How To Put Your iPhone into DFU Mode

15 12 2008

This tip is the most popular way while unlock & jailbreak due to upgrading or downgrading you iPhone. Just for remind, the timing is very important here because its very tricky. But don’t have to worry because you can do it again if you fail to do so.

To do this you need to turn your device off first. When it is completely off, push and hold the power button. Count to 5 and then push and hold the home button(keeping the power button pressed down still). Count to 10 and then let go of the power button(keeping the home button pressed down). Count to 30 and you should hear some notification on your PC or Mac that the device has been put into DFU (Device Firmware Update) mode.
