Part 6: Differences between DFU Mode and Recovery Mode

The most key difference between DFU Mode and Recovery Mode is iBoot. iBoot is the bootloader on iPhone OS devices, it acts on restore while iPhone is in Recovery Mode, iBoot makes sure that you are flashing a firmware version greater than or equal to a current one. Recovery mode uses iBoot during restoring or upgrading your iPhone while DFU mode bypasses the iBoot so you can downgrade the current firmware because there is no iBoot agent during the DFU mode.

DFU mode is not recovery mode. Recovery mode has a red iTunes logo that says connect to iTunes. In DFU mode, the iPhone screen backlight is not even on and the display is blank. If you have anything on your display you are not in DFU mode.
