need guide to root and install TWRP on Sprint Note 5 upgraded to Android 7.0

[cynflux]

Hello,
I am looking for a guide to root and install TWRP on Sprint Note 5 upgraded to Android 7.0.

Some background information:

Note 5 was on Android 5.11 and was having random reboots, caused by unstable Noble kernel.
I used the following guide to root, install TWRP and stable Beastmode kernel.

Note 5 went south after i attempted to install Xposed on rooted 5.1.1.
I experienced bootloops and was never able to boot in 5.1.1 ever again.
I failed to flash stock 5.1.1 to Note 5, despite multiple tar's and versions of ODIN.
I though my phone was unrecoverable.
Fast forward 2 days and i was able to successfully flash Android 7.0 via ODIN.
I can successfully boot into Android 7.0, though i prefer to be rooted.

Now i need to root Android 7.0, install TRWP, upgrade to stable kernel, and install Xposed, if possible.
Knox has already been tripped and I was not going to use Samsung Pay anyway.

Phone details:

Model number: SM-N920P
Software version: N920PVPU3DQC5 (Nougat 7.0)
Hardware version: N920P.04
Baseband version: N920PVPU3DQC5
Build Number: NRD90M. N920PVPU3DQC5

Please let me know if more information is needed.

Thank you in advance.
