How to Put an iPhone into DFU Mode

You can fix many iPhone problems with something relatively simple like a restart. However, more difficult problems might require a more comprehensive approach, called DFU mode. Here’s how to put an iPhone into DFU mode.

How to put your iPhone into DFU mode

Important: If you plan to use DFU mode, do so at your own risk – you take responsibility for any undesirable results.

Putting a device into DFU mode is similar to recovery mode. Here’s what to do:

1. Connect iPhone or other iOS device to computer, then open iTunes.

2.Hold the button Sleep/Power (located on the top of the device) to display a slider, then drag the slider to the right to turn off the device.

If the device does not turn off, continue to hold the power button.power and buttonhome page pressed after the cursor appears. Eventually, the device will turn off. Release the buttons when the device turns off.

3. When the device is off, if you have an iPhone 7 or newer, press and hold the button Sleep/Power and the button volume down.

If you have an iPhone 6 or earlier: When the device is off, press and hold the button Sleep/Power and the Home button at the same time.

4. Hold these buttons for 10 seconds.

Note: If you hold for too long, the device enters recovery mode instead of DFU mode. The Apple logo appears when the device enters recovery mode.

5.Release the button Sleep/Powerbut hold the button home page (or the button volume down on an iPhone 7 or newer) pressed for 5 seconds.

If the iTunes logo and message appear, you pressed the button too long and need to start over.

6. If the device screen is black, it is in DFU mode. If iTunes recognizes that the iPhone is connected, you are ready to continue.

7. If you see any icons or text on the device screen, it is not in DFU mode and you will need to start over.

What is DFU mode, anyway?

iPhone Device Firmware Update (DFU) mode makes low-level changes to the software running the device. Although it is related to recovery mode, it is more comprehensive and you can use it to solve more difficult problems.

When an iOS device is in DFU mode, the device is powered on but has not booted the operating system. Therefore, you can make changes to the operating system as it is not yet running.

When to Use DFU Mode on iPhone

For most ordinary use of iPhone, iPod touch or iPad, you won’t need DFU mode. Recovery mode is usually the only thing you will need. If the device is stuck in a loop after updating the operating system or the data is so corrupted that it won’t work properly, recovery mode is your first step. In most cases, use iPhone DFU mode to:

  • Downgrade the version of iOS running on the device. Do this if for some reason upgrading to a newer version damaged the device or caused apps to stop working properly. Avoid this if possible, but it may be necessary in rare cases.
  • Jailbreak the device or un-jailbreak it.
  • Delete an expired iOS beta.
  • Fix iPhone that won’t boot after Apple logo.

Putting the device into DFU mode may be necessary to resolve some situations, but it is important to remember that it is potentially dangerous. Using DFU mode to downgrade the operating system or jailbreak the device may damage the device and violate the warranty.
