Bruno ,

Here are the steps how to unlock your S3 (see attached):

1.Root your phone.Backup EFS folder.Note IMEI *#06#_NetworkLock_ON*#7465625#.
2.Extract_nv_data.bin_Original
3.Change_nv_data.bin_replace_and_restartS3
The nv_data.bin owner : radio and rwx rights (700)
4.Copy_MD5value_from_nv_log_afterStep3
5.Change_nv.data.bin.md5_with_value_from_Step4_cop y_restartS3
6.Check_IMEI_and_Network_Lock_should_be_OFF

I'm assuming you know/have already rooted your S3.

If you need help let me know.

Good luck !

Have a nice day !

My phone is rooted, but how to backup efs, extract nv_data.bin and do all others command ?

To backup, you make a copy of all your /efs folder to your SDCard with RootExplorer for example... (Copy/Paste)

I follow your steps but it's not work for me.
I must backup and restore nv_data.bin.

So here are the steps I follow:

1. Root your phone.
2. Backup /efs folder.
3. Change /efs/nv_data.bin rights to rwx rw- rw- (755)
4. Edit original nv_data.bin and replace "01" to "00" in adress 181469 and save
5. Backup your /efs/nv_data.bin in /sdcard
6. Change /efs/nv_data.bin rights to rwx --- --- (700)
7. Reboot your phone.
8. Open /efs/nv.log and search the last line with "MD5 fail" and copy the second md5 checksum
9. Change /efs/nv_data.bin.md5 rights to rwx rw- rw- (755)
10. Edit /efs/nv_data.bin.md5 and replace current checksum by the copied checkum in previous step and save.
11. Change /efs/nv_data.bin.md5 rights to rwx --- --- (700)
12. Delete /efs/nv_data.bin
13. Move /sdcard/nv_data.bin in /efs
14. Change /efs/nv_data.bin rights to rwx --- --- (700)
15. Reboot your phone.
16. Check Network Lock with *#7465625# (should be OFF)
17. Enjoy your new unlocked GS3 !!!!

Notes:

• To backup /efs* I use ES Explorer
• To edit nv_data.bin, I use HexEditor
• There is a new line after checksum in nv_data.bin.md5, I think it's important, but not sure
