If your receiver is in fact a Clone, then it is highly unlikely that you will find the requested files on this forum, as it does not support Clones.
How can I tell if the receiver is a Clone and a clone of what?

It seems that most Chinese STB manufacturers and suppliers mention in their specifications that upgrade can be done by USB disk, but they don't mention where the files are located.

Actually I'm not looking for files at this time, just a user_db.ssu Channel List editor.
