The full name of DFU is Development FirmwareUpgrade, which means the forced upgrade and downgrade mode of iphone firmware.

IPhone has two special modes: one is the official recovery model, with the iTunes logo and USB cable displayed on the screen. The other is the DFU mode we use when jailbreaking, which is also called forced recovery mode. This mode does not show anything on the iPhone screen and is in a black screen state, so it has always been a difficulty in jailbreak operation.

Mode of entry:

1. Turn off your iPhone.

2. Press and hold the switch key and Home key at the same time.

3. When you see the white Apple Logo, please release the switch button and continue to hold down the Home key.

4. Open iTunes and wait for it to prompt you to enter recovery mode, then press and hold the shift key on the keyboard, click "restore", and select the appropriate firmware to restore.
