Am I rooted or not?

view story

http://androidforums.com – I installed stock OTA JB a couple of days ago and lost root access. I tried using Voodoo to restore root but that failed. Finally I used Wugs tool and it seemed to be successful. Titanium Backup is working as rooted as so do a couple of other root apps. I just installed Barnicle, and when I went to run it, it indicated that I was not rooted. Barnicle's help section told me to install Terminal Emulator and type in su -c-id which I did and it came back as "access denied". So, it seems that I'm not rooted. However, Titanium Backup is running, so I'm confused. Thanks in advanc (General)
