Performing a DFU Restore on a Mobile Device

A device firmware update (DFU) restore should only be performed if you cannot restore your device using Jamf Now, within settings, or by plugging your device into a computer with iTunes. If none of the above restore methods are available or work, you should continue with the following steps.

Note:

There are different DFU processes for different device types. For more information on these processes, see the following article from Apple's support website: https://support.apple.com/HT201263.

  1. Power off the device.
  2. Plug your mobile device in to a computer with iTunes installed and open iTunes.
  3. Press and hold down the Sleep/Wake button and the Home button together for 8 seconds.
  4. Keep pressing down the Home button, but release the Sleep/Wake button after 8 seconds. Eventually, a message will pop up in iTunes saying, "iTunes has detected a device in recovery mode." Click OK.
  5. Let go of the Home button and click Restore in iTunes.
