Fernando, this would only be possible if you could find the right NAND IC. It is very unlikely that you will find one that has the same physical property. The IC would have to fit the circuit board since it is a SMD components that would require a reflow of the existing board. You would need the IC and the template that fits the logic board. OF course, even then it might not work since the firmware may not accept the higher storage and mat not write to it.
