Well a year or two ago, I tried helping my friend modding his Wii. It got bricked during a downgrade. So I gave him my wii since I have a Xbox 360 anyways. Recently the disc tray stopped working and he doesn't use it any more, so I am getting it back. So now I need to know what to do to keep it up to date. I have a 320gb harddrive coming tomorrow( never used a harddrive before and i'm excited ). The wii is either 3.2 or 3.3 U I believe. I modded it using the twilight hack. So all I have to do is get Modmii and it will upgrade my wii to 4.1, give me the newest ios,cIOS(rev21d2x i think), and USNEEK ( not completely sure what this is, but I think it uses the harddrive as the nand)? When using ModMii, do I rehack it or should I not? How do I keep my wii safe through all of this; Bootmii (plz explain how this works since i'm not sure)? I know the wii was able to play CoD: Black Ops and Monster Hunter Tri when he had it.
