Section I - CFW Check

  1. Power off your device

  3. Power on your device while still holding the (Select) button
  4. If you do not see an unusual menu (e.g. “Luma3DS Configuration”), you may proceed to the next section

If you see an unusual menu, STOP - you already have custom firmware! Continue from here.

Section II - System Version Check

  1. Open the System Settings application
  2. Your system version will be displayed on the bottom right of the top screen (e.g. “Ver. 11.17.0-50U”)

To find the correct method for your device, please enter the system version you found in Section II.
