People actually trust you with their $700 dollar phones? Why would you root the phone. Just downgrade the modem to any i337 4.2.2 modem and use z3x version 16.9. After operation flash original modem back. I mean this is basic knowledge. G0D forbid you have to learn how to extract a modem from a rom using linux...LoL

I check this method If I337 NB1 version need downgrade.
NB1►DOWNGRADE
1. PIT file 2. Firmware MK2 3. ODIN

1. Download all three files above
2. Open ODIN3v3.09
3. Load both Pit and AP together to corerct slot ( Pit >>PIT SLOT.....AP>>PDA SLOT ) and hit start.....
5. When is done....reboot to stock recovery and choose Full Wipe/Factory Reset.
6. Root using Saferoot Method

When do unlock with checked new security.
