no because the title update is actually a save on the harddrive and if you remove it and try to play it will give you an error and then freeze.
The only way for you to get this achievement w/ the glitch is to remove the title update and your single player save (but that erases everything) beat hard then beat old school and then do the glitch. But in my opinion it isn't worth it since u have to do 2 playthroughs again.
