I say "DFU mode" when loading hardware with iPhone without loading iBoot in the minimum condition, but in order to surely turn off the power it is only to switch to DFU mode. Although it is used when the iPhone or iPad is in bad condition, it is used to cure symptoms or to install an unapproved Apple application, but when in DFU mode, the iPhone sends commands other than the PC connected via USB cable It will not be accepted, you can not turn on the iPhone or turn on the light by external operation.
