Latest firmware/software for 55UB850T


I got a new 2015 model 55UB850T that has webOS. The product website says the latest version is 3.23.23 and the version in my TV is 3.23.13. However, when I choose the option 'check of updates' from TV settings, I get the message that no updates are available.




I tried downloading the files from the above link and the 7zip extract fails with message that file is broken. Downloaded multiple times and tried.


Any ideas how to fix this? I read in another thread that the latest version is 4.x, how do I get latest?


I am from India.

I think your TV is 2014 model.

The archive is no problem. Probably if you have a problem when downloading files.




Usually, the latest versions from the link below  are engineering test versions.

Here is a link to how to update.

If necessary you wear TV of the service center, a test version will invalidate your warranty.
