Interested in Jailbreak or having trouble updating to the latest iOS release and need to put your iPhone or iPad into DFU (Device Firmware Update) mode? Some Jailbreaks don’t do this automatically, you’re often required to do it to downgrade your iOS, and sometimes iTunes gives your errors when trying to update from beta or GM firmware to final release. While DFU mode is straight forward it can also be a little tricky. We’ll go over the steps after the break.
(And yes, we really should have made this for Georgia before last week’s iPhone Live! podcast. Our bad…!)
DFU mode requires a bit of timing and can take practice so if at first you don’t succeed, don’t be afraid to keep trying.
- Plug your iPhone, iPod touch, or iPad into your Mac or Windows PC and make sure iTunes is running.
- Hold down both the Sleep Button (on top of your device) and the Home Button (on the front underneath the screen).
- Keep them both held down from about 10 seconds. If you see the Apple logo, you’ve held them too long.
- Let go of the Sleep Button but keep holding the Home Button for about 5 seconds.
- That’s it! Your iPhone, iPod touch, or iPad should now be in DFU mode.
If you’re curious as to the difference between DFU mode and and Recovery Mode, our own Ally Kazmucha explains:
Recovery mode will implement iBoot (basically a portion of the bootloader than runs an integrity check) which will not allow you to downgrade your device. DFU mode will still talk to iTunes but it bypasses iBoot which will then allow you to downgrade firmware.If you’re having trouble and need any extra help, check out our Jailbreak Forum.
