You can't get access to homebrew on 4.3 firmware (needs to be 9.0 or above). You can install homebrew programs to your home menu but it would be easier to just get B9S.
They will assess it and medicate as necessary but in all cases it is better to take action before it becomes a problem and to stave things off from becoming a problem in the first place
