Disabled phone and say's "connect to iTunes."

Okay but my phone was glitching and i decided to do the good old restart, and when it came back on it said to "connect to iTunes" so I did, but when I did it ended up saying "iTunes could not connect to this iPhone. An unknown error occurred ( 0xE8000015)" please someone help i have not had a phone for four days. ;-; <3
