What's iPhone DFU Mode
Apple comes with two modes - a Recovery Mode and a DFU Mode - to help users update or restore their iOS devices when something goes wrong on the device (unresponsive, crack, malfunction, etc). While the Recovery mode loads iBoot bootloader but not the OS to restore your device to its original factory settings and install the latest iOS and firmware, the DFU mode bypasses the iBoot bootloader and gives you more flexibility to change and choose the firmware you want to install onto your iPhone.
When your iPhone is in DFU mode, it has a completely black screen.
