Since you managed to format your NAND due to not reading, I strongly suggest you stop and look through all the guides and stickys. Everything you need to know about this (and all questions answered) if you take the time to read.
Bear in mind that when you have your CPU key, you will still need a NAND built for your console from Donor files, which I'm assuming you haven't a clue on what to do with that either. Therefore it's even more reason to stop and read.
We will be here to answer any questions you have along the way, but we're not here to hold your hand.
