOK3 , The most popular way I tried was to downgrade to 4.4.2 then root it with chainfire, downgrading the modemsto MDL then using regionlock away and the *#0011# sequence as in this thread:
http://forum.xda-developers.com/galaxy-s4-tmobile/general/unlock-method-m919-m919n-t3138503
However, I still can't get my phone to work with other sim cards. Even though I don't get the interface asking for a code to unlock it after I reboot, it still says invalid sim card.
Is there any definite way to solving my problem? I would be very grateful for your help!
Is there a reason you can't use an unlock code from TMo? The phone being this old, plus you explaining you're doing it to use it outside the US, I'm pretty sure TMo will hook you up with a code that works in stock.
The reason I ask is because I had the same issue a year ago when I travelled to the UK for work. I felt naked without Google Maps :crying:
Once the phone is running 4.3 or newer bootloader, you can't use the dialler method.
Yes, downgrade to stock 4.4.2, downgrade modem, root, run regionlockaway, flash stock rom, and phone should be network unlock.
Hello, I have the Sprint Ls990 model, I was on a nougat custom rom, I lost root somehow so I decided to flash stock zv4 firmware so I could root. After booting up, I am stuck on hands free activation screen. Only other option I have is emergency call. I don't have sprint sim so maybe thats why. IS there any work around for this?
oops I figured it out. Please delete this thread.
