How can I activate an iPhone locked with Apple ID/Activation Lock?

  In the last few days I have seen the question more and more often in the comments How can I activate an iPhone locked with Apple ID/Activation Lock? and through this article I will try to answer all those who have not yet found an answer. Activation Lock is a system implemented by the company in iOS 7, he working in tandem with Find My iPhone and being thought to reduce the number of thefts of iDevices. Activation Lock- is activated through the application/website Find My iPhone and it allows blocking a terminal iPhone/iPad/iPod Touch and obliging the person who owns it to enter Apple ID- with which the blocking was done to be able to activate it in case of a restore, or to unlock it and use it.

  In case of theft, a thief can do absolutely nothing with the terminal without knowing Apple IDand the password with which the terminal was blocked, a restore, including from DFU Mode, being useless. No matter what you try to do to a terminal blocked in this way, for now there is no hack by which you can remove the protection system implemented by the Apple company and the chances that an Apple Store will help you are small. Considering that the entire system is designed to prevent theft, the only solution is to return a found iPhone, or give up a stolen one, a legitimate user being able to use the methods provided by Apple to activate the terminal with his Apple ID.

  Considering the above, if in the next period you intend to purchase a second-hand terminal, make sure that it is active and works without problems, because if you purchase a stolen and blocked one, you will not be able to use it. The worst part is that stolen terminals locked in this way can be located by Apple when they try to activate, so if the real owner asks the company to monitor it, you may find yourself at some point with the police at door, even if you are a buyer in good faith.
