3DS:MSET9 fresh

Required Reading

If you are experiencing the "System Settings loading infinitely after reinserting the SD card" error when trying to install MSET9 using the MSET9 Play Store guide, this page will help you resolve that issue by swapping to a spare SD card. If you are following the MSET9 CLI guide, you should follow the normal troubleshooting steps instead.

All of your original games and saves will be kept intact if you follow the steps properly.

Before starting this guide, please ensure the following two things:

1. You have chosen the correct model type (New vs. Old) and system version in the MSET9 setup.
   • New models have four shoulder buttons (L+ZL+ZR+R) and the C-Stick directly above the Y button - Old models have two shoulder buttons (L+R) and no C-Stick.
2. You injected MSET9 in Section II Step 10, not any earlier.
   • If System Settings is stuck because you injected too early (such as in Section II Step 5), just follow the instructions for removing MSET9 and then restart from the beginning of Section II. You do not have to swap out or reformat your SD card in this case.

Instructions

Follow these steps first to remove MSET9:

1. Power off your console
   • If the console is infinitely loading on the extra data screen, forcibly power it off by holding down the power button for 15 seconds
2. Insert your SD card into your phone/tablet/computer
3. Run the MSET9 Installer application
4. If Remove MSET9 is not highlighted:
   • Tap on Select "Nintendo 3DS" Folder, then navigate to sd:/Nintendo 3DS folder on your SD card
   • Once inside the Nintendo 3DS folder, tap on Use this folder, then Allow if asked
5. Tap Remove MSET9
6. Proceed to the next section

Android phones and Chromebooks cannot format SDs correctly. As such, this method only works if you have a spare SD card that is already formatted to FAT32. Tip: All SD cards that are 32GB or smaller are FAT32 by default.

Play Store

1. Eject the original SD card from your phone/tablet/computer
2. Put the original SD card away.
   

   Do not use the original SD card at all until after CFW is installed, or else the error is likely to keep happening.

3. Insert your spare SD card into your phone/tablet/computer
4. Make sure that this SD card is the spare and not the original
5. Delete everything from the SD card
   

   Do not copy your data back to the spare SD card until after CFW is installed, or else the error is likely to keep happening.

6. Insert the blank spare SD card into your console
7. Return to Section I Step 1 of the MSET9 Play Store Guide and complete every step until the bottom of the page
8. After Luma3DS installs and your console boots to the HOME Menu, power off the console and switch to your original SD card before continuing to Finalizing Setup
