I'm desperate and can not do, my iphone 5 16gb 5 days ago from constantly restarts, the first day I take a great disappointment to see that the screen was completely blue and turn off a few seconds, and up to two hours later I could not turn it on. during these days is gone restarting me 20 times a day, this time was coming down as to decode something, of many colors, and within seconds turned off, since I have no time for iTunes to recognize it and put it in DFU mode not know what else to do, what ever happened I restarted by pressing power and home, but nothing, no way, soon happens again. I hope you can help me, thanks
