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:

Download this, unzip, and run the .BAT file while the Captivate is plugged into the computer, Debugging enabled

from:
[PROGRAM]One Click Unlock / All Models (Mac & PC) - xda-developers


This harder way also confirmed to work:

Code: 
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>

do that to your rooted phone in ADB
Then just open the file with a hex editor, and SHAZAM! your code is there, 
Around line 515040

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

I did the following:
Code: 
You must be rooted Here's how to grab your unlock code off your own phone, for free!

Connect your phone via USB and open an adb shell (you need the SDK installed)

My SDK is installed in C:\Android

cd c:\android\tools
adb shell
Now that you're in shell type in the following

su
dd if=/dev/block/bml3 of=/sdcard/bml3.bak
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



SSNV.
 
can anyone post screenshots of this working?
and its a true unlock? no issues with 3G, missed calls, etc??
 
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.
 
I follow but no such file or directory.. I also did root explorer and didn't see bm13

Nevermind. Misread BML3 and I read as bm13
 
I got everything but how to read the unlock code from Hexworkshop? Where is it? I open with ANSII where?????
 
Hi! everyone,

I'm new to Android so can you please provide or guide me to a post where is there is a detail guide of how to unlock my captivate?

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