DFU stands for Device Firmware Upgrade.

DFU Mode allows the S5L8900 to be restored from any state. It resides in the VROM and is vulnerable to the pwnage 2.0 exploit. Unlike Restore Mode, you cannot exit DFU mode without restoring.

You might use iNdependence on Mac OS X to set your phone in this state (iTunes 7.7.0 is not supported yet), or use the manual procedure:

Method 1
  1. Turn off the device.
  2. Hold the home and power buttons simultaneously to turn on.
  3. Hold them both around 10 seconds, then let the power button go. Keep the home button pressed until the screen flashes and stays "black" but lit.

If the Restore Logo is present on the screen, you are in Restore Mode, NOT DFU.

Method 2
  1. When your phone is on and connected to iTunes hold the home and power buttons simultaneously until it turns off (ignoring the red 'power off' slider)
  2. Wait approximately 4 seconds.
  3. Release the power/mute button and keep home pressed until iTunes shows a message that it found a phone in Restore Mode.

Your phone should have a blank screen, which is DFU mode. If you see the Restore Logo, you are in Restore Mode and will have to try again.
