After hours of playing around trying to reset my remote, I finally found a solution. It was blinking orange which indicates that it was having trouble pairing to the fire tv stick. I downloaded the Fire TV app on my phone and was able to control the fire TV that way, but I couldn’t control the TV volume. So I went into the settings area of the fire TV menu and clicked on the image of the remote (I think it’s labeled “remote and controllers”) and clicked set up new remote. I pretended my fire TV remote was the new remote and the app remote on my phone was the old one (they ask you to click on both the old and new remote to pair the one you want to the fire stick) and that did the trick.
