You should really search before making a thread like this. And I know you'll say I did search... But apparently not hard enough

Sorry I didn't search, I should search in the future before posting something. But I also wanted to show a video tutorial of the unlocking. Thanks.

Hi,
Is there a way to check if this works without another sim card??
Any codes to see if it's unlocked???

I did this y'day. Tested today with my colleagues T-Mobile sim. It connected to T-Mobile network without any hassle. It was missing proper APN so it connected to edge only.

Tried the same on my wife's rooted stock (4.0.4), and it didn't work.

So like the original post (not OP) states, you have to be on 4.1.1.

The point of these threads is to unlock for free.. We know you can pay 10-30$ in other places, if we were interested in that these post would be useless..... You can even unlock for free by calling your carrier. No need to pay ;)

Yeah but did you see who I quoted?? ;)
They said to pay 10-20$ to get it unlocked. And that's why I said if we were trying to pay for unlock there is no reason to have these threads... Catch my drift?
Lol my point is that yes these threads are useful, we don't want to pay to unlock our phones :D

Is there a way to undo this? It seems as if my phone is stuck in debugging mode.


Hey not trying to be an a hole but this method has caused me LOTS of friggin problems. Yes it unlocks but it is only temporary. A couple of phone calls or an hour later or so and the phone loses service.

I've tried to do it all kinds of varations of this and same result.

Also tried to do a factory reset and whatever this screws with survives that too.
I broke down and bought an unlock code but now I can't get the phone to prompt for it.
Is there a way to undo this? Already tried go turning the flag on and initializing.

I'm assuming the software allows you to unlock like this for debugging but then goes back for security.

I have an S3 with 4.1.1 that was made for T mobile.


Again I have an unlock code just need a way to put it in.

You can't undo this.
And you'll never lose unlock after you have unlocked.
It is not temporary.

You bought an extra unlock code for nothing.
This will not mess with anything on your phone unless you pushed something you shouldn't have.

Also if you're running a custom rom/kernel/modem check in to that.

You also started 3 different threads with the same exact question.
Stick to one thread.

    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

    Hi,

    Does anyone have a method to make this work on Galaxy S3 running Jelly Bean 4.1.2? I want to get my phone unlocked but dont really prefer to downgrade to 4.1.1 because of the features 4.1.2 has.

    Any other way?

    Thank You ! :) Reply ASAP.

    You could backup your rom, flash the stock 4.1.1 rom, unlock, restore your 4.1.2 backup.

    If you follow this to the end then you are all good.....make sure you get the 118640 code... if you get 118630, you have probably locked it again....

    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 .....

    u should see SHA256_ENABLE_FLAG[0] SHA256_OFF NOT CHANGE, touch SHA256_ENABLE_FLAG[0] and wait

    After last step (touch SHA256_ENABLE_FLAG[0] to get:

    MENU NOT EXIST
    PRESS BACK KEY
    Current Command is 118640    ...wait...

    press (Menu -> Back)

    PERSO_NV_INIT is processing

    then

    PERSO_NV_INIT is SUCCESSFUL
