Actually I had a little luck. My board is the same of the link. The thing is... I´ll never try to take of the R. I don´t have the skills nor equipments needed. They could use a jumper to that setting. Terrible design.

Thanks for the reply... I´ll probably assume the failure and go back to the good ol' Raspberry. Because of this security issue, I don´t feel confortable to use it on my network... even as a game device.
