Hacking ninjhax after downgrading

[Rinnegatamante]

Hi, does someone tried to reinstall ninjhax on his retail Cubic Ninja cartridge after downgrading with GW ULTRA 3.01?

I'm trying to boot ninjhax installer through 4.5.0-8E QR Code but it seems it crashes everytime :/

Don't forget to put the boot.3dsx file in root. It will crash if it is not there.
