Error in Boltzman brains theory is that he assumes that universe with brains randomly fluctuated into existance into its current form , and concludes that this form is more complex than just brain and therefore brains without environments are more common (maybe iPhones or Bible are even more common then), and assumes that brain can exist without environment. also second law of thermodynamics states that resulting entropy would never be decreased. and doesnt tells us about entrophy dynamics in intermediate steps.
