I was working great until I decided to update the phone since I recieved the message for an update. I unfroze everything but didn't unroot. After the install I opened up titanium backup and wanted to freeze aps, but it wouldn't work because I wasn't rooted. I opened terminal emulator and typed "su" and got a "permission denied". I still appear rooted and still have the .apk and other root files still on the phone along with the superuser icon. I tried rooting again but kept getting error messages saying I am denied in the terminal emulator commands.. Suggestions?
