So, I was installing Luma and A9LH on my friends o3ds that was 9.20 with cakes installed. Somewhere along the lines I accidentally deleted everything on the SD card. Now it won't boot with or without the SD card. With the SD: Black screen. Without the SD: The power light turns on for a second then off. I read this http://gbatemp.net/threads/help-is-needed-3ds-not-booting-without-sd-card.438867/ thread trying to fix it cause he has a similar problem but to no avail... Help?
