I could not get Normal or TWRP/CWM installation method to work (I'm on Safestrap). So here are the steps to make it work:
Go to: http://download.chainfire.eu/450/Sup...erSU-v2.00.zip (THIS IS CHAINFIRE'S SITE)
Reboot into Safestrap Recovery
Install the .zip file you downloaded from Chainfire's site.
Open SuperSU....and VOILA it wont ask to update binaries.
I hope this helped anyone having issues updating SuperSU on their newly rooted ATT Note 3 with 4.4
Note I take NO CREDIT for this. I just want to share with the community what I figured out.
