unlock free proceed at your own risk!

Read all of the post and the one bellow it from cschmitt before you do anything. This also might be illegal in the USA if you bought your phone after 1/26/2013
The last few days it's been going around unlocking the note II and gs3 with some settings(http://forum.xda-developers.com/showpost.php?p=34661189). Well the good news is the method can be used on our phones! I don't know what modems work I know two that don't. I was able to use the T989 modem (Tmo_SGH-T989_UVLE1_radio.zip)to unlock my phone but others have reported UCLD2 (a skyrocket modem) works as well. after I unlocked I switched back to UCLI3 and the phone is still unlocked.
You'll need to be on a stock(or stock based) rom and you should make sure the number matches the text next to it. All you need to do is touch the row to select it. I did these steps with a O2 sim card in my phone. after the reboot your phone might take a second but it should connect to the network and be happy with your non att sim.
I have not tested this on a rogers phone. It might work it might make your phone explode in your hand and kill you. For all I know it could do the same for other ATT phones.

Confirmed, this method works to network unlock using stock UCLD2 rom and modems (the April 15th ICS 4.0.3 leak.) Links to the CWM-flashable stock ROM and modems can be found below. Unlock was performed on an AT&T locked SGH-I727 using a TMO SIM card.
This method is modem specific, as the service mode commands vary by modem. It does NOT work with UCLA3, UCLE2, or UCLF6 modems (NV initialize menu item is not present, or non-functional.)
Note: After 'Press [4] NW LOCK NV DATA INITIALLIZ' step the phone reports ' PERSO_NV_INIT is SUCCESSFUL', then it's safe to reboot.
Confirmed that IMEI is intact following network unlock, and that unlock persists following a ROM/modem flash (back to CM-10.0.0 and UCFL6 modems.)
Awesome find, my friend!

kool, i added this thread to the sticky, even though its cheap to buy an unlock code for rogers(i paid under $8 from ebay), for att users its more expensive

Hi, I'm stock ICS on ATT, if I just flash the new modem will that make any difference on my ATT service? Like not get HSPA+ service. I am currently out of the country so I can't test it with my ATT sim. (had my phone line suspended)
Also using a SIM from the Philippines... Will the type of SIM card make any difference?

First, a stock (or stock-based) ROM must be installed. Specifically, one that includes Samsung's serviceModeApp.apk in /system/app. This is required to support the *#197328640# dialer code that brings up the modem's service menu. ROM's such as CM9/CM10/AOKP/AOSP won't work for this because they don't have the service mode interface.
Second, a modem that supports the '[4] NW LOCK NV DATA INITIALIZE' command is required. The service mode menu items that are displayed and available are a function of the modem, not the ROM-- so only specific modems can be used to unlock with this method. So far it's confirmed that T-Mobile's UVLE1 and AT&T's UCLD2 have what it takes.
Just perform a nandroid backup of the current setup, flash an appropriate ROM and modem, factory reset, reboot, perform the network unlock, reboot, verify it's success with a non-accepted SIM, then restore the nandroid backup and re-flash the previous modem.

Great job on the research buddy working fabulous on my all my rockets 3 to be exact lol although i am a person who doesnt mind paying its always awesome to have a free method

Awesomeness. I paid to unlock my old SR but I returned it due to battery issues (long story.) Being able to unlock my new phone and force 2G networks in CM10 would be awesome. I'll try this when I get home.

Tried it with the UCLD2 modem/rom and idk if it worked... Tried twice. Both times this happened. Wiped again re flashed. Same result.

If you look at the OP he used ANOTHER sim card when doing all this. I think if you have an AT&T SIM in it doesn't work. I'm guessing that's it as I had an AT&T SIM in while I was doing it and it didn't work. Try a T-Mobile or other GSM sim and see what happens. I'll be doing that later.
Update: Apparently you do NOT need to have another SIM card in when you do this, as I was working on unlocking the phone with a T-Mobile card in and before I finished (I mean like I was on step 2) I got a T-mobile signal and was able to browse the web. Best advice I can give is when you reboot, make sure you wait for a good minute to see if the phone was unlocked, as you won't get a signal immediately even if it works.

WORKS ON ROGERS i727r
Just posting that I used the rom / modem posted in the 2nd post, and it worked great.
Thank you.

Worked like a dream.
Rocking a T-Mobile pre-paid SIM now.
Nice to have options.

Just did this about an hour ago it seemed to work c: recovered my backup and my service is fine. Gonna try on my brothers T-Mobile sim when I get home. Didn't flash another radio again though. Gonna try this one. I have constant text and call retrieving problems so yeah..

