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:
