hi guys.i pressed the hold button(one near the camera)and slided the slide key lock.then it stood still and nothing moved from that screensaver picture.then i searched for the way to fix it and reseted it by pressing the 2 buttons at the same time.then apple logo came in,and dissapeared.and dissapears and shows up again,and again.i cant do anything now,and my computer doesnt respond to it when i plug the ipad in.what should i do now?
