The firmware update happens when the sensor needs an update.  The update requires a data connection (Wi-Fi or Cellular Data) to complete the process.  If still having problems, please delete the app.  When deleting the app, the sensor is automatically reset.  Before deleting the app, make sure you back up any videos to Blast Connect (requires a subscription) or save them to your device.  All metrics are saved to the cloud network with a data connection on your device.
