How to enter iPhone in DFU-mode, how to exit it

The DFU mode (device software update) is not the same as the recovery mode. Unlike the latter, it tests the current operating system that is installed on the device, and allows you to update or roll back it. If you get error messages trying to restore the settings in iTunes, it is likely it will help you. DFU (or Firmware Upgrade) allows all devices to be restored from any state.

As mentioned above, DFU is not a recovery mode that helps you connect to iTunes. In DFU, the backlighting of the iPhone screen looks different, and the display remains blank. If you have something on the display, you are not in this mode.

Method 1

Connect the phone to the PC and then turn it off. Press the Power and Home buttons, hold them simultaneously for 10 seconds. Then release Power, but continue to hold Home until the computer starts to emit sound signals that are similar to the sound of recognizing the USB device. If you managed to turn on the iPhone mode DFU, the screen should not show anything.

Having problems? Try to change 10 seconds for a slightly shorter time - 9 seconds, then 8, then 7. It's complicated, but so you can enter your device into DFU.

Method 2

Connect your phone to your PC and set up sync. Then, hold Home / Power until the phone turns off, within 10 seconds.

Then, continuing to follow the instruction on how to enter iPhone into DFU mode, hold Power and Home simultaneously for 10 seconds.

Release Power, but continue holding Home until the computer starts beeping . You will be able to see that you entered this mode when the contents of the screen change noticeably.

Instructions on how to enter the iPhone into the DFU mode, as you can see above, has several ways, each of which is quite simple. However, it is important not only to correctly enter the device into this mode, but also to deduce from it.

So, to exit DFU mode, just hold down the Home and Power buttons at the same time until the Apple logo is displayed on the gadget's screen.

Also it is worth remembering that in Apple TV (2G) the connection of this mode is slightly different. To do this, you need to connect the device to the computer using a MicroUSB cable.

Then it is necessary to force the device to reboot by holding down the "Menu" and "Down" buttons simultaneously, for six to seven seconds. Press Menu and Play at the same time immediately after the reboot, until the message appears in iTunes that the device detected Apple TV in recovery mode. Exit this mode can be almost the same as in other devices.
