Exclamation [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

Are you still able to get it into download mode?

Press and hold volume down + home + power at the same time

If you had the 4.3 bootloader on your phone, you cannot use Odin to flash a stock ROM.

Were you running the stock AT&T 4.3 ROM?

Based on your Odin printout in the first post you were flashing a modified 4.1.1 kernel to install root. This should be fine if you were on either the 4.1.1 or 4.1.2 stock ROM. If you were on the 4.3 stock ROM your root attempt is probably the source of the problem.
IMPORTANT How to proceed from here depends on if you were on 4.3 or an earlier version of stock.

Also, since this forum is for AT&T and Canadian variants; I see the title of the first post says i747 - is this correct? It matters.