I would reflash the Hyperdrive ROM with no theme. I've had that happen a few times when applying a theme to my ROM. if you flash the Hyperdrive ROM and it still doesn't work I'd flash a different ROM.
After flashing, (of course after full wipe) test calls and messages and contacts apps. Then if you flash a mod or theme after that. Try your phone,text and contacts again. If they do not work, then your theme has borked them.

I have tried re flashing the ROM and still nothing i wiped everything that needed to be wiped before flashing and still nothing. I didn't think a theme would make this happen. But I guess another ROM wouldn't hurt to see if it works then. Will post back after and I might need some help though if it does not work

Go to System Settings > About Phone > Status. Under IMEI there should be a 15 digit number. If it's missing or just says 0 then you lost your IMEI, which is basically your phone's network ID number. Also is your phone number correct as listed in that menu?

Assuming you didn't make a back up, you're going to have to restore it. Here's the link to a tutorial: http://droidmodderx.com/galaxys3/?page_id=79
It is pretty involved so make sure you read the instructions carefully. Are you familiar with ODIN, because the first thing you have to do is flash back to a stock rooted ROM. Use this thread for that: http://forum.xda-developers.com/showthread.php?t=1762204
If you don't feel comfortable doing all of it I would get somebody that does. You can easily hard brick your phone using ODIN. Also, ODIN will completely erase your internal memory. So I would make a backup of any photos/files you need before proceeding.

He is right, getting your imei back is only halfway home. Your ERI should say 5 and under mobile network is should say Verzion Wireless.

GOOD NEWS I337 MF3 SIM unlock!

Just to be clear this may not be a permanent unlocking as I can't verify the results. (although I've had numerous times of restarting the phone and still good, but I am just repeating the developers words.)
All I know is that I have an i337 with the newly updated MF3 baseband, I tried everything and anything to get this guy unlocked since I am visiting overseas at the moment. I tried the 27663368378, the 0011, 9090 tricks and anything else you can think of, I even took it to one of the mobile service places and they were unable to even get an ack from the phone with it's new baseband. I tried downloading the "servicemode shortcut" from the play store and the only thing that app was able to tell me was that it only works with galaxy family (just as a reminder I have a galaxy s4!) I think whatever they had done, was even confusing the app, so it couldn't know its on a galaxy! anyways, after searching and searching I came across a link and conclusively an app called "RegionLock Away" by the chainfire group from the moment the app was installed it took 45 seconds for my phone to be unlocked up and registering to the network I am in right now.
As it's always been said, I don't take any responsibilities for anything that happens to your phone, as I believe they don't either, the only purpose for this thread was to inform some of the people like me that are willing to take the risk and enjoy the rewards or bear the pain if it succeeds or fails.
honestly, as I will myself when I get back in the states, consider donating to them or purchasing the app, since we need guys like these to save us in moments like these.

Give it a try b4 u make a statement. I tried it b4 and it worked.

I'm living in Romania, I bought an ATT S4 from USA and it was locked. I unlocked only the region with Region Lock Away and everything works. Maybe it helps someone.

Can confirm it works as well. It also seems to permanent. I've reflashed back to stock using ODIN and used Safestrap as well for GPE ROM and it stays "unlocked."

havent tried it yet, but thanks bro, you saved me 40-30 dollars!!
EDIT; just tried it. works perfectly!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I figured out a trick this worked on both of my galaxy s4's they are the I337M Canadian model.
DISCLAIMER I am not responsable for your phone if you can't follow basic instructions do not attempt.
First put your phone back to the proper Firmware where you can access service mode. Once that's done download QPST make sure the phone is on RNDIS+DM+MODEM download the phoneutil.apk put it on your phone and install.
Once that is done make a backup of your NV MAKE SURE YOU DO THIS IT SAVES YOUR IMEI NUMBER.
After the phone is rebooted go in to service mode and clear your EFS once the EFS is clear get to SHA256 on turn it on once on go back and then turn it off you should get 116630
Go back to COMMON and MAKE a backup
After the phone reboots open QPST and RESTORE the NV you had just backed up.
Your phone is now unlocked I CAN CONFIRM THIS WORKS.
Sorry the instructions aren't very precise but like I said IF YOU HAVE NO CLUE WHAT I WAS TALKING ABOUT DO NOT ATTEMPT.

Just to clarify, if you change modems, you will HAVE TO re-run the app, as it patches the modem, it is NOT a true unlock....so in theory Ends is right....still not bad, and it works, but changing modems will disable it....

