It isn't possible to retrieve any deleted information from your Orkut profile. Once you delete a scrap, testimonial, photo, etc., there is no way to restore that content.
You will have to ask your friends to re-send scraps or testimonials, and you can send or upload new scraps, photos, videos, etc. to your profile again.
Also note that it isn't possible for us to transfer the contents of a removed or inactive profile to a new profile.
