I bought this device and not able to register that, when I had word with Amazon customer care, I was told that this device is marked stolen and is blacklisted. That's the reason I'm not able to register the product. How can someone sell me a product that stolen?? Amazon is clever enough to keep a track of their stolen devices. What if there are more products on this website that are simply stolen and being sold here as a certified refurbished? I'm gonna take some legal action on these people and the seller. Don't ever purchase anything from this seller or backmarket as they failed to keep their promise.
