No root access after running Motochopper

view story

http://forums.androidcentral.com – It looks like it worked properly based on the youtube video I saw - there were no failure complaints by motochopper. I installed the drivers on my computer, verified normal access to the S4. I set the phone to developer mode and turned on developer options, and turned on USB Debugging. Motochopper completed and rebooted the phone. I started titanium backup and it says it can't get root access. I don't get what I'm doing wrong. Also, information on finding and installing a ROM is all over the place. Not much in the way of step by step that I can find. Am I looking in the wrong place o (HowTos)
