Where can I find the default code files for the Debut Theme?

[RENE-]

Hi,

I need help finding the Shopify DEBUT THEME default code files.

(I understand this theme is no longer available). I need this because my developer has caused so many issues on my website, that I need to verify some of the original codes. The problem I am having now, since I no longer have the untouched default code... is that my developer keeps causing issues, and fixing those, then fixing those etc... to the point that nothing works anymore. I need the default code, so I keep revert some of his very bad work to the default, without starting the entire over. Any help would be very much appreciated!
