[Q] N910F rooting/room issues topic

Sooo, I'm new to rooting a note 4. I have the the international version, rooting is no issue now... I can do that quite quickly.
My issue is flashing a new from via TWRP. No matter what I do it fails everything, last night I managed to load CM12 but it just stayed in a bootloop for over 30minutes. I just restored it to factory. I thought maybe I'm not destined to have cyanageonmod :(

Anyways I found another decent room called Beanstalk, it seems like a pretty solid room (thoughts?) but when I go to flash the zip file it just says it can't mouth the file from what ever drive.

What am I doing wrong? I wiping the four things I'm meant to delete before I flash and still nothing

My phone: N910F running on 5.0.1
Baseband:n910fxxuibob4

Ive looked at ever forum possible but can't see what's wrong? I've also tried 3 different versions of Cm12 from different developers that are meant to work...

So again where am I going wrong?

If this is in the wrong place I am sorry! Could I be pointed in the right direction :)
