If you want to reset them to new, just follow the instructions in the factory reset FAQ.
If you want further assistance, consider your words more cautiously. If I were a Sonos employee, I certainly wouldn't want to assist someone who trashes my product.
In my experience, the set up and maintenance of these speakers has been quite easy. It sounds like you haven't had that same experience. If you would like, there are many folks on this forum who would be willing to assist you, if you don't punch them in the face first.
