I have a couple basic questions I'm hoping I can get answered before I start messing around with different ROMs/Radios/Kernels... Before I rooted, when I felt like things were getting cluttered or had an OCD attack, I would do a factory reset. How does that work? What "source" files are used? Is the emmc directory the only directory not "cleaned" in a factory reset? Keep in mind I'm used to my workstation/laptop experience where I would format, then install a clean version of the OS from a CD/DVD and then I would install 3rd party apps and move my data back. Any analogies would help my simple mind! One day I did a factory reset, the decided to root. Everything went perfect. I moved some bloatware to an apps.disabled directory, then did all my customizing again. Now I want to play with different ROMs. I do however want to hedge my bets in case I ever want to go back to where I am today. I've done a clockworkmod backup. Does that essentially copy all the phone storage (except SD Card data) over to the SD Card? If not, what is left behind. Will a clockworkmod wipe erase ALL of the on board phone storage (except the SD Card data)?
