    What is Recovery Mode?

    iPhone recovery mode also termed DFU (Device Firmware Update) mode is used to perform firmware updates to an iPhone. Earlier, only Apple used the iPhone recovery mode via iTunes to update iPhone firmware, but nowadays many iPhone software developers are using the recovery mode, alias DFU mode, to perform firmware updates on their own. This recovery mode puts an iPhone into boot mode and doesn’t allow the operating system to load. The one and only purpose to use iPhone DFU mode is to perform low level programming tasks as performed with other mobile phones during flash mode.

    iPhone recovery mode is similar to the flash mode found on several other mobile phones used by mobile phone manufacturers to restore a phone to its factory default settings, perform firmware updates or used by developers to tweak mobile phone settings.

    How does recovery mode help?

    The iPhone operating system is similar to the operating system that we see and use on our desktop or laptop computers. The only difference being that an iPhone O.S is designed for mobile specific operations only.

    As with a corrupt Windows installation, you might face a corrupt iPhone update operation causing your iPhone to stick to a particular screen and in some cases, you may not be able to boot your iPhone.

    In such cases, you need to use the iPhone recovery mode to reinstall the O.S on your iPhone.
