Step 16: After the phone reboots, perform another factory reset, then redownload SuperSU from Play Store and go through the initial set up

Now your Galaxy S4 should be running Samsung's stock Android Lollipop firmware which is rooted, with Knox flasg at 0x0.


Disable the Knox app, which can be done with Titanium Backup by freezing all the Knox-related things or, delete the files manually.

Using a root editor, edit the file/system/build.prop and change the line (This is normally set to= true). This will solve issues related to SELinux.
