"There is no SU binary installed and SuperSU cannot install it"
I used CFRoot and Odin to root my Galaxy S3 i9300. It seemed to go OK but when I open SuperSU it says "There is no SU binary installed and SuperSU cannot install it. This is a problem!" I have tried to install SuperUser but that also says the SU binary isn't installed.
What has gone wrong? Do I need to run the Odin process again?
