3DS not booting after updating?

So basically i have a 3ds xl that I bought online that had pirated games on it, I played a while on it, and then for some stupid reason wanted to update it...and after I did that, it stopped working, It flashes blue ones and then nothing, doesn't even try to open. Hope I didn't brick it, It was 4-5 years ago, so I don't know what version of luma it had on it.

Most things online say that it is a booting problem, so I bought a new microSD (someone took the old one that was originally there), samsung 64GB and tried to install luma on it with tutorials and such, but it really doesn't work and I can't seem to find a solution? But the card is brand new, doesn't have any folders on it, hopefully it doesn't need the "nintendo3ds" folder for it to start.

I read somewhere that 3ds can't read 64gb cards, could that be the problem? Or is that kind of BS.

I will try to install luma again from zero later, just to check if I really did everything right.

Hopefully there is a solution for this, I'm new to this and this is my first 3ds and I was very excited to have bought it. I just wanna play animal crossing that I bought :( Sorry if my questions sound stupid to someone! If anyone is willing to give some tips thank you!
