hey guys, i tried this method on i317m from rogers,
'Note: your phone must be running at least Jelly Bean 4.1.1 (if 4.1.1 does not work, try 4.1.0) otherwise some of the menu choices are not present
Just dial the following keys *#197328640#
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone... enjoy!!! There is no confirmation on the phone that the unlock was successfull.... just reboot your phone....
To test, just insert a sim card from a different carrier/provider. If the new sim card works then your phone is now unlocked.
I have done this to my other Note 2 N7105 originally locked to Orange.....'
the problem is when i press menu and go back one step, there isnt any option 4 for me to press, how can i solve it? i tried couple times, its from rogers... thx in advance!
Only works in 4.1.1 not 4.1.2. You will need to downgrade or flash the 4.1.1 radio.

I have this phone I want to unlock for my carrier (T-Mobile)
AT&T gave me an unlock code that did not work. We tried it more than 5 times and AT&T says that it is permanently locked to AT&T.
Is there a way that I can get this phone unlocked?
Thanks.
give this a shot

It doesn't work on 4.1.2. Make a backup, then use Odin to go back to 4.1.1, then unlock using this method, then upgrade back to 4.1.2 and/or restore backup if you wish.

I have finally come to that decision through my research. My issue now is finding the right version of Odin (I think 3.07 is the latest) and the correct version of 4.1.1 for my phone.
yes is very nice solution
unlock4life
Worked perfectly. Stock Bell SGS3.
Now, it wasn't stock to begin with - I was running Task650's AOKP on it. Of course the instructions didn't work on that so I flashed a stock Bell ROM onto it then it worked perfectly. Phone unlocked on the first try.
Some of the menu items weren't exactly in the same place but they had the same names so no problems finding them.
Thanks!

Do not attempt this downgrade if you have upgraded to the official 4.3 ota. It will brick your phone.

Once done you can upgrade to any firmware you want as it is a permanent unlock. Also if you downgrade from 4.3 i dont see why it would brick, but if the admin says so then i believe it.
You should probably put a large RED warning in the first post that if they down grade from 4.3 to 4.1.1 to unlock they will hard brick. Specifically flashing the 4.1.X bootloaders cause the brick.
also on 4.3 this appears to work and retains sim unlock SHA256 OFF

Downgrading from 4.3 is guaranteed to hard brick the phone. As Mr. X says please make note with giant warning at beginning of first post. This will break phones and people need to know.

I did mine a long time ago. After reading quite a bit you may be right for the time being. The best I have found without a risk of a brick is this:
There is a lot of confusion about unlocking in this thread and elsewhere. Your S3 can still be unlocked after the 4.3 update, just keep in mind that most threads either have inaccurate information or miss essential steps.
Unlock codes and procedures often change or play musical chairs in major software updates. Prior to the problematic 4.3 update you could unlock your S3 with the cited procedure in this thread. This is a permanent unlock and would survive firmware changes. This only applies to touchwiz ROMs e.g. North American factory ROMs or custom ROMs that preserve the dialer codes. This unlocking procedure is also distinct from the carrier specific unlock codes or commercial unlockers who either have access to the official database or have figured out the key algorithm.
If your phone has not taken the 4.3 update yet:
Install the 4.1.1 stock touchwiz ROM and use this procedure to unlock. You can then revert back to your favourite firmware version after your phone has been unlocked.
Dial the following code on the phone keypad: *#197328640#
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF
After choosing this option, wait 30 seconds, then go back one step by pressing the Menu button then select back
Now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALIZE
You should see a message that says
SHA256_ENABLED_FLAG[0]
SHA256_OFF => Not Change
Choose [1] SHA256_ENABLED_FLAG
Wait 30 seconds, then press Menu > Back. Do not use the back key, choose back from the menu popup.
You should now see a message that says
MENU NOT EXIST
PRESS BACK KEY
Current Command is 118640 (if you don't see this message.. skip to alternate step below)
Note that the exact Command number may vary.. don't worry about that.
Wait another 30 seconds, then press Menu > Back. Do not use the back key, choose back from the menu popup
You should see a message that PERSO_NV_INIT is processing, then PERSO_NV_INIT is SUCCESSFUL
Now return to the SHA256 menu and turn Perso SHA256 back on
Back our of all menus and enjoy your unlocked S3
Alternate step. If you didn't receive the MENU NOT EXIST message, then use the back option in the menu popup until you see a menu what includes [6] Common.
Click on [6] Common and choose [6] NV REBUILD
You should now see a message that says:
Golden-Backup exist
You can Restore Cal/NV
Choose [4] Restore Backup
Your phone may freeze or change screens briefly, then should reboot
If you run into errors, look at this link for advice on how to proceed: How to unlock.. (techbeasts.com)
Enjoy your unlocked S3
If you have the 4.3 update:
Now you know that updates are evil or at least mess up your plans.
The unlock procedures have changed somewhat now and it seems that there are now several alternate procedures depending on your carrier.
Gambit #1
If you tried the above and got half way to find that menu item [4] NW Lock NV Data INITIALIZE was missing, then try the following. Note that menu item [4] may also be missing if your phone is already unlocked. So you might want to try a SIM from another carrier to confirm whether your phone really needs to be unlocked.
Dial the following code on the phone keypad: *#197328640#
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF
After choosing this option, wait 30 seconds, then go back one step by pressing the Menu button then select back
Now you are in [6] Network Lock and presumably you now find that there is no [4] NW Lock NV Data INITIALIZE menu item
If so, then press Menu > Back. Do not use the back key, choose back from the menu popup.
Now this is the step that most threads miss, tap on SHA256_ENABLED_FLAG.
This item may look like a message rather than a menu choice i.e. may not be enumerated. Tap it anyway
Now you may see one of several things.
If it appears that you are back to the starting menu, choose [1} UMTS again and follow the original steps and you should find that the missing menu item is now present, although it may be labeled NW Lock NV Data INITIALIZE or NV REBUILD. Or you may find yourself on a page that already has the initialize or rebuild option.
In either case, choose INTIALIZE or REBUILD, followed by the remaining steps as originally described.
If you get a message asking you to reboot your phone to finish, then do that instead of the remaining steps.
I'd recommend that after you are done that you return to the service menu again and ensure that SHA256 was re-enabled. The SHA256_ENABLED_FLAG should = 1 (not 0). If the flag status is 0, then choose the Perso SHA256 ON option.
Enjoy your unlocked S3
Gambit #2
If the above does is still missing key menu items on your phone, then try this alternate dialer code:
*#27663368378#
And then proceed as before.
However, if you encounter the following message:
Golden-Backup exist
Then follow the procedure in this link instead: How to unlock.. (techbeasts.com)
Enjoy your unlocked S3
Gambit #3
If you still have a stubborn phone, try the following dialer code
*#0011#
This will look like an informational screen with no menu choices.
Don't fear, the menu you want is just hidden. Continue with the steps in this link: How to unlock.. (unlockfaq.com)
Enjoy your unlocked S3
Oh no.. that didn't work either!
If all else fails, contact your provider and tell them that you will be traveling in elsewhere e.g. Europe and need to have your phone unlocked. Most carriers will provide you with a network (carrier) unlock code in this situation. Typically without charge, but it will vary by carrier. Or you can avail yourself of a commercial unlocking service. Google will find a googol [sic] of them for you.
Note that you need to insert a valid, non-blacklisted SIM from another carrier to be prompted to enter a network unlock code. It need not be active, just not blocked i.e. reported as lost /stolen. If you have any difficulties entering the code, have a look at this link.
Good luck

