Office 365 2013 public website favicon

I've spent most of the day trying to implement a bespoke favicon for Office 365 public website. Just some of the solutions yet all appear to break site links. The only way to return the site is to revert back to previous configuration.

Is there a solution that actually works? If so detailed illustrated step by step details are required. Thank you.
