Hello @simon, I finally managed to downgrade my dumb TV !! Many thanks to the method by @smx, the process worked like a charm. Thanks a lot once again for all your help and patience.

Hi @smx, Thank you for share this method. I tried it yesterday and sure it is working good. I was changed my firmware version from 3.30.05 to 3.20.05. My tv model is LG 49UF8507.

Hello everyone. I'm smx, the author of the downgrade tool on https://github.com/openlgtv/nsu_emu. I noticed this topic after a guy mentioned it in the (mostly silent) openlgtv IRC channel. To reply to people saying that LG added a security check: i didn't do any change since my initial Netcast version, it just works as is. There could be multiple reasons as why the LgTvUpdater tool doesn't work, but i didn't check as my tool shares no code with that tool, it's just a different implementation. I actually had my tool in private testing within some friends at openlgtv before LgTvUpdater got released. After it got released, i then thought about releasing my version to the public aswell (no point in keeping it private anymore, and many testers were also gone), so it has some rough edges (like not being an easy to setup tool). But I am currently working on an updated, stand alone version, that should be easier to use and configure than the current one. So stay tuned Oh, and happy to be part of this forum
