How are you connecting to the H9?  Over USB or Bluetooth?  And from what kind of device are you connecting to the H9?  iOS, Mac OS X or Windows?

You may try to reinstall your H9's firmware using the Direct Updater. You would need to use USB to connect to your PC/MAC to do so. You may download the Direct Updater here:
