Noob question: Reinstalling Rom using ODIN?

So, I'm not really a Noob, just really out of practice and trying to install a custom ROM on my wife's Sprint s5 sm-g900p.

Here's what happened:
1) I rooted the phone
2) Installed TWRP
3) Made sure everything worked fine
4) Downloaded a custom ROM and placed on the External SD Card
5) Booted into TWRP and did an advanced Wipe
6) Made the Noob mistake of also wiping the External SD Card (oops)

So...
7) I downloaded [ROM][ODIN]SM-G900P NE5 (NE5 Modem/Kernel/Bootloader/ROM - Full Restore - Unrooted) from here: http://forum.xda-developers.com/spri...ernel-t2805319

8) I followed the instructions and began the firmware re-installation after pulling the battery for 10 seconds and booting into Download mode..

9) Odin response: FAIL!

Question:
Anyone have any idea how I can put another ROM on this phone to make it usable again?

Thanks
