I accidentally did a "simple nandroid backup" instead of an "advanced nandroid backup" before my most recent rom flash. I want to go back to the rom I was using before. I did some research to find out what "simple nandroid" actually backed up and found this thread that says a simple backup only does /boot, /data, and /system. It does not include /cache, /misc, and /recovery. Is it worth it for me to do a nandroid recovery, or should I just re-flash the previous rom? What all will I be missing without the /cache, /misc, and /recovery backups?
