So my cousin has a old 3ds that's in firmware 1.0.0U i wanted to installed a9lh with Luma in it but I never seen a 3ds on 1.0.0 so I don't know how should I go about it? I've installed a9lh on 6 different 3ds so I know what I'm doing i just don't know what I should do since it's on 1.0.0 do i update it somehow or what? I don't want to update it to 11.3.0
