Hey @user1DtQygHprR ,
Usually the firmware is meant for the device it's installed on and trying to install one from a different device may actually harm it. I hope this was helpful please leave a like and mark accept as solution if it was.
I definitely would not recommend it either as the above product expert has mentioned. These updates are specifically for that particular TV. It could either reject the update as it is not compatible or even cause issues with its current software.
Are you currently experiencing an issue with your TV which is why you are exploring the update option ?
