Step two

Once you have updated Luma CFW the console should reboot and a menu should open up scroll down to "show NAND or user string in System Settings" and press A then START.

Finally go to system settings once the 3DS boots and perform a system update by going into System Settings > Other Settings > Page 4 > System Update

agree to the terms and conditions and update like you normally would when the update finishes the console should reboot and you will then be on the latest version.
