Cisco switch web gui broke after update. How to address this?

[zerophase]

I just updated to the recommended IOS version from the downloads page, and now I can't interact with the web UI. I installed IOS version 15.2.2E9(MD), which was the suggested release on the downloads page. It's the universal install with web based dev mgr. I can login and see the status of stuff, but can't navigate to other pages for configuration. I let the upgrade process finish, and closed the page after it completed to start a new web session as told to do. I even rebooted the computer. Is there any means of rolling this back to an older release? What is the latest release known to work with WS-C2960CG-8TC-L?

And the solution is return the switch. I don't think this thing is secure at all.