Note that the exact Command number may vary.. don't worry about that.
Wait another 30 seconds, then press Menu > Back. Do not use the back key, choose back from the menu popup
You should see a message that PERSO_NV_INIT is processing, then PERSO_NV_INIT is SUCCESSFUL
Now return to the SHA256 menu and turn Perso SHA256 back on
Back our of all menus and enjoy your unlocked S3
Alternate step. If you didn't receive the MENU NOT EXIST message, then use the back option in the menu popup until you see a menu what includes [6] Common.
Click on [6] Common and choose [6] NV REBUILD
You should now see a message that says:
Golden-Backup exist
You can Restore Cal/NV
Choose [4] Restore Backup
Your phone may freeze or change screens briefly, then should reboot
If you run into errors, look at this link for advice on how to proceed: How to unlock.. (techbeasts.com)
Enjoy your unlocked S3
If you have the 4.3 update:
Now you know that updates are evil or at least mess up your plans.
The unlock procedures have changed somewhat now and it seems that there are now several alternate procedures depending on your carrier.
Gambit #1
If you tried the above and got half way to find that menu item [4] NW Lock NV Data INITIALIZE was missing, then try the following. Note that menu item [4] may also be missing if your phone is already unlocked. So you might want to try a SIM from another carrier to confirm whether your phone really needs to be unlocked.
Dial the following code on the phone keypad: *#197328640#
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF
After choosing this option, wait 30 seconds, then go back one step by pressing the Menu button then select back
Now you are in [6] Network Lock and presumably you now find that there is no [4] NW Lock NV Data INITIALIZE menu item
If so, then press Menu > Back. Do not use the back key, choose back from the menu popup.
Now this is the step that most threads miss, tap on SHA256_ENABLED_FLAG.
This item may look like a message rather than a menu choice i.e. may not be enumerated. Tap it anyway
Now you may see one of several things.
If it appears that you are back to the starting menu, choose [1} UMTS again and follow the original steps and you should find that the missing menu item is now present, although it may be labeled NW Lock NV Data INITIALIZE or NV REBUILD. Or you may find yourself on a page that already has the initialize or rebuild option.
In either case, choose INTIALIZE or REBUILD, followed by the remaining steps as originally described.
If you get a message asking you to reboot your phone to finish, then do that instead of the remaining steps.
I'd recommend that after you are done that you return to the service menu again and ensure that SHA256 was re-enabled. The SHA256_ENABLED_FLAG should = 1 (not 0). If the flag status is 0, then choose the Perso SHA256 ON option.
Enjoy your unlocked S3
Gambit #2
If the above does is still missing key menu items on your phone, then try this alternate dialer code:
*#27663368378#
And then proceed as before.
However, if you encounter the following message:
Golden-Backup exist
Then follow the procedure in this link instead: How to unlock.. (techbeasts.com)
Enjoy your unlocked S3
Gambit #3
If you still have a stubborn phone, try the following dialer code
*#0011#
This will look like an informational screen with no menu choices.
Don't fear, the menu you want is just hidden. Continue with the steps in this link: How to unlock.. (unlockfaq.com)
Enjoy your unlocked S3
Oh no.. that didn't work either!
If all else fails, contact your provider and tell them that you will be traveling in elsewhere e.g. Europe and need to have your phone unlocked. Most carriers will provide you with a network (carrier) unlock code in this situation. Typically without charge, but it will vary by carrier. Or you can avail yourself of a commercial unlocking service. Google will find a googol [sic] of them for you.
Note that you need to insert a valid, non-blacklisted SIM from another carrier to be prompted to enter a network unlock code. It need not be active, just not blocked i.e. reported as lost /stolen. If you have any difficulties entering the code, have a look at this link.
Good luck

