Use odin 1.85, correct usb drivers, uninstall/kill kies. If you can still run a 4.3 rom like you said then obviously your bootloader hasnt been updated. Or 4.3 wouldnt boot at all.
Also you say odin gives you a fail, but you dont even give the details as to what fails? A simple copy and paste is all that is needed.
