Here's a video of how I'm doing it. I have the AR DSi in the back, and I'm making sure to press all of the buttons. the back of the flashlight is a magnet. Ive tested it on my other consoles and it's easily capable of triggering sleep mode on them.
EDIT: I've even tried placing multiple magnets all over the console. It will never load into anything besides blue screen:
It seems like you're doing it correctly. Are you using the ARDSi with the sd slot?
Another important thing to note since you have the original 3DS: Try placing the magnet on the 3ds and turning it on without the button combo. If you placed the magnet correctly, the 3ds should not turn on. If it turns on with the magnet on it, you are probably not triggering sleep mode.
