Hello. I have seen many posts about how people have accidentally updated their sysnand rather than their emunand. 1. Setup folders on your sysnand home screen to spell out the word SYSNAND. //each folder can have 1 main letter, which will appear as it's title. it should look like this S[Y]S[N][A][N][D] or S[Y]S [N][A][N][D] if you use multiple rows 2. use a distinctive theme to distinguish emunand and sysnand. //you can buy a theme from eshop or download it online and use gateway for it since you're not going to be using sysnand much, you shouldn't even bother giving it a theme unless it's very distinctive. i use the default home menu for my sysNand and the smash bros theme for the emunand. if you think your on sysnand, just check your home menu for the sysnand folder letters or the theme. i hope this guide helps!
