Hi

Yes I have connected the player to my computer, I follow all steps of the guide.

Yes, tried it several times.

I cannot backup my old firmware, but I have another player (the same player) where I can backup it. With my player I can follow the steps without problems.

Hahaha I'm the seller xD

I think that it is phisically damaged, ¿why? well, this player is Metallic and the metallic case (the part where the chip samsung is) it's "dented".

Thank you for your reply!
