[AndrewFitbit]

ISSUE: Can't sync or pair Blaze with an iOS device

BLAZE FIRMWARE VERSIONS AFFECTED: (8.301.7) & (8.200.3)

iOS VERSIONS AFFECTED: 10.2.x

*** FIXED IN BLAZE FIRMWARE VERSION (8.301.8) ***

Still having trouble? Can't update or sync?

Read the difference between unbonding and unpairing first:

Unbonding - going into the bluetooth settings of your iPhone or iPad, selecting the Blaze, then choosing "Forget This Device".

Unpairing - going into the Fitbit app, selecting the Blaze, then choosing "Remove This Blaze".

*** DO NOT DO THIS TO TROUBLESHOOT THIS SPECIFIC ISSUE ***

Now that you've read that, try unbonding BEFORE trying to update your Blaze firmware (see screenshots below):

1. Go to your iOS device's Settings > Bluetooth > Find Blaze in the "My Devices" list.
2. Tap the info icon and tap "Forget this Device".
   
        

---

Okay, I've unbonded. Now what?

Try syncing your Blaze, then try to update the firmware.

Still can't sync or update? Here are some suggestions:

1. Try doing some standard sync troubleshoots
2. Sync/update using an alternate device (if possible)

This is still not working for me.  I have completed the steps to "forget" the device.  I have even reset the FitBit Blaze and my phone.  I restart the FitBit App and choose to update the tracker.  The process starts and says "Loading".  The progress bar gets about halfway and then just stops and  goes back to the tracker screen.

Update: I turned my Wi-Fi off and restarted the whole update process and it is now working.

Iks like I need to keep the fitbit app active in background (do not close the app) to allow it to send notifications when on android it works fine...

Thanks @Spidermad this worked plus you have to stay in the app and don't press anything or it'll fail!!!!!!!

I've followed all the above and it's still not loading the update.

Well I'm annoyed. Months of hitting the targets every day, this issue  comes along which  takes hours to fix and then I lose nearly 40000 steps that haven't been synced in the last  2 days 

[Tazy]

I had to completely restart my phone. It's working now.

Same issues, so frustrated.... can't get Blaze working.

15+ hours later and the app says my battery is full, my watch shows maybe 75-80% left. So i believe my battery brain is solved.  Tomorrow morning will be the test to see how much battery life is left after 24 hours.

now my blaze won't install the update.

My blaze is not taking this update to solve sync issue!!!!   What do I do!!!!

[mcracknell]

Why won't my blaze sync up? The new update is just sitting there, every time I hit update it sits and loads for a minute and then stops. My tracker is right next to me and is fully charged.

the update still dose not work. I got the update to download and update my blaze.  I also went to the notifications and turned them back on and they still won't work.  This needs to be fixed. 

[MadRedRhino]

My notifications will work on minute and then the other minute it will say not connected and the notifications.  I did the update and reset the notifications.  Please fix this.

Hi, I am unable to load the update to resolve the syncing issue with the latest iOS update.  It progresses to 50% and then fails. I have tried powering off and back on, disconnecting from Bluetooth but nothing has worked. Thanks

i just purchased my blaze and my phone can not find it when trying to set it up. how do i update the fitbit blaze if it hasnt been connected to a phone?

[Hincksy]

Updated my phone to iOS 10.2 - blaze tracker wants to update but operation fails- has difficulties syncing too doesn't recognise exercise despite setting watch does t appear on app!!

[abanuk]

Ive got the same issue myself. I cant sync and I can't apply the update 

[Kootenai.cule]

I warn you that this deleted 2 days of steps but got it  working. I went to Bluetooth and forgot the device. Went into the fitbit app and Removed the blaze in there. I deleted the app and reinstalled it. And it found the fitbit first time of asking. It then asked if I wanted to update and now it is okay. A royal pain in the **ahem** but it worked for me.

Thank you very much I will try that

Merry Christmas
