DFU stands for Device Firmware Update which reloads the software and the firmware of your device. This could be used in case the iPad is set up correctly (more about it you can find in How to set up iPads?) but not working fine and when the first troubleshooting steps for an iPad weren't helpful. Usually, this step is used as a last resort since after it all data will be removed completely, and that's why it's useful for enrollment processes while the device is empty.

To make the hard reset in DFU mode (Device Firmware Upgrade), please, follow these steps:

1. Connect the device to your computer with already installed iTunes using a USB cable.

NOTE: Make sure that you're using the latest version of iTunes

2. Hold down both the Home and Lock button for 10seconds.

3. Then, release the Lock button while continuing to hold down the Home button for another 10 seconds.

NOTE: If the Apple logo appears on the iPad screen, the Lock button was held down for too long.

4. If everything is done successfully, iTunes will alert you that the device was detected in DFU recovery mode. The iPad screen, in this case, will remain switched off.

NOTE: If your device shows a screen telling you to connect the device to iTunes, retry these steps again. If you can’t update or restore your device with recovery mode, or you can't use recovery mode, please contact Apple Support.
