How to resolve the “Fitbit firmware Update Failed” error?

Correct the date and time on your devices

The correct date and time on your devices are necessary for your Fitbit devices and apps to work. A problem with the update may occur if the date and time settings on your devices are incorrect and your Fitbit can’t sync properly.

This may be important if the problem occurs in a country that uses daylight saving time. In this context, fixing the date and time settings on your phone may solve the problem. For example, let’s look at the process on an Android device.

  1. Exit the Fitbit app.
  2. Start your phone settings and open Date and Time.
  3. Then turn off the automatic date and time and time zone setting.
  4. Now change the date, time, and time zone to match your region.
  5. Be sure to turn on daylight saving time.
  6. Next, launch the Fitbit app and open the “Today” tab.
  7. Now click on your profile picture and open the advanced settings.
  8. Then turn off the Automatically set time zone option.
  9. Now set the time zone for your region.
  10. Make sure it matches your phone’s time zone, and don’t forget to turn on daylight saving time.
  11. Now sync your Fitbit device, then reboot your devices.
  12. After rebooting, try updating your device to see if the problem is resolved.

Unpairing and forgetting your Fitbit device in your phone settings

An update error may occur if your phone’s Bluetooth settings (especially those associated with the Fitbit device) are incorrect. In this context, removing the Fitbit device from your phone’s settings and fixing the settings may solve the problem. As an example, let’s look at the troubleshooting process on an Android device.

  1. Exit the Fitbit app and open your phone settings.
  2. Then tap on Bluetooth, and then tap on the Fitbit device name (or the gear icon in front of it).
  3. Then tap on Unpair or Forget this device. If possible, remove any paired devices from your phone’s Bluetooth settings.
  4. Then disable Bluetooth on your phone.
  5. Now reboot your Fitbit devices and your phone.
  6. After restarting, turn on the Bluetooth on your phone and pair it with your Fitbit device.
  7. Now check to see if you can update your device.
  8. If this fails and the message “Try again” appears in the Fitbit app, don’t click it.
  9. Instead, minimize the Fitbit app (do not close it).
  10. Then turn off Bluetooth on your phone.
  11. Wait 10 seconds, then turn Bluetooth back on.
  12. Now open the minimized Fitbit app and press Retry to see if the problem is resolved.

Restart the devices

The problem may be caused by a temporary failure of communication modules and apps. As such, restarting the devices may fix the problem and thereby resolve it.

  1. Exit the Fitbit app on your phone.
  2. Reboot your Fitbit device and try the update again to see if the problem is resolved.
  3. If not, turn off your Fitbit device and phone.
  4. Now turn on your Fitbit device and wait for it to turn on completely.
  5. Then turn on your phone and see if the problem with the update is resolved.

Try a different network

The error may be due to restrictions imposed by your ISP. Also, the error may be caused by hardware limitations of some phone models, i.e. a model that uses the same antenna for Wi-Fi and Bluetooth. In this case, use a different network or cellular data of your device (not Wi-Fi) to update.

  1. Unplug your phone from the current Wi-Fi network.
  2. Now reboot your devices.
  3. Then connect your phone/device to another network or use your phone’s hotspot (make sure you are in the area with the best signal strength).
  4. Now try updating your Fitbit to see if the update bug is fixed.
  5. If it’s not, try using another phone’s hotspot as a Wi-Fi connection between your phone and your Fitbit device.
  6. Then check to see if the error is gone on your Fitbit device.
