Scratch my previous reply.
I now have full root on this phone.
I ended up copying the Superuser.apk from This .zip file
and putting it on the root portion of my sdcard.
Then I used "My Files" in my app drawer to browse for the superuser.apk i placed on earlier and installed it. Do the all option.
After that has completed, I got the message that SuperSU detected Knox and removed it successfully.
Now Titanium backup works great now and no longer hangs on Asking for root rights.
