Well this is the method I used to unlock my S3 movistar.
requirement:
1 - Have the S3 root
2 - Make a copy of the EFS folder
3 - Hex Editor (I used Notepad + + with the plunging HEX)
4 - Have installed root explorer
We begin:
1 - We copy our EFS folder to your PC and perform a second copy to work with.
2 - Open the file nv_data.bin with Hex editor
3 - We go to the address 00181460 and modify 01 to 00
4 - Save the file

http://forum.xda-developers.com/attachment.php?attachmentid=1135934&stc=1&thumb=1&d=1339936756

5 - copy the file to your S3.
6 - With the Root explorer, activate R / W in the EFS folder and file replace nv_data.bin.
7 - With the root file explorer to give the following permissions:
a. Owner: Read, Write, Execute
b. Changes owner and group: 1001-Radio
8 - Restart the phone.
9 - After restarting check by dialing * # 7465625 # to the continuous network lock ON
10 - Now we copy the file nv.log of your S3 (located in EFS folder)
11 - Open this file and we will eventually see something like this:
Fri June 15 16:39:51 2012: MD5 fail. md5 orignal fd4425f64f7f498230f16cd2234638a '2 '
computed md5' faf1572f4a4dd15f1f9061840cc4b42f '(Rild)
Fri June 15 16:39:51 2012: restored backup NV.

12 - Now we're working copy of our EFS folder
13 - Edit the file nv_data.bin.md5 and see at the dump that matches the first line: 2fd4425f64f7f498230f16cd2234638a
14 - Modify from the dump placing the data in the second line: faf1572f4a4dd15f1f9061840cc4b42f
15 - Save the file.
16 - repeat the 5-6-7-8 but with both files (nv_data.bin and nv_data.bin.md5)
To XXBLG1 add this step:
17 - We copy and rename nv_data.bin and nv_data.bin.md5 to nv_data.bak and nv_data.bak.md5 respectively.
18 - After rebooting check by dialing * # 7465625 # to the continuous network lock OFF
I hope you find it helpful, as always, you are solely responsible, I just indicated to you those steps I've done on my terminal.

This method is based on dagentooboy work http://forum.xda-developers.com/showthread.php?t=761045 so I must thank you for your work and the people he thanked.

Hi, I need to get my phone unlocked quick :)
I have used mskip's TooKit to backup my EFS folder.
It has given me two files: efs.img (20,480 KB) and efs.tar(2 KB)

How do I get the 'nv_data.bin' from 'efs.img'
I am searching the net as well, but for quickness I have asked the question :)

EDIT:
OK, I found nv_data.bin in the /efs folder :)

---------- Post added at 11:20 PM ---------- Previous post was at 10:54 PM ----------

Ok, im stuck at step 11:
11 - Open this file and we will eventually see something like this:
Fri June 15 16:39:51 2012: MD5 fail. md5 orignal fd4425f64f7f498230f16cd2234638a '2 '
computed md5' faf1572f4a4dd15f1f9061840cc4b42f '(Rild)
Fri June 15 16:39:51 2012: restored backup NV.

I cannot find this text in my nv.log file
EDIT:
OK, so for some reason I didnt copy the modified nv_data.bin back to my phone... oops!

Those programs make a bit by bit back up of the entire partition, which includes the EFS folder I believe, which is the way to go. I messed up my vibrant once somehow because that partition got corrupted, which disallows writing to the partition, meaning you can't copy over the /EFS stuff. Before doing this, make sure you have a backup! When you punch in *#06# after doing it, and it should still show your IMEI number and not the generic Samsung number. I think it caused some issues w/ the market as well.

In any case, I knew a sim unlock would be out soon. I think ALL Samsung phones have been unlocked similarly since the galaxy series. I'll make sure to try this once I get my phone this Thursday. Maybe someone will make an APK soon.

Your problem is the app you used. In the line 00181467 , you must change the 01 to 00.
