I'm trying to get my phone back to stock, I ran Odin and selected the tar.md5 file, let Odin do its thing and the phone rebooted when Odin was done ( no errors ) and it's just stuck on the boot animation now. I went back into download mode again to flash the SGH-T989-Stock-UVKID.tar kernel thinking that's why it wasn't booting, but it's still not booting after that either..
I'm coming from Eugenes CM7 if that matters...
Got it working now. Incase anyone ever has the same problem, I had to go into recovery and format/wipe the system.
