    It should be a thing because most (all?) “smart TVs” run some variety of Linux, which, as Free Software, is supposed to guarantee the device owner’s right to modify the software running on the thing. However, in most (all?) cases, the practical ability to do that has been destroyed by subverting encryption functions against the owner in a process called Tivoization.

    In other words:

    1. No, it isn’t really a thing,
    2. It’s wrong for it not to be a thing, and
    3. You should be pissed off about it.

        I mean, they did it with phones too. Android is just Linux. That was one of the main attractions, for me at least.

        At first, many people and groups supplied their own phone OSes. There was a whole thriving community ecosystem. Then they started to make it really hard, locking bootloaders and including critical pieces of hardware that didn’t or couldn’t have open source drivers (look up WinModems for a very early example of this technique, it remains really effective) or otherwise required extremely convoluted methods to access and the phone might function marginally without some of these fully functional, but at least you could still install a custom ROM on it if you were stubborn enough.

        But even that wouldn’t last. Nowadays they’ve made it literally impossible to defeat the security on most phones, in the name of keeping hackers and criminals out, but really a big part of their motivation is blocking these pirate OSes that let you actually control the hardware and software in your phone, doing criminally nefarious things like stopping them from downloading ads (the horror!) and preventing them from funneling all your data and activities back to Big Brother (how rude!) and worst of all updating it with modern functionality after they’ve declared it “obsolete”. The goal going forward is to sell you things that you don’t and can’t control, so they can shut them down or make them gradually more and more useless and make you buy new ones forever. They want you to have a subscription for everything including physical objects without realizing that you’ve been forced to subscribe to their regularly-scheduled-disposable-device-replacement-plan for no actual reason.

        They’re coming for computers too, or at least they’ll try. They want control of everything we interact with. For profit, mostly, but I wouldn’t rule out other motives. It’s a powerful thing when you have control of everything people see and do.

          I could be wrong (I haven’t really paid attention lately), but I think the state of Linux on “smart” TVs is considerably more dire than the state of Android phones. At least with the latter, projects like LineageOS and GrapheneOS are a thing, whereas I know of zero third-party community firmware projects for TVs.

            Oh absolutely. Smart TVs are completely under the control of the technology and media companies with very little hope for freeing them, except that you can still plug a computer into them to bypass all the “smart” features and just use it as a dumb screen with a smart computer instead. But they always seem to put a few new stumbling blocks in the way of both those options every year. That loophole will eventually get closed, it won’t happen overnight, but they will keep eroding the functionalities and convenience of doing so until few if anyone wants to do that anymore.

            Cars are nearly a lost cause too, except where regulations say they must use some standard like OBD2 for “emissions reasons”, although that is obviously a limited scope and manufacturers try to find any ways they can to sabotage it or otherwise avoid it. Appliances and “smart homes”, all the way down to the light bulbs and LEDs, have plenty of proprietary, locked down, unrepairable technology in them too despite reliable open standards being available. The war for total control over our digital devices is in full swing and there’s no area of our lives from large to small that isn’t a battleground. People need to keep prioritizing the freedom of their devices because once they get these technologies and features entrenched it’s going to be very hard to work around them.

      It’s interesting to see some of the back-and-forth on this topic between different proponents of free software.

      I listened to this talk by Linus Torvalds a while back and it relates to the GPL license used by the Linux kernel and why the kernel hasn’t changed to GPLv3. Apparently Linus doesn’t find this practice by Tivo and other hardware manufacturers to be an issue.

        Yes, it’s a damn shame that Linus is weak on property rights.

        Because that’s what this actually is, by the way: violating the device owner’s property rights in order to prioritize the manufacturer’s temporary monopoly privilege over the software – which was only created for the sole and express purpose “to promote the progress of science and the useful arts” in the first place – above them.

            I think he needs to work with HW manufacturers and chip designers/manufacturers to get drivers. They’re always going to have some proprietary HW and FW and communication protocols somewhere in their stuff. I think if he pisses them off too much he has to to bit-bash or reverse engineer all drivers for loads of stuff - which is never going to happen.

    In principle, yes, and I believe a few small hobby projects have attempted to do this and support specific TVs. However, interest in developing a custom Smart TV platform tends to get siphoned away into a project where the output from your actual platform is displayed on the TV rather than running directly on it. Simply, it’s easier to develop and maintain support across different models.

    Why would you develop a custom TV OS that runs on one TV when you could develop it for any mini PC and immediately support all TVs? You’d have to develop your OS to run on each specific TV model which will make it quite hard to reach a critical mass sufficient to attract attention from developers and users alike.

    The juice isn’t really worth the squeeze. It’s not like TV vendors are publishing detailed hardware specs and drivers. Writing or even porting an OS is hard. Look at the state of the Android ROM scene, and that’s about as good as it gets when some vendors are actually attempting to open source their drivers. The difficulty is much higher and the interest lower due to the existence of a viable alternative.

    With that said, motivated minds have done it anyway. You just need to have the right TV for it.

