In upgrading my sound system, when I plugged my FireTV back in, it wouldn’t boot past just showing the Amazon logo. After becoming quite frustrated, and trying a number of other suggestions, I decided to swap out the HDMI cord after reading that the FireTV required a high speed (1.3 or better) HDMI cord… and… yep, problem solved. Hopefully this saves some other fool(s) some time.
Still broken? Leave a message in the comments and I’d love to help. Otherwise, checkout Amazon’s latest FireTV.
