With the arrival of the iPhone 7 and iPhone 7 Plus, Apple has changed the way we access DFU Mode, but fortunately, it is just as easy to access from new devices of Cupertino.
To do this, first thing to do is connect your device to your computer using a USB cable certified by Apple, because otherwise it might not work properly.
Once connected, we must simultaneously press the power button and volume down for about 10 seconds.
Subsequently, these past ten seconds, release the power button while still pressing the volume down button until iTunes show us a popup stating that it has detected a device in recovery mode.
Finally, if all went well, the screen of our iPhone 7 will become completely black and we can restore through iTunes without any problems.
In short, you see, although Apple has changed the mint to enter DFU Mode, it is still quite easy to access it, so if you think your iPhone has a problem, do not hesitate restorer using iTunes previously accessing mode.
