By losing its “physical” home button, the iPhone 7 has forced Apple to review the handling to make a “hard reset” or switch the iPhone to DFU mode (useful for installing a Version of iOS).
Reset iPhone 7 and iPhone 7 Plus
This procedure is safe for the data and allows to force the restart of an iPhone 7 which would no longer respond to any crash.
- Leave the ignition button pressed (on the right side of the iPhone)
- Press and hold the lower volume button (on the opposite side of the phone)
- Hold both buttons down until your iPhone 7 restarts and displays the white Apple logo on a black background.

Pass the iPhone 7 in DFU mode
The DFU (Device Firmware Upgrade) mode must be used to force the installation of a version of iOS different from that proposed by Apple. For example, to perform a downgrade, which involves installing an older version of iOS when a beta (or official version) is a problem on your device.
- Turn off your iPhone 7 and plug it into a Mac (or PC) with the Lightning cable and make sure iTunes is launched.
- Press and hold the iPhone’s power button for 3 seconds.
- While holding down the power button, press and hold down the lower volume button. Keep both buttons pressed for 10 seconds. Note: the screen should remain black, if you see the Apple logo, you have stayed too long and have done a hard reset, so you have to start over.
- Release the power button but keep pressing the lower volume button for 5 seconds. If your iPhone 7 prompts you to connect to iTunes, it’s still missed. Back to square one.
- The success of the operation is confirmed by a dialog box in iTunes indicating that you are in recovery mode.