Thank you,Tried all those and non work i found this site where they charge me $6 hopefully its true
Did you by chance call AT&T and ask for it? I have had better luck with them than big red. If you have an account in good standing anyway.

I would like to know the cheapest place as well...
I tried to unlock it based on above (I am on 4.3) and no go.
I know the bootloader is locked in 4.3 but is the modem? maybe you could downgrade to the 4.1.1 modem and then unlock and reflash your 4.3?

I didn't know this. I saw several posts from XDA members that were on 4.3 and wanted to unlock their phone for free. If they can just flash the modem, unlock, and reflash the modem, that would be pretty simple.

indeed we just need a brave user to try it risking his phone's life. or someone more knowledgeable than me that already knows the answer.

Do you know anyone that has actually gone through the process of unlocking by installing the 4.1.1 modem?
I saw a post about someone doing this with a 4.1.2 rom but not a 4.3 ROM.

In another thread, an XDA member had a stock 4.1.1 ROM (modem too) running on a 4.3 bootloader and the required menu options for unlocking the phone were not present which leads me to conclude that you need to be completely stock 4.1.1, including the bootloader.
when updating past 4.3 you aquire the updated bootloader and can no longer "safely" downgrade to 4.1.1 to unlock this phone. however if you:
1) Root the phone and allow SU to disable knox
2) Install custom recovery (TWRP, CWM, OR OTHER)
3) Boot into recovery and flash the atti317ucalj2modemfixed.zip modem
4) After reboot you can use this method to unlock:

Just dial the following keys *#197328640#

5) Reboot recovery and flash the newest modem I317_ucucne5_modem.zip
6) Reboot again and enjoy your fully unlocked 4.4 note 2 att with out losing your data or bricking your phone

With all due respect to OP and his lack of posts (like I have room to talk, right? ) can anyone else verify this as working before I attempt this? I need to unlock my phone and would rather do this than flash 4.1.1 (and trip Knox) and then reflash to a 4.4.2 ROM.

i hope others will try this and post their progress, but just as a personal reference in my repair/modification store i have now successfully unlocked 16 note 2's that i have bought and customer's phones. hope this information helps.
The information helped a lot when the other guy figured it out and posted it a year ago.
ok that didnt work for me i get an error, nothing happens til I hit send on the dialpad, then I get this connection problem or invalid MMI code

the other posted method works for previous software, the method has to be tweaked to work on 4.1.2 and above. im guessing people arn't reading that part of the post just assuming this is the same unlock method that use to work with out flashing the modem. they removed the #4 prompt in network lock on the newer modems so you cant manually unlock them.

send me your model, current version, baseband etc and i will help you figure it out. you shouldn't hit send in the dialpad to access the hidden menus. apon hitting the last # it directly loads the hidden menu.
I'm running an AT&T Note 2 (SGH-I317) running Ditto Rom 3 v2, baseband I317ucucne5
Hi I bought an att note 2 with 4.4.2 will this method work.
baseband
i317ucucnj1
kernel
3.0.31-1728680
build
kot49h.i317ucucnj1
works
I just tried this on my note 2 with 4.4.2 and it worked perfectly. Thank you.
Would this work on an Canadian sgh-i317m?
I am going to try this on my i317m (Koodo) Dn3 Rom, will post results soon
Edit:
Didn't work, when I put numbers on dialpad, it doesn't go right away, I then press the call button and it says "Mobile network not available"
Should I try going back to Stock Rom, then trying it? Will it stay Unlocked if I restore a previous EFS?
Edit2:
Went back to stock 4.4.2 Koodo, and did the following, but when I put numbers on dialpad, it goes through but everything is blank, like there is no menu to choose from
Did you downgrade the modem/baseband first before using the dial pad? This menu is only accessible in the older one. Also I'm not sure of the compatibility of the modem with a phone other than the I317 att. Other variants probably have a different modem and you'll have to find an older version of yours to flash then flash back to current.

Yes, I downgraded to the one you have provided, and surprisingly it was not accessible, but on my stock modem, the menu is accessible but doesn't work.
That was also my thought, time to modem hunt!
