[Nature666]

Hello guys..
My Samsung Galaxy note 2 N7100 is rooted. It shows root access privilege but, my super su requests for update.. i can't use game killer or gamecih, it says "it needs root access". I have CMW installed.
Please any help to get super su working fully will be appreciated. Thanks alot for your time.

You need to download SuperSU binary from the developer website and install it manually.
