I guess you did not see post #2 or first suggestion.

Testdisk does not always find files, and a few have said it showed files with full names, but then tried something else and never found them again. So if using testdisk, always copy files to another device immediately.

Photorec works, and there are tools to auto rename some types of files like photos.

Best to always have back up then you do not have to spend 3 weeks trying to recover data.
