I was able to unmount it and I tried the sudo command. It worked, but still wouldn't let me do what I wanted. It keeps saying the the file or directory does not exist. I have tried everything I can think of. Is there any reason why it would say this (other than, you know, if the file doesn't exist)? This is what I typed in (after I unmounted it): sudo dd if=/Users/NOOK/Desktop/Team-B-CM7SD-alpha_final.img if=/dev/disk1s1
NOOK is the name of my SD Card and Team B... is the name of the img thing. disk1s1 is what came up when I used the mount command at the beginning. Looking at this, do you have any idea what I'm doing wrong?
