What Is DFU Mode?

DFU is an acronym for Development Firmware Upgrade. DFU mode is another mode on iOS that allows you to force upgrade and downgrade iOS firmware. It is also known as developer mode for iOS. As the name suggests, DFU mode is more suitable for developers. If you are new to iOS, use this mode with caution.

DFU Mode vs Recovery Mode

The biggest difference between DFU mode and Recovery mode is whether iBoot (bootloader) is loaded, which is a remote power controller that allows you to control, reboot, and cycle power to any connected device from a distance. In Recovery mode, Finder or iTunes will load iBoot to restore and upgrade your firmware, while in DFU mode, Finder or iTunes will bypass iBoot, so you can use this mode to jailbreak and downgrade your iOS.
