After clicking ''Install normal version'' to upgrade Luma from 6.6 to 7.0, do you have to do anything else? And if so, how do you do it? I have been reading that you have to do something with the sysnand but I have no idea what to do and I'm scared of touching anything, and well, I followed the 3ds guide if that helps. Thank you. Edit: And after all that, is it safe to upgrade to 11.4?
