[Q] AT&T SGH-I747 Soft Brick Need Help!!!
I need help recovering my GS3, i tried using CF auto root to root my phone and i guess it didnt work because my phone doesnt boot past the samsung screen. I didnt have any custom recovery installed so i dont believe and thing was backed up. I am able to get into download mode and recovery mode. I tried flashing stock firmware using kies but it encounters a error saying its a problem with my phone, I tried using odin but it also gives me an error when flashing firmware saying
