What I didn't mention is that I specifically looked for older TV on the second hand market to find a hackable model.
I mean, I didn't wanted to buy a brand new one anyway, it's very expensive and I don't need latest AI features. I found a year old model with firmware that was listed as supported by the jailbreak at the time
I’d do exactly as you did. It’s pity it didn’t work for you. I’m on the market to buy a TV (not hurrying though), so I’m not sure what to do here. I’d like to have Dolby Vision (otherwise why would I want a TV if my computer display is good enough for everything else), so perhaps that worsens things. As otherwise I’d just pick any TV, even FullHD (not 4K), and even not smart (attaching some SBC with Kodi to the back). But ideally I’d prefer to jailbreak it and have Kodi installed without any extra device. Now I’m puzzled whether these lists of ‘compatible’ TVs are trustworthy.
