I recently ordered an Operation System from BlackTheBlack on Underground Marketplace (http://unground6baopdio.onion/user/45b4ef4ff8598647). He sent the data very fast, only 30 Minutes after I ordered, he responded and sent me the link to the download. I had much issues with the activation when trying with other solutions, but the one he provided worked like charm!! The manual he provided was simple and easy to do.
I would recomend this Seller because of my great experience!!
Underground Marketplace.... That's a new one, right?
