A hard-reset will restore your device to its original state, and all information you have added to the internal memory will be erased. The procedure is easy:
- To hard-reset your phone, tap on the Menu button and enter Settings > Security > Factory data reset. Press the Reset phone button to complete the procedure.
- On the HTC Hero, you can also perform a hard-reset by pressing hardware buttons. While the Hero is turned off, simultaneously press and hold the Home and Back buttons, then briefly press the End call/Power on button. The reset process will start after a couple of seconds.
