DFU (Device Firmware Update) mode is a special mode on your iPhone, iPad, or iPod touch that allows you to update the firmware without loading the operating system. This is especially useful when you need to reinstall the operating system without losing data. Unlike recovery mode, DFU mode bypasses the iBoot bootloader, so it can be used to install any iOS version without any restrictions. Additionally, DFU Mode can also be used to jailbreak your device and install custom firmware. Recovery Mode, on the other hand, uses iBoot to restore or upgrade the device. It can also be used to put your device in a state where it can be restored from a previous backup or from an iTunes restore image.
