A DFU restore should only be performed if you can not 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 below.
- Power off the device
- Plug your iOS device into a computer with iTunes installed and open iTunes.
- Press and hold down the Sleep/Wake button and the Home button together for 8 seconds.
- Keep pressing down the home button, but release the sleep wake button after 8 seconds. Eventually, a message will popup in iTunes saying, "iTunes has detected a device in recovery mode." Click OK.
- Now, you can let go of the Home button. Click Restore in iTunes.
