If I were you, instead of installing all that crap on my phone, I'd download PuTTY, a windows SSH client. Use it to login as root/alpine (btw, you should change that password). browse to the Themes folder (cd /Library/Themes) and see what happens. If you can't get in, tell us what the error is, and do an ls -ld /Library/Themes and we can see if something is screwy.
