Then hopefully he haven't burnt a fuse then. But I still recommend waiting. SciresM is on it already and it's probably fixed soon.1.I often use eshop while I am using Atmosphere but I have not got banned yet.So I think it is ok to be logged to eshop while using CFW.
2.You should never install any nsps. If you connect to Nintendo Server after installing nsps,you will get banned soon.

If you are using the latest atmosphere,autorcm will not be replaced even if you update your switch in the official way.
