Hi, I'm new incase you haven't guessed.. I downloaded this program called Catepillar from Installer, and I went to change one of the settings and it required me to restart. After I restarted, It got stuck on the Apple loading screen with the Loading circle going round. Every few seconds it'll play the Connection Sound. I have tried holding On/Off and Home button in at same time and it didn't work. I also tried draining the battery and that didn't work. Help please?
