well you can use a third party data retieval software but if you've already fiddled around your laptop in hopes of trying to get anything back...you're not going to get anything retrieved.
Data is written as sequences, they follow a route. When you delete a file, its not physically removed, a small part of it is logically traced onto the drive. If you did other things after deleting files from recycle bin, then these routes were rewritten with new ones. Retrieving these lost routes become a hassle and its better dealt with by large retrieval companies.
almost forgot, welcome to the forums!
