Ok, I've tried searching and reading about nandroid backup/recovery and such, but it's made me more confused. What is nandroid? How and where do I get it? I have an Optimus M with Android 2.2 rooted with z4Root. I haven't done any modifications such as flashing a new rom, or anything else. Just rooted and installed an app so I could wifi hot spot. I have since removed the app. My phone is still rooted though, just haven't really done anything with it. I'm interested in custom roms, but I don't know where to look for 'em. Everything I read says to make sure you've got a nandroid back up. I found something that says it comes with something called clockwork, but I'm not sure what that is. I see a lot of threads about roms for 2.2.1, but my phone is 2.2. I wouldn't mind a rom for 2.3 or what ever the newer version is. Anyway, thanks for any info you can give me to help clear up my confusion.
