Updating your Fitbit tracker can take several minutes and is demanding on its battery. While performing an update we recommend keeping your tracker plugged into its charging cable.
To update your tracker follow these steps:
- If your tracker isn't charging, make sure that it's still nearby and that your wireless sync dongle is plugged into the computer.
- Verify that you're using the right version of Fitbit Connect:
- Click the Fitbit Connect icon and choose Open Main Menu..
- Click Troubleshooting. If you have a Mac, you should see "Fitbit Connect 188.8.131.5263." If you have a Windows machine, you should see "Fitbit Connect 184.108.40.20612." However, if you have a Mac running OSX 10.5, you need "Fitbit Connect 220.127.116.1110." If you have a Windows machine running XP, you need "Fitbit Connect 18.104.22.16811."
- Click the Fitbit Connect icon in your system tray or menu bar and click Main Menu. For best results, keep Fitbit Connect running in the foreground while your tracker updates. (In other words, don't minimize it or hide it behind other windows.) If you cannot find the Fitbit Connect icon on your computer:
- On a Mac OS machine, enter "Fitbit Connect" into the Spotlight search box. On a Windows machine: enter "Fitbit Connect" into the Start menu search box.
- If a search on your computer does not bring up Fitbit Connect, you may need to reinstall it from http://www.fitbit.com/setup.
- From the Main Menu, choose the Check for device update option.
- Log into Fitbit.com using your account email address and password. Fitbit Connect will perform a sync and then look for an update for your tracker.
- If an update is available, Fitbit Connect will display a progress bar until the update is finished. If your tracker has a screen, you'll also see a progress bar there. Keep your tracker close to the computer. When the update completes, a confirmation screen appears. Your tracker will now restart, and you can continue using it with the latest update applied.
- If the update fails to complete, try restarting your tracker using the instructions in How do I restart my tracker? and then trying the update again.
- If the update still doesn't complete, try updating using a mobile device.
