  1. Hi i was checking your guide and compared it to my phones build nr i have Jzo54k.i9300xxema2 in the europe version but in the guid it says europe should have an i in the begining insted of the J, cant i root with this then?? sorry if stupid question but iam a noob 🙂

    1. Build number doesn’t matter, the software version does i.e 4.0.4 ICS or 4.1.1, 4.1.2 JB. Some root method that works on Ice Cream Sandwich will not work on Jelly Bean. Anyway, forget about a NOOB thing, if you want to learn something keep on asking.
