Issue rooting/Odining certain ROM's

I had been on an NK2 based version of SmoothKat forever and decided it was time to upgrade last night after I had trouble with Xposed Framework. I wiped everything and odined HYBRID_OB7sbl_SPT_N910PVPU4COG5 without any trouble. When I attempted to root with CF-Auto-Root I boot looped the phone. I can Odin HYBRID_OB7sbl_SPT_N910PVPU4COG5 successfully and run it unrooted, but as soon as I attempt to root it, I boot loop the phone again. In addition, I don't seem to be able to Odin stock OB7 or stock NK2. When I attempt to Odin either I get this on Odin:

and get this on the download screen:

I can wipe my phone clean and switch between SmoothKat and HYBRID_OB7sbl_SPT_N910PVPU4COG5 all day. Does anyone know what I've done or how I can fix it? Thanks guys.
