Fitbit Charge 2 will not update

[Wolfgabe]

So recently I received a Fitbit charge 2 from my sister as a Christmas present but for some reason the darn thing just refuses to update. Everytime I try the app either fails to connect to my fitbit or it shows the update progress bar but goes nowhere before it quits. I have tried restarting my phone and tracker numerous times but no luck. Any suggestions?

@Wolfgabe A warm welcome to our Community!

Let me help you with the Charge 2 firmware update and thank you for troubleshooting this issue. Try clearing the link between your phone and your tracker by doing the following:

• Go to your phone's bluetooth settings and remove all devices listed there.
• Restart your phone and restart your device. 
• Check that no battery saving app/feature on your phone is affecting your Fitbit app.
• Also, if you are using an Android device, check that your app has the necessary permissions (settings > apps > Fitbit > permissions) and make sure bluetooth and location services (GPS) are on. 
• You can find troubleshooting instructions here.

Let me know how it goes.

I restarted both my device and phone and cleared my bluetooth settings as well as made sure location permission was on but still nothing. I might add I received my fitbit used so I am not sure if that makes a difference or not
