I install successfully a9lh in my normal n3ds, now I have my n3ds zelda edition and I wanted to do the same, BUT while I was downgrading my device some days ago from 9.9 to 9.2 I got an error, I freaked out and then I read that I should remove the micro sd and then boot again, so yeah, after that, I am afraid to continue, by the way right now I installed menuhax, I think last version because there is no color flashing at boot, then Installed Luma, now that Plailect updated his guide should I continue?, is downgrading to 2.1 still mandatory?, afaik there is no problem if I use a 64gb microsd isn't?
