A: first off, you really need to learn what youre doing. you do not downgrade the slim. you can only install custom firmware on it. so if he used that mem stick to downgrade his fat to 1.50, youll have to remake it to install a custom firmware you can remake it by using my guide http://www.zshare.net/download/5554099c2452a4/ skip through the battery part because youve already done it.
