@JAMES4578 Thank you. Although not a direct equivalent, it wasn't too far off (2141) I have the current one. I was looking for a list of them all. I purchased it in 12/2021 but never took it out of the box. I just opened it a couple days ago and stupidly updated it, thinking "it's been about two years, lets get it up to speed." As soon as I did, it started sluggishly lagging for painstaking amounts of time on menu & setting selections, and button presses in general. As well as removed the coveted setting "Allow Unknown Sources." When I started digging into rolling my tv back to it's factory firmware, I was introduced to Samsung's seemingly dishonest practices about their firmware updates, (planned obsolescence) as well as their company's stance to double-down and refuse to allow users to flash the firmware back to a previous update, going so far as to not even display on their website what the last few updates were. My tv's only been in use for less than three days. So I was looking for what the factory firmware was, as this was what my tv was using since I hadn't activated it for two yrs. I stupidly didn't take note of it when I updated it. (Didn't think I had to) I don't know exactly what I will do with this info, since I would still technically need it to be a link to download it, but I'm still searching. There's no way I should have to deal with this only after three days. I deeply appreciate your help and any advice you can provide regarding this matter.
