Need help. I downloaded Intelliscreen X and it automatically restarted. Goes to apple logo, goes black, and then goes to a dim apple logo and repeats off an on right there. Tried to restore in DFU and Recovery mode, but iTunes says something about the build being invalid or something so I can't restore. This happened earlier when I downloaded Winterboard, but I was able to get back to the homescreen. I can't now, I've done over 2 dozen resets. Of course this has to happen as the last thing I do for the night. What should I do?
