Disable or Uninstall To Change domain name

I am looking for a way to uninstall or disable Joomdle and not be locked out of moodle after doing so. I have tried 20 ways and I keep getting locked out of moodle and have to perform a restore of the site to get back in. I am Using Joomla 3.4 and Moodle 2.9 any words of wisdom would be greatly appreciated. I need to do this to change the domain name and then put it all back in place.

You should be fine if you create a moodle admin with auth type "manual".

We always recommend that you keep a normal (auth=manual) admin user so you can always log in to Moodle if something breaks with Joomdle.
