Ok, I've been rooted for a while now but want to delve into the darkside of custom ROM's (mainly CM7). Everybody says to make sure to to do a "Nandroid" back-up... I don't understand? Maybe I'm just not comprehending, or I'm just an idiot and can't find it via the search function, but I I can't figure out what to do! Is it an App I need to download? Any help, or direction to any links that would help will be greatly appreciated...
