How to put your iPhone or iPad into DFU modeDFU mode is the last step on the iPhone, iPod touch, and iPad troubleshooting ladder.
Whether you want to jailbreak, un-jailbreak, update from an expired beta, or need a solution when nothing else is working, Apple has a solution for you: Putting your iPhone, iPod touch, or iPad into DFU (Device Firmware Update) mode can be your last, best hope for success.
DFU mode can help you get your phone back into working order, putting your iPhone into a state where it can still communicate with iTunes on Windows or Mac and be restored, but it won't trip the bootloader or iOS, in case your software has become royally borked. This allows your iPhone, iPad, or iPod touch to be restored from any state. DFU mode requires a bit of timing and can take practice to get right: If at first you don't succeed, don't be afraid to try again.
