Blaze refusing to sync

[Zachmware]

I have a blaze and it will not sync. I tried unpairing it from my phone but now I can't pair it again. Do I have to delete the tracker and lose all my unsynced data?

I have been trying to Sync since  about noon.  Unable to do that.  I have deleted application.  Turned Blaze on and off.  Unpaired and repaired Bluetooth.  It looks like it is going to sync,. Says it is looking, then syncing but step number remains the same.  Frustrating.   And other suggestions?

I'm not sure if turning the Blaze off and on does the same as a restart but a restart does no harm so is worth a try:

1. Press and hold the Back and Select buttons (left and bottom right) until you see the Fitbit logo on the screen. This should take less than 10 seconds.
2. Let go of the buttons.

Restarts are known to not always work though so give this a few tries. If it still won't sync after that then there are some more troubleshooting ideas in this help file: http://help.fitbit.com/articles/en_US/Help_article/1866

Thank you for the tips, Steve. I did try restarting a few times. My latest problem is that I figured I could solve the problem by "forgetting the device" on my phone, then pairing again. No such luck. The blaze doesn't want to communicate with the phone and the app seems to want to stay out of it because, for the life of me, I can't find a way to "repair Bluetooth connection" without deleting the device and losing all my precious, precious data.

Your data shouldn't be at risk as it's held on the fitbit servers and not on the phone.

Correct me if I'm wrong, but I believe that, although the data that has already been synced is safe, the data that is stuck in my tracker from the past week is at risk. When you tap the garbage can icon, it warns you that unsynced data will be lost. 

[SteveH]

That's correct. My apologies I thought you were considering deleting the Bluetooth connection from the phone's settings rather than deleting the tracker from the fitbit app.
