i managed to do it , but wifi icon had trouble and coudnt turn it on after rooting , so i tried to look for the stock version rom for that model and i tried to install it via odin .
i falided and now when i whant to start the phone it says firmware upgrade encountered an issue, please select recover mode in Kies & try again.
so i did as i was told to , i connected the phone to my laptop and open Kies but it never ends trying to connect the phone
im desperate i havn´t been able to use my phone in 2 days and it's starting to become an issue
i hope i described my problem the right way
