Hello,
I successfully updated, thank you!
I have a question though, are you familiar with any method to root the TV or use it successfully as a kiosk? Applications don't start automatically on boot and that prevents it from being any good for a kiosk. I could replace the video that starts in Store Mode, that would work but I need root for it. I tried patching the kernel inside the ZIP with Magisk and replacing it but it gets caught by verification during flashing, even in Download Mode...
