Since the introduction of iOS 5, there has been a very annoying problem that mainly affects owners of iPhone terminals, but also owners of other iDevices. In a completely random way, you may find that your iDevice shuts down out of the blue and of course there is no logical explanation for this kind of "behavior" of our iDevices. It's not the first time I'm discussing this problem, but I've noticed that lately more and more users are facing it and I think it's useful to bring the subject back to your attention.
The problem occurs both for those who have a jailbreak and for those who do not have a jailbreak, so you can be affected no matter how you use your iDevice. Practically, leaving the terminal on the table, you will notice that it closed by itself, although you did not physically do this, and when you connect it to the computer, you will notice that it is recognized by iTunes. Well, basically the device is in DFU Mode for one reason or another and for now there is no logical explanation for this automatic introduction of iDevices into DFU Mode.
If you don't have a jailbreak, the solution is very simple: simultaneously press the Home + Lock buttons and keep them pressed until the apple appears on the screen. If you have a jailbreak, then connect the terminal to the computer and start it tethered with iBooty or redsn0w and everything will return to normal. I hope that everything I wrote here will help you in the future because many people have encountered this problem.
