Good news for Samsung Galaxy S users now you can unlock your phone just with your USB cable.When you unlock youe Vibrant,Captivate or Galaxy S you can run a new Sim card and with AT&T SIM you can use 3G data connection with 2Mbps Download.


How To Unlock:


Using ADB

Make sure that Network Lock is the only thing on… go to phone and enter *#7465625#

Make sure USB debugging is enabled (Settings->Applications->Development->USB Debugging)

Step 0.5. – The easy way

Open Terminal and run Generate_Code.sh

Save the code

Jump to step 3.


For Windows (UPDATED Now includes Un-Freeze Code)

Run Generate_Code.bat

Look for the line Network Control Key:YourCode

Save the code

Jump to step 3.

It’s a win32 executable. Run the program from command line with the blockdevice backup as parameter:


c:\sgux.exe bml3.bak


IT returns the unlock code fory your phone.


It’s based on the tip posted on this thread by rhcp0112345.


It’s works with european sgs.


OR

Open the file in a HEX editor

Search for SSNV

At the end of this block of data there should be a string of numbers

(my unlock code started at 0x18005a)

The format will be numbers.unlockcode.numbers


Step 3. – Enter the code

Power down your phone

Put in a SIM card from another carrier

Power up your phone

When it boots up it will ask for the unlock code that you found above


OR if you don’t have another SIM you can try this (NOT TESTED) (Thanks RazvanG)


remove sim card

power on phone without sim

enter *7465625*638*# and relock the phone to another network other than the one u have u’r sim card (eg 22610)

power off phone

insert sim card back

power on and enter nck code extracted from .bak file

phone unlocked


Step 4. – Flash back (IF THE CODE DIDN’T WORK)

Flash back to an older firmware (I9000XXJF7 with 513.pit worked for me)

Now enter the unlock code you generated in Step 2.


Using the Market App

Search for Galaxy S Sim Unlocker in the market. (It is $10 and people say it works)

After you get the NCK code using the method above, enter: *7465625*638*#

There will be a pop-up box.

Complete the first field (MCC/MNC) with the network you want your phone locked to (eg. 226 10 where 226 = romania; 10 = orange etc.) and the second field (Control Key) with the NCK extracted from the .bak file.


Press OK and your phone should relock.
