iPhone 5S DFU Mode – How-to Tutorial

SPONSORED LINKS

As an iPhone, iPad or iPod Touch user, you will become familiar with many different terms, one of which is DFU Mode.  DFU stands for Device Firmware Update and, as the name implies it allows you to change the firmware version your device is currently running.

When your iPhone 5S is in DFU Mode it will be able to communicate with iTunes but will not load either the boot loader or iPhone operating system – this is where DFU differs from Recovery mode,  2 terms that people constantly confuse with each other.

DFU Mode is used when you want to downgrade your iOS or use a custom IPSW, usually during jailbreaking or unlocking the SIM.
