Can't install ATV verison 4.4.1?

I am trying to install version 4.4.1 and it is telling me that the version is old and to download a newer version. I am doing this for I reset my whole ATV back to factory and upgraded the OS to the current release. I was previously on a very old version and can’t find the original ATV files.

I can’t find the right version to install from scratch. I purchased an ATV black version, but that is the wrong one.


Where can I get the right version that will work with my newly reset ATV silver?
