I'm not talking about an Android TV box, but an actual smart TV. It would be nice if I had a high-end, 4k HDR enabled TV in my living room to watch Youtube/Kodi/Live TV or for emulators, which is one of the main reasons I want one. But it would also be great if I could root it and use most features a rooted phone would have, and install a custom recovery like TWRP/CWM so I could restore if I ever messed it up. I wouldn't plan to install a custom ROM because it would not be optimised for my TV/incompatible/impossible. Like I'd just find myself not being able to select inputs or use the TV tuner if I installed a custom ROM, if it were even possible and not entirely pointless to.
Does anyone know if it's possible to root and install custom recovery on an Android smart TV? I tried Googling and found close to zero results, my best guess is that there may be a few models that are hackable, but most of them are pretty old. Most TVs are running Lollipop, which is a decent version of Android but I fear will soon be no longer supported by Google/other apps in the near future. (After all, it only came out after KitKat). I'm looking for a TV that has ample RAM/CPU speed so it doesn't become sluggish over time, especially when rooted and with hacks installed (and antivirus running in the background). Basically something I can use for a good 10+ years.
Any help appreciated, sorry for the sloppy writing but I'm currently high as a kite.
EDIT: First post on the sub, it might just be me being a little paranoid but just to make it clear, I read the rules very carefully and I am not asking for any help with Kodi/other illegal stuff (just because I mentioned it).
