You were quick to give another member who is trying to help a basic slap in the face. No where has he said that the flasher will allow you to get 3.7x CFW, he suggested 2 ways of being able to play newer games on 3.55.
Your statement "It allows you to downgrade from 3.7x to whichever firmware you want on your console....." is specifically incorrect as it allow downgrade to a special firmware and then to a custom firmware of the users choose. Furthermore if you wanted to be soo specific you didn't mention how much of a pain it is to do.
If you are going to promote TB at least do it right!!!, or better yet DON'T!!!
