Note 4 Marshmellow root not working!

So usually I don't have any issues with rooting my phone and all. For some unknown reason i just cant seem to root my Sprint Note 4 phone!

Information:

Phone: Sprint Note 4
Model: SM-N910P
Android Version: 6.0.1
Software Version: N910PVPU4DPE1
Build Number: MMB29M.N910PVPU4DPE1

TWRP Version: twrp-3.0.2-0-tbltespr (Which i successfully managed to install)

I used CF-Auto-Root-trltespr-trltespr-smn910p.tar

I did notice that when i flash my auto-root it says "Finding boot image.....Boot image not found, Aborting" under the Boot image patch.
Any ideas on what it means? I'm at a total loss so anything would help me at this point.
