Hacking TVs was a favourite pasttime of mine. There's nothing quite like flashing a TV with AOSP such that it thinks it's 55" smartphone. Lock screen and all.

See if you can find a service manual for your TV. You'll want to get UART as soon as possible.

Just remember crashes are for chumps: https://gist.github.com/Benjamin-Dobell/bb13f6169aaa48625453...

PS. I think that may be my favourite piece of code I've ever written. Mostly because it's completely absurd but worked just fine.
