So after receiving the update today, I decided to root using the razr blade utility. But it didn't work. I have a superSU app installed that will open but says "there is no su binary installed, and superSU cannot install it. This is a problem!" and then it closes. I can't delete the superSU app. Also i downloaded root checker and i do not have root. Does anyone have any ideas? Is it safe to try again with the superSU app already installed?
