    YouTube - How to Unlock Your Samsung Captivate (AT&T) for FREE

    Even easier: Search market for "Captivate Unlocker"and download the free app by gentoo boy
    Easiest way yet:

    This harder way also confirmed to work:

    Code (Text):
    1. cd /dev/block <enter>
    2. su   <enter> <at this point your phone will ask for superuser access ALLOW it
    3. dd if=/dev/block/bml3 of=/sdcard/bml3.bak <enter>
    4.  
    5. do that to your rooted phone in ADB
    6. Then just open the file with a hex editor, and SHAZAM! your code is there,

    Yep it works.
    I used HexWorkshop for windows to find the code

    I did the following:
    Code (Text):
    1. You must be rooted Here's how to grab your unlock code off your own phone, for free!
    2.  
    3. Connect your phone via USB and open an adb shell (you need the SDK installed)
    4.  
    5. My SDK is installed in C:\Android
    6.  
    7. cd c:\android\tools
    8. adb shell
    9. Now that you're in shell type in the following
    10.  
    11. su
    12. dd if=/dev/block/bml3 of=/sdcard/bml3.bak
    13. Mount your SD card on your computer and open bml3.bak in a hex editor. Search for the string SSNV (it's in caps). You'll see something like this
    14.  
    15.  
    16.  
    17. SSNV.

    Worked like a charm! I checked out the thread on HowardForums (which I am a member of as well, so I trust the content) just to make sure I did everything right and it worked! Network Unlock Successful!

    Yes, it is a true network unlock. It would be the same code ATT gives you next year when they start releasing codes.

    Thanks everyone for helping

    I'm just wondering if someone could help me with this, I follow steps listed on this post but got stuck at "c:\sgux.exe bml3.bak" command prompt says C:sgux.exe not found

    can someone helps?





    If you have a rooted phone,

    Now we will work on getting an unlock code for your phone. For this, You will need Command prompt, android SDK, and unlock code finding app. Make sure your device is plugged into your computer.

    1. From Command prompt run the following commands:
    adb shell <enter>
    cd /dev/block <enter>
    su <enter> <at this point your phone will ask for superuser access ALLOW it>
    dd if=/dev/block/bml3 of=/sdcard/bml3.bak <enter>

    This will save a copy of bml3.bak file in your phone. Now you need to copy this file from my files (in phone) to your computer folder containing android sdk. Almost done....
    Now run command prompt again and add these commands exactly..
    c:\sgux.exe bml3.bak

    That command depends on where you have saved all the files. Once done, It will give an 8 digit code which is an unlocking code for your galaxy s. Enjoy...

    Any questions, PM me. This all info was combined from XDA. All credit goes to them..

    Is there some hidden secret menu or alternative way to enter in the unlock without using another sim card? I have trouble finding one at the moment.

    I been looking for the same thing and trust me there's no other way. All the known codes don't work for the Captivate. You could re-lock it to another carrier and then try using the sim card for att. That seems to be even more trouble

    Did you use the One-Click unlocker? [PROGRAM]One Click Unlock / All Models (Mac & PC) - xda-developers

    For some reason I was under the impression that you didn't need root for that method. Or did you use the longer method?

    Anyone know how to change the title of a thread on this forum? This unlock method is now confirmed by a ton of people.
