No hard reset as in taking it back to factory settings by holding down the two soft key buttons directly below the screen, and then pressing the reset button with the stylus. You will the see a screen offering 'R' and 'X' (exit) choose 'R' to hard reset.
By the way does your device have a carriers name on it, or is it an HTC Tytn?
