My Flip Mino HD stopped working (wouldn't turn on) after just a couple days of taking it out of the box. I followed up to step 13 (removed battery), then reconnected the battery and re-assembled it. I was flabbergasted when it turned on after I pressed the power button. I think disconnecting/reconnecting the battery is what reset it (had tried pressing the 'reset" button in the tripod socket but that had not worked for me). Thanks for saving my Flip from the trash!
