Upgrade from 5.3.0.2443 to 5.3.1.2505 fail (locked out)

Yesterday I attempted to update to 5.3.1.2505 and it seems to have halfway bricked my installation.

When I try to go to the URL of the OMIVV box, I am prompted for password. I enter the password I have documented, and I'm given the invalid credentials error.

I go to the console of the VM, and I'm able to login as admin with the same credentials. When I try "Change Admin Password" it sells me "Entered current password is incorrect. Please try again".

I'm not sure what to do next....

Is there a way to recover or force the password to reset via command line / putty?
