You don't need to root it, but if you want to root it anyway I suggest flashing root66 firmware.. Unlock thread is in general, you will need to downgrade to 4.1.1 LJA firmware for it to work.. You can also just flash the LJA baseband in custom recovery and then continue with unlock procedure.. Up to you

Rooting is no problem.. And yes you can flash the LJA firmware in that thread, or flash LJA modem with custom recovery
