Just copying the RecoveryFS to the RootFS partition won't work. The recovery works by formatting the RootFS, unpacking a file onto it and also rewriting boot images. The commands in the link are only part of what you need.
You should have been able to recover from this by doing a factory reset using the buttons. But, it might be to late. I'll PM you a link to an SD card image that you can use to create a new card. That should get you going.
