    I'm downgrading my system and being a first time Gateway user here... how do I do the exploit? I have the blue card, but I don't know what to do next.

    If you're on 4.5, put the blue card files on the microSD card, put that card in the blue card and boot it on your DS. Scroll down to find the Installer and run it. Then exit the card, go to the system settings > Profile > Nintendo DS Profile and you should be booted in GW mode.

    If you're on a later firmware, use the web exploit, and don't use the blue card.
