I had restored back to 10.0.3 and back to normal.(fast boot up and just 1 times)
If I update 10.2 directly from setting-> system, the worst case is get "banned"?
Actually, what will happen on my device, if Nintendo checked and noted I had modified my switch? Unable to boot up? Unable to connect Nintendo network? Or disable my device connect any network?
I had updated 10.0.3 to 10.2, seems if I use the "while rabbit NX" App to upgrade my switch, itwill caused the long booting problems.
Thanks
