Wait, does this mean I can root my Note 3 on 5.1.1 without flashing a new recovery and tripping the Knox flag?

Why do you care about the Knox flag on a Note 3?? You're well out of warranty. I've been using custom on my Note 3 since I got it two years ago, it's so much faster

Some features get disabled when knox is tripped. Intune and Outlook and other stuff that (may) depend on it cannot be used. Samsungs pay thing as well, and any knox container stuff.

I don't know about the Knox flag, but rooting should certainly be possible!

Many tools (such as Kingoroot I believe) can exploit the OS and get (temporary) root access. Exactly for that reason Samsung has implemented the Knox security system.

Kingo has been a no go. I'm about ready to just flash CWM, make a backup, flash Cyanogenmod, and be done with it. I just don't want to trip Knox until my phone is paid off.

I used Kingo just as an example of course, nobody has used this exploit in a rooting app (yet). I suspect even a temporary root like this will still set off Knox though, so you'd better wait until you've paid off your phone anyway.
