Could you take a briked wii, with out a nand dumd and without boot2 bootmii compatability. Take this wii and dump the bricked nand and extract the key? If you could, could you then take a nand dump of a compatible wii and change the key, then flash that back?
Also, what do you think about the solderless method described here below?
Wii brick fixing. Using an infectus tutorial
And could someone not make some kind of clip or similare that would fit over the nand temporarily?
