Homebrew Power Issue with a N3ds

[K3ebl3r]

So I was updating a N3ds with sighax to boot9 following the 3ds.guide page, and my chainloader wouldnt boot at all. After a few attempts at verifying the sd card and all of that my 3ds wont even turn on now.
I was trying to update luma and boot9 to latest version and somehow it doesnt let me turn on my ds now.

Ive tried booting w/o sd card and flash card and it doesnt turn on now. the blue light (power) turns on for a second then turns right off. Any ideas as to why?

Make sure you have boot.firm from Luma on the root of your SD card. If 8.0 doesn't work then try 7.1, and vice versa.

Thanks so MUCH! 7.1 worked for me.

EDIT: Fixed everything i needed to. Thanks for everything
