Please restart your Fire TV Device & Hold the HOME Button on Remote for few seconds (30-40 seconds). OPTION 1- go ahead and press down the home button for about 40-50 seconds (the button with the little house on it). If that doesn't pair the remote try other options. OPTION 2- Pres down the play/pause button for about 40 seconds. If that didn’t work OPTION 3 Press down the HOME and PLAY/PAUSE button for about 40 seconds. One of those 3 options will work for you.
