Understanding DFU Mode

1
Put your device into DFU mode when downgrading. If you want to go back to an earlier version of iOS, you will need to enter DFU mode so that the old operating system software can be installed.
- DFU mode occurs before the device loads the installed operating system This allows you to change system files while they're not being accessed.
2
Put your device into DFU mode when jailbreaking. If you're jailbreaking your iPhone, you may need to put it into DFU mode to load the custom operating system. Not every jailbreak process requires you to do this.
3
Put your device into DFU mode when unjailbreaking. If you want to send in your jailbroken iPhone for warranty service, you will need to reverse the jailbreak process. This may require you to put your device into DFU mode. This is usually done as a troubleshooting step, when the device will not restore properly through iTunes.
4
Put your iPhone into DFU mode if recovering with normal recovery mode does not work. Sometimes, a firmware update may interrupt, causing corrupted files. It is advised that an iPhone is not force-restarted during a firmware update, as the iPhone may not continue with the firmware update. However, if an iPhone's firmware update is interrupted or the system memory is corrupt as a result of a process like jailbreaking, DFU mode ensures that the iOS device can be restored even if the memory is corrupt.
