DFU mode is a deep recovery state built into the bootrom (SecureROM) of all Apple devices. It is hardcoded into the hardware during manufacturing and cannot be modified by software updates. When an iOS device cannot boot normally—due to a corrupted operating system or a failed update—DFU mode allows the device to interface with a computer via USB to restore its firmware. pwndfu tool
