What is DFU Mode?
DFU stands for Device Firmware Update, and it reloads the software and firmware of your device. DFU Restore makes low-level changes to the iOS that’s running your iPhone and is the deepest type of restore that can be done on a device. When you put your iPhone in the DFU mode, your iPhone is powered up, but it hasn’t booted up the iOS. Therefore, you can make changes to the operating system of your iPhone as it’s not running yet.
