What is DFU Mode on the iPad?
It stands for Device Firmware Upgrade. But is commonly used when your device is having problems and it wont even start. Lots of the needed times to use it are involved in the process of "jailbreaking’ your device.
To enter DFU mode…
- Connect the iPhone to your computer and launch iTunes
-
Turn the iPhone off (hold down the power button at the top of the iPhone)
-
Hold down the sleep/power button and home button together for exactly 10 seconds, then release the power button
-
Continue to hold down the Home button until a message appears in iTunes telling you an iPhone in recover mode has been detected
To exit DFU mode…
Hold down the Home and sleep/power buttons on the iPhone while connected to iTunes. Then just hit the power button as and this should reboot the device as usual.
And if you’re curious, yes this works all the same on an iPod touch.
