DO NOT USE VIDEO GUIDES, please use the guide on the site and read it SLOWLY, can you go into recovery mode? (L+R +DOWN+A)

If it's turning on and then off (the light), you're missing boot.firm in the SD's root.

(Replace current with a new one) You can grab a boot.firm at https://github.com/AuroraWright/Luma3DS/releases.

dude can you stop making threads about the same thing and stop following video guides.

use this https://3ds.hacks.guide/

Video tutorials are generally not kept up to date. So you'll have downloaded the latest files, but using old methods. This will produce bad results. Written guides, particularly the https://3ds.hacks.guide/ , update their guides to reflect the current files and process. If following a video messed things up, any update could be the issue, be it the official or homebrew stuff, so it'll be really difficult to narrow it down. This is why folks will repeatedly say to just follow the written guide instead. This way it's easy to figure out what exactly what went wrong.

Was anything updated on the console recently? Will it get past that screen at all?
