Alright, so I've gone through the forums looking for something like what I have set up... and I don't believe I've found it. So at the risk of sounding nooby here it goes. My Wii is on 4.0U now. Here's a mini-history of what I've done to it. 3.2-3.4 Official update. 3.4-3.2 ARC (I think) then waninkoko's 4.0 safe updater to get to where I am now. I'm looking at using the "Simplistic Guide" but I'm not sure if it'll screw up. I also have cIOSCORP3.5... probably shouldn't. cIOS249rev14, and cIOS222v4. And a custom theme. I'm assuming I'll have to uninstall cIOSCORP, but do I have to do anything else before I attempt to use this guide? Also... I'm still not clear on NAND backups. If I back it up now, will everything be the way it is now if I put it back on, it seems too good to be true? Thanks, and sorry for the noobiness!
