Changing wordpress theme name without losing updates

Any wordpress experts out here?

I would like to change my wordpress theme name without losing update functionality.

I am now using a child theme and I changed the theme name by changing the folder, style.css and database names, but you can still see the theme parent name in the source code.

What is the best way to hide the theme name in the source code?

This plugin seems to do what you want, I have not tried it, but it has a lot of reviews .. Try it on another install first .. =)
