Protect Flash memory on ATMEGA2560 (SOLVED)

Hi, I've been looking for a few days to find info about this in the net. I downloaded the AVR Studio 5 and bought an AVRISP mkII from the Atmel store to follow the steps they explain on his website to block the security bites. The thing is that when I connect the Arduino Mega with the AVRISP mkII to my computer I can't lock the security bites on AVR Studio 5 cause that option doesnt exist for the ATMEGA2560 as ATMEL show on the tutorials.... So I have no idea how can I do that!! The idea is to…

Here's how to clone it...

Cloning Arduino Mega 2560

I have an arduino mega 2560 that controls a power supply and some other functions of another separate board. It is somewhat non-functional now but the person that originally compiled the board is not reachable. The board turns on but outputs the wrong voltage, so we wanted to try: Reflashing it (by copying the binary off it first?) or Cloning the binary onto another mega 2560 board I see from basic research that one or both are possible with avrdude but am somewhat lost on how to achieve this…
