Hacking Sky3DS error 002-0123

"You can't use this cartridge for onine services"

I'm using the header from a game I dumped myself, and I used the "no ban no sky" tool to patch my games.
They work just fine, but somehow with Animal Crossing: New Leaf I get this error.
I've tried with different templates, and even the "Sky Army Knife" tool (which I didn't really understand), and nothing works.
Any idea of how could I solve this?

You need to use SAK to change the chip ID until it works. Try AE for AC:NL.
