Then make sure your sd card is formatted in fat32 and not in exfat cause that will be the issue then. You can also do an exfat update btw without updating your system but it's a long painful guide.Reading in the guide is saying that I should make sure my switch has the exfat update present. In my case I did not install the exfat update that the switch prompts. That my be the issue. I just hope if I do that it does not upgrade my switch past 4.1 I have it in airplane mode anyways