[Q] 4.3 Root, out of ideas

Alright, I just started trying to root my galaxy s3 a little while ago. I searched how to root it, and I got a video where I needed to unlock the bootloader. I tried unlocking it using the video's method, not realizing it was horribly out of date. So, the bootloader has been patched for that, I decided to try saferoot, and the kernel is patched for that. It recommended I use another method of rooting, but I don't know of any.
What should I try?

[GUIDE] Straight Talk Galaxy S4 (S975L) running AT&T towers Guide and Info

If you are using the Straight Talk Galaxy S4 with build number
JSS15J.S975LUDUANB1 and just want root and simple recovery
You can root using towelroot.
SuperSU will also deactivate Knox.
Safestrap version 3.72 works for getting a proper recovery installed with the option at boot for system or recovery. Note that it will say safestrap is disabled but will still allow your choice to boot into recovery.
Make a backup in recovery as soon as you can.
Or if you want awesomeness!! Do THIS!!
Here is the definitive guide for those wondering what to do that will work and be stable and AWESOME!
From the beginning:
1.Root with towelroot (search) AND install SuperSU from the play store.
2.Install the latest recovery from here using the DD method listed directions from the TWRP site. This is from T-Mobile and works! http://forum.xda-developers.com/showthread.php?t=2263001
MAKE A BACKUP!!! DO IT! No more messing around with Safestrap and the bitter warnings!
To get into recovery hold "home+volume up" during boot. Whoooo!!!!
3. Install the Lollipop gpe ROM from here: http://forum.xda-developers.com/showthread.php?t=2539361
This uses the aroma installer and works well.
You may, or may not have to input *#6463*# into dialpad to change settings to LTE etc.. This adjustment may alsobe in the ROM settings!
4. Optional - install the googy kernel
I like this kernel better though there isn't a huge difference from the hulk kernel. Make sure to install the GE edition 1.3.0. NOT TOUCHWHIZ! : http://forum.xda-developers.com/showthread.php?t=2741181
ENJOY!

The zip to allow tethering WILL NOT work, and you will be stuck on the Samsung logo.
Xposed works well, but do not use the option in gravity box to add the recovery option to your power menu or your device will freeze upon pressing the power button.
Greenify works well.
Advise against ROM installation, as well as initial upgrade. You will lose app to SD ability if you upgrade.
The boot loader is not unlocked, so no cool kernels here

No not yet, I just got the phone so I haven't done a lot to it yet. I was able to get tethering working and it was pretty easy and I got a nice extended battery case for it yesterday that I love. Other than that I haven't had time to do a lot else to it.

See first post

I used tmo twrp. Flashed tmo and att roms. I also have the Odin file. I am not sure but I am on the s975L which I thought was att not sure but pretty sure. However it also says i337 underbattery ...I've tried more tmo roms than anything. No safestrap but I might try that later. Seems we don't have locked bootloader. This is great. However unlock is next for me. Having a blast hacking the hell out of it. So far I have had no issues. Again I'm not new to this. Lol. It's an addiction. I have sprint note 4 as my DD. So this is my fix. Lmao.

As far as I know, the bootloader IS locked, but can be bypassed using Loki to patch kernels for custom roms. Glad to see somebody else on this phone

That's strange. If it was locked I wonder how I've used tmo twrp no loki or SS and flashed tons of roms so far...I just odined back from a modem issue. But rerooted now off to get some modems etc...boot and all. I'll keep reporting. Thank you bro. I maintain many devices and carriers and am about to start a channel on YouTube. I do music writing now with keyboard. Now I'm just getting a hand on s4 straight talk and will make a list of all working roms.

True.. I don't know as much about it as I like. I just wasn't able to use fastboot or "unlock" using fastboot.
If you are working with the modems let me know how that goes, and maybe you can help with an issue I'm having? My GPS won't work after trying a ROM with safestrap. What I've posted here is a result of trying to fix it. I consistently show NO satellites. I consulted the local phone fixers to no avail. I was wondering if it could be related to a modem issue? I think the ROM I first tried did something deep to my phone, though Phone Info showed at the time everything to be original concerning baseband etc.. And a factory reset didn't help.
I'm at the point now of thinking its hardware rather than software but the coincidence to trying the ROM was too high.

Hey everyone!
I am working with this phone and am trying to get a backup modem, can you please ,make a suggestion?
Also are there any ROMs that allow easy access to umts menu through servicemenu? I know the base firmware cripples this and I'm trying to get a work around!
thanks in advanced!
