DFU stands for Device Firmware Update. You can choose this mode to upgrade your iPhone to the preferred iOS version. For instance, while downgrading your iPhone from iOS 12, you will be able to install iOS 11.2 or even jump over to iOS 10 (if your device is compatible with it). In this regard, it’s different from Recovery Mode that installs only the latest available iOS version on your iPhone.

Aside from letting you update your iPhone, DFU mode is also known to be a trusted solution to troubleshoot stubborn issues that haven’t been resolved by traditional restore or even Recovery Mode. Another significant thing worth noting is that when you put your iPhone into DFU mode, the device is able to communicate with iTunes even without activating boot loader. Hence, it has got the ability to bring your iPhone back into action even from a virtual death!
