This section will reset your system settings to its defaults. Installed games and their save data will not be affected. This is required to prevent known issues relating to extended memory mode and applets on some consoles.

::: warning

This process will reset your Mii data. If you wish to save any Miis that you have created, either generate a QR code for each Mii that you want to save, or make a backup of SYSNAND CTRNAND:/data/<ID0>/extdata/00048000/f000000b before following these instructions. You can restore this file to the same directory after your console has gone through initial setup.
