Waitec Shuttle: is it a rebadge?

Hi, a friend of mine just gave me his Waitec Shuttle (8x4x32) because he won’t use it anymore.
I googled to see if any firmware oc was possible but didn’t find anything useful. Somewhere I read that some Waitec are Liteon rebadges, other ones are Philips rebadges.
Does anyone know if this drive is a rebadged one? Is it possible to upgrade it to some newer model?
