3DS:MSET9 fresh

This page is for resolving the "System Settings loading infinitely after reinserting the SD card" error when trying to install MSET9. It also works if you aren't getting the Mii Maker entry at the Extra Data screen.

The steps below hashes are a more detailed run through of the troubleshooting steps located here and will perform a fresh install with either a spare SD card, or your original SD card which has been backed up and formatted, to avoid issues with your current install causing MSET9 to not work properly.

Before continuing please ensure you are choosing the right model (old 3DS, old 3DS XL, old 2DS vs New 3DS, New 3DS XL, New 2DS XL) and correct system version.

Also please make sure you are installing/injecting AFTER ejecting from the extra data screen and not before.
