I want to completely wipe my phone of anything unnecessary. I've copied everything to a temporary directory on my computer just as backup. Can I just delete everything I see on the SD card, then flash it? I guess the more important question would be this: if I delete everything on the sd card, will it even allow me to unmount it and boot into the bootloader to use rsd? Or are their key pieces on the sd card that would screw everything up?
Basically, I've switched ROMs so many times over the past few weeks, as well as oc kernels, wifi kernels, apks, regular apps, etc, I've pretty much figured out exactly how I want my phone to be customized, but want to get rid of all the crap I don't need on it... in case you're wondering why I'm wanting to do it. I know it might not be necessary, but still.
