5220 default root password?

While working with support last week, we "elevated" out of the clish. We then disabled the clish, I do not recall the directory of which we altered the file to disable the clish.

Now, I can only login as admin but cannot search to locate the altered file/directory because of permissions, nor can I 'su' to root due to invalid password. I have searched the admin guide but only it only provides the admin password.
