Hello all. I am new to the Dingoo and haven't even received mine yet. I purchased one from a seller in Beijing off Ebay and was curious what is some stuff I should do to it right out of the box? I'm not sure what the firmware is or if the serial number has an HK in it so I don't know what I am dealing with yet. Please remember that I am new to this, but I do know what I am doing with a computer to some extent. Thanks in advance for all the help and links if ya got any.
