How do you take Configuration off your Ipad
My Ipad was Configured by Success Academy when I got it and I tried to take it off so they sent me an email on how to take it off. So I followed the steps and when I restarted my Ipad it said that my Ipad was still configured by Success Academy and when I pressed next it asked me to put in a username and password and I don't know the username and password making me locked out of my ipad. I really need your help because I want to start using my Ipad again.
iPad, iOS 8.4.1
