Hard boots should be fine. If you don't know much about the registry, you'd better not move. If it doesn't work well, it will completely paralyze the hard boot mode of P800/P800W/HTC3300/T version: hold down the keys with "-"on both sides of the mouse, poke resert with a pen, and press the dial key to let go when prompted. Or, directly in the settings-just reply to the factory settings.
