How To: Unlock Samsung Galaxy S3 with Voodoo SIM Unlock for i9300 GS3

Working Voodoo SIM Unlock for i9300 GS3

  The app is an implementation of XDA Forum Member txlibre‘s procedure for SIM-unlocking the SGS3, which itself comes from Forum Member dagentooboy‘s thread on how to unlock all SGS models via nvdata.bin.
  Voodoo Galaxy III Sim Unlock is written entirely in Java, which means there is no busybox requirement for this application.
 The application requires root in order to modify the /efs/nv_data.bin, and sets the simlock bit from a 1 to a zero.
  At this point, a reboot would be required.
  However using strictly Java, the application parses the /proc folder in order to locate the rild process which triggers the nv_data parsing again.
 This fails verifying the md5, which generates a log file, which contains the newly expected MD5 sum for the nv_data.
  The system-generated MD5 is inserted in place of the original MD5.  It’s an interesting technique, and all this is done with just one click!

Now for the actual process:

1.Root process:

-First download and unzip the following two files:

-Open the Odin .exe file.

-Turn your phone off.

-Hold volume down, home and power buttons and it will boot into download mode.

-Plug phone into computer.

-Press "PDA" in Odin and choose the CF-Root-SGS3-v6.4.tar file you extracted earlier.

-Make sure the "Repartition" box is UNTICKED.

-Press "Start" and wait for the process to complete. When it's done it'll reboot.
 

2.Unlock process:

-On your phone go to Settings > Applications, and make sure "Unknown Sources" is ticked.

-Instal  VoodooGalaxySIIISimUnlock.apk

-Let the app install.

-Now launch the app and choose "Unlock". Your phone will now unlock itself. Reboot and your phone is unlocked!
