A:AnswerI recently bought the 50" Insignia Fire TV, and the bottom two screw holes ate indeed at different depth. Top screws 35mm, bottom 12mm. Both M6 screws for top and bottom. Not very intuitive.
A:AnswerTo update your Insignia 42" Class F20 Series LED Full HD Smart Fire TV to FireOS 7.6.6.8, you typically wouldn't need to download firmware directly from a website. Instead, firmware updates for Fire TV devices are usually delivered over-the-air. Here's how you can check for updates. Make sure your television is connected to the internet. Go to "Home" > "Settings" > "Device" > "About" > "Software Version" > "Check for updates".
