=== Using GodMode9 ===
This is the default setup when using [https://3ds.hacks.guide/ 3DS Hacks Guide]. This does not work when using boot9strap through ntrboot. If ntrboot is used, use the GodMode9 section below.
This requires GodMode9 v1.1.8 or newer, started through boot9strap.


#While holding START + SELECT + X, press POWER.
#Start GodMode9.
#Check for {{code|/boot9strap}} on the SD card. The files {{code|boot9.bin}} and {{code|otp.bin}} should be created inside.
#Navigate to {{code|[M:] MEMORY VIRTUAL}}.
#Press L on {{code|boot9.bin}} and {{code|otp.mem}} to select both.
#Press A to select, then choose "Copy to 0:/gm9/out".
#Turn off the system.
#Check inside {{code|/gm9/out}} on the SD card. The files {{code|boot9.bin}} and {{code|otp.bin}} should be created.
