ROM Hack 3ds won't boot even without sd card

[KyskeBenkou]

Basically a year ago i attempted to hack my 3ds and gave up Midway through, tried to retry but the 3ds will give a faint blue light then fade off, i think i have all cfw files on the sd card with boot.firm any solution would be appreciated

An screenshot could be helpfull or a video, if the console make a sound and turns off that could be display issue, if you updated to 11.15 you must have boot9strap 1.3 or fastboot 1.2 both with luma 10.2.1, Im not english speaker but is enough you understand what I said
