Carrier Unlock Method for the Galaxy S3 and Galaxy Note 2 Running Jelly Bean, Running in the Wirld

| December 7, 2012 | 10 Replies

    Considering how many Galaxy S3′s and Note 2′s Samsung has sold already, it’s pretty likely that you, or someone you know, has one or the other. And now there is a carrier unlock method out in the wild. This will allow you to unlock your device and run it on another carrier. But this will not work for Galaxy S3′s or Galaxy Note 2′s on Verizon, Sprint or any other CDMA carrier. As those models will only work on that particular carrier. And this unlock is only for GSM carriers (i.e. AT&T, T-Mobile, and others worldwide)

    Now it’s important to let everyone know that we do not support this procedure, so if anything goes wrong it’s on you. Now that you understand that we are not responsible for damage caused to your device, let’s go ahead with the instructions from Redmond Pie on unlocking your device:

    Step 1: On your Galaxy Note II, launch the phone app and press these keys:
    *#197328640#
    Step 2: From the Main Menu, navigate to [1] UMTS > [1]Debug Screen > [8] Phone Control > [6] Network Lock > Options.
    Step 3: In the Options screen, choose [3] Perso SHA256 OFF. Wait for 30 seconds after making this selection.
    Step 4: Go back one step by pressing the menu key, and then back once. You should now again be in [6] Network Lock
    Step 5: Here, now choose [4]NW Lock NV Data INITIALLIZ. Wait for one minute after making the choice.
    Step 6: After a minute has passed, reboot your Galaxy Note II.

    Also, XDA forum member owl74 found out there is a hidden menu in Touchwiz which will allow you to unlock your device from your own home. This method is confirmed working on the GT-N7105, but should work on other Galaxy S3 and Note 2 models. You can find out more information from the source below.

    So who’s ready to take the plunge and unlock their Galaxy S3, or Galaxy Note 2? If you are brave enough to unlock your device, let us know in the comments below how well or not so well it worked for you.

      I've been a huge fan of Android since the OG Motorola Droid hit back in 2009 on Verizon, since then I have gone on to own some of the best devices we've seen including the HTC EVO 4G, Samsung Galaxy Nexus, Nexus 7, Nexus 4 and the Samsung Galaxy S3. I also have a passion for writing about anything having to do with Android.

        Funny. I can get into that menu on a Bell S3. Try cutting/pasting the code.

        What carriers will this work for on a Samsung Galaxy s3, such as Sprint, Verizon, AT&T, etc.?
