This is an add-on section to check if your console already has a modern custom firmware.

If your console already has an arm9loaderhax or boot9strap based custom firmware, you will need to follow the instructions indicated to upgrade your setup to a modern one.

If your console has a menuhax based CFW setup, you should clear Home Menu’s extdata, then follow all instructions on your SysNAND.


  1. Turn off your console
  2. Hold the (Select) button
  3. Turn on your console while still holding the (Select) button
  4. You should now see a configuration menu of some sort

If your console boots to the normal home menu, return to Get Started

If you see a Luma3DS version of 7.0.5 or lower, continue to A9LH to B9S

If you see a Luma3DS version of 7.1, continue to Updating B9S

If you see a Luma3DS version of 8.0 or greater, continue to Restoring CFW

If you see something not described by the above options, join Nintendo Homebrew on Discord and ask, in English, for help.