    Usually that means trying to get Android TV working through USB, but it depends on what tv you have. If you already have an Android TV, just use a launcher like Projectivy. Most people just buy a media box: either an Android based one or apple tv and disable the “smart” tv altogether

      I’d imagine you could probably get into the android developer settings and disable all the telemetry stuff through adb and install a custom launcher like projectivity and that’d be the closest you could get to running a custom tv OS at least if you can’t flash it.

            Sceptre is cheapo stuff. And at least one brand of smart TV is wardriving to find networks behind your back (again, drunk, I can’t remember which right now) and creating mesh networks with other TVs of the same type.

                Learned skill. I spend a lot of time drunk and Android tends to do a pretty good job of guessing what I’m swiping.

                I also tend to reread what I wrote when I’m drunk. I actually generally do a worse job sober because I won’t double check my work.

                And it was signage displays for the dumb TVs I was thinking of, and Sharp TVs used to have unsecured wireless networks that you couldn’t really turn off, so they’d make a mesh with other smart TVs. I believe I’ve heard the same thing about Samsung as well.

                Now it’s time to go jog myself sick.

      They simply don’t exist anymore. The only choice is to do this with a smart TV and never connect it to the internet.

    It’s much easier to run a HTPC on something small like a Raspberry Pi, or an NVIDIA Shield. The hardware on your TV is probably the bare minimum to run its own smart features, and replacing the firmware doesn’t guarantee that the TV isn’t still phoning home with your data.

    I’d think most people woud go for a cheap used ultra Small Form Factor pc or raspberry pi set up as an htpc. Plug in to either tv screen (via hdmi ) or monitor / projector directly. Never connect the tv to the internet - or even to your LAN if you’re really paranoid. You can arse around with a remote control a bit bodgy, or just use wireless Keyboard/mouse.

    I cant imagine spending the time to jailbreak a tv to get less functionality for more hassle - but i’m sure some crazy will have done it - good luck finding them though.

        A TV usually comes with a remote, a monitor doesn’t. Additionally, you can use it to watch linear TV if you don’t feel like making a selection.

          I have a “smart TV” and I plug it into my receiver and use it as a monitor. I use the term smart TV that way, because it is more than 10 years old when TVs were just starting to have these features. I should also point out that the receiver does all of the spying that the TV isn’t doing. Not sure what I’ll do when the TV dies.

            Similar for me. I have an old Philips “smart” TV (actually today it is very dumb as basically all services are disabled and all apps heavily outdated) which I occasionally use for watching TV, but most times I use the attached Raspberry Pi with Kodi for watching German public broadcaster’s Mediathek, Youtube or Amazon Prime.

    Yes, it’s called jailbreaking. That said it basically never happens because TV’s are pretty much shitty monitors with cheap digital encoders, and you can buy an encoder and a good monitor for way way cheaper than rewriting an OS.

    Nvidia shields with an alternate home screen have been a good solution for me? TV isn’t connected to the network directly, just to the shield.

    I’ve got RetroArch, Plex, Spotify on each of them - that sort of stuff.

      I was thinking that if somebody knows how to do that, they probably also have an opinion on which brands of TV are better or worse for it.

      I don’t own a TV right now but plan to in the future.

        Ah, well, the biggest thing you have to worry about is that most vulnerabilities that would allow users to get ROOT access have been patched for old and new TVs, so you might want to be selective if you don’t want to do it the hard way. You need to know which TV OS you’re dealing with before you can look for the necesary tools.

        The hard way is removing the SoC processor from the board, buying a custom mount for it, and using the debug pins to flash the OS. Most of the legwork has been done already for this method. https://www.synacktiv.com/en/publications/i-hack-u-boot

        Something to keep in mind is that the processors in smart TVs are almost always pathetically slow. Also, the streaming services compatible with these TVs require hardware encryption so if your modified OS mimics the old one but isn’t verified then they will refuse to run. You would get better performance from using a computer connected to the HDMI port, or even a Raspberry Pi as your TV Box.

        Replacing the OS completely is likely possible for every single TV on the market, but not very likely for any of them because nobody with the skills sees any value in it.

      I don’t know how remotes work, physically, but they gotta send some sort of code to the TV. If your TV’s OS can intercept that message it can choose its own response mapped to whatever you want to happen. Something akin to remapping keys in your keyboard.

      I would assume, anyway. I could be wrong.

    What I did was bought a “commercial” television that’s intended to either be put in a waiting room and tuned to Fox News all day, OR used as digital signage. It’s not quite an Arby’s menu board because it’s still obviously a television, has a tuner and such, but it has no “smart” TV in it and the backlight isn’t as “won’t survive a run of Breath of the Wild” like the TCL televisions my parents own. Then I slapped a Raspberry Pi 4 on the back with OSMC on it. Meanwhile I did replace my small form factor desktop gaming rig, so I have a Ryzen 3600/GTX1080 rig sitting unplugged under that television waiting for me to build up the gumption to switch over to it.
