What you do is unscrew the big screw from the back of ur tama. Then the tricky part, taaking out the little screws! They are in the corners and are very small so be careful not to lose them!!then take your tama apart so one side is one one and another on the other but make sure not to tear any wires. then near thebattery look for the words debug and fill in the circle underneath with pencil. then close up and hit download!!
BTW I recommend not debbuging because it might mess up your tama and it is hard to reverse! Unless you want to buy another tama that's fine but go ahead and do what you like!!
