Required Reading
This page installs an 11.15.0 CTRTransfer image to your device to recover its system software.
Note that if you have any payload files other than GodMode9.firm in the /luma/payloads/ folder on your SD card, holding Start on boot will display a “chainloader menu” where you will have to use the D-Pad Up, D-Pad Down, and A buttons to select GodMode9.firm for these instructions.
You cannot do this guide without having installed Luma3DS and boot9strap first. If you have not done so, start from this page.
Performing a CTRTransfer may break extended memory mode games (Monster Hunter, Super Smash Bros, Pokemon Sun/Moon) on Old 3DS/2DS devices. If this occurs, you will need to format the device (using TinyFormat or System Settings) to fix the issue.
