What type of  device are you using to set it back up.

On the Blaze lets do a Shutdown through the settings menu, now press any butyon to restart . 

There is no need to bring yge Blaze back to as new state.

Now lets restart the phone, lets turn on Bluetooth and tell the phone to forget the Blaze, you can leave Blaze classic aline,  

Now do an add tracker .. 

Does the app find the Blaze ? 

Does the blaze give a 4 digit code?

Does the app let you type the 4 digit code in?

Now wgat haopens.
