[q] need help install stock rom

I am not an expert at installing ROMs on Android devices. I hope someone can help.



I have a Sprint Galaxy S4, SPH-L720. I have installed CM12 but now I would like to return to a stock ROM. I downloaded several from Sammobile. Now, I cannot install them.



I have tried several versions of ODIN. Attached is the message I get when trying to flash with ODIN 3.09. I have also tried to install from an SD card using CWM and TWRP with similar failure.



Any help will be greatly appreciated.
