Required Reading

This is an add-on section for moving the contents of a previous EmuNAND to your new SysNAND CFW, then removing the old EmuNAND partition. Note that the terms EmuNAND and RedNAND refer to slightly different implementations of the same concept.

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 and the (A) button to select “GodMode9” for these instructions.

You MUST have already installed Luma3DS and boot9strap to use this.

What You Need

  • An existing EmuNAND
  • The latest release of GodMode9 (the GodMode9 .zip file)

Instructions

Section I - Prep Work

  2. Insert your SD card into your computer
  3. Copy GodMode9.firm from the GodMode9 .zip to the /luma/payloads/ folder on your SD card
  4. Copy the gm9 folder from the GodMode9 .zip to the root of your SD card
  5. Reinsert your SD card into your console
