EZ- unlock is for the T999 it is what bricked your phone. Our bootloader is unlocked up to the 4.3 MJB bootloader. As long as your phone has never been on the MJB bootloaders go to www.sammobile.com
and go to the firmware tab in the search box enter "i747" Then find the rom you want download it, insert your debrick card get into odin/download mode and flash your heart out.
Use the stickies guide for rooting your phone cf autoroot works well before 4.3, do not flash anything if you're unsure if it is for your phone, ask if it supports your model. Not all galaxy s3's are created equal.
