A:AnswerDisconnect it from TV like LG or Samsung or some other brands then re-connect to. And then, make sure you pick right brand of your TV on FireStick Max that you can see which one to connect FireStick’s remote to TV’s screen to control the volumes and on/off.
A:AnswerFiber Optic isn't necessary. You just need a good wifi connection without interference and then you need to find the right apps for what you want to watch. If it's freezing that much, maybe place it where it gets some air. They can get hot if smothered.
A:AnswerIf you're going for the whole Kodi/off the grid setup, this probably isn't the device for you. For one thing you're going to need tons of storage. For another, Amazon isnt keen to their products being hacked. You don't want to break tos and wind up with a paperweight. I suggest doing some research online. Reddit is always helpful (if you're respectful and willing to learn and do a bit of your own research)
