Serial

I had read somewhere that according to your serial you may need a certain key/chip my serial starts as LU581. Is this correct or are there certain keys that I should stick to. I did see a thread of this anywhere.

and one other thing also.. what is the chances of bricking it ,,, seeing as how it is the kids also, I would hate to brick it.

for that u can use wasabi 2 or d2pro9 v2....recommended chip is wasabi 2 as its more stable at the moment

so what is the easiest without saudering wires. a clip with this or is this it and what about bricking chances?

you shouldn't worry about bricking...that only happens when u update your wii with a game from the wrong region. You can only do that with a game, not from a chip.

d2pro9 with clip requires no soldering ......wasabi with clip requires one wire to be soldered for d2c....for d2c2 wiis d2pro9 will be the easiest using a clip
