I don't get the hard-reset thing. Some people say it helps something, others say flashing already does a hard reset and doing a 2nd one does nothing. I'm more inclined to believe the later. When you flash, it starts the ROM with an empty flash. That's all hard-reseting does anyway. ...right?

Can someone give me any technical reason why doing a 2nd hard-reset would do anything at all?

...and when are you supposed to do it? After letting it boot all the way to the calibrate screen, or before then, or what?
