I got a S4 today and I rooted it, and flashed CWM recovery, backed up the firmware, rebooted and everything was good. I updated the phone an hour so later and the boot hung on yellow Sprint screen. I rebooted into recovery and re-flashed my backup but that didn't fix the device. Now I've been trying to flash back to stock using Odin and this is what I see.

I was on 4.3 when this all started so I am attempting to flash the MK2 file back on my device. I removed the drivers, and re-installed and that made no difference. Any advice would be great.
