it was in the above how to..
"Move the supersu zip onto your internal sdcard. It can be downloaded here:
You can use Superuser as well. Its your preference, but this guide uses SuperSU.
Uninstall weaksauce. It's no longer needed.
Uninstall SuperSU. It will be reinstalled when you flash the supersu zip. If you have SuperSU Pro installed, you can leave that in place, as that app only holds a key.
From adb, type:
adb reboot bootloader
Flash a custom recovery. Currently, only CWM recovery is available. Follow the directions here:
Reboot into Recovery
Flash the supersu zip you downloaded.
Reboot and you're done. You have s-off and permanent root.
You can delete the downloaded supersu zip off your internal sdcard; its not longer needed."
