Hacking I might have screwed up big time

[the_g]

So my SD card got corrupted while transferring some files bc it got disconnect from my pc in the process. I did everything I could to recover it but no luck so I just formatted it and every time I turn on my 3ds it gives me this error with or without the damn card plugged in. I did make a nand backup before all this but I dont see how that's useful now

Put the latest luma3ds boot.firm on your sdmc root:

You are hardly the first person to lose a 3DS SD card one way or another.

You'll want to follow all the steps at http://3ds.guide/restoring-updating-cfw to ensure that you avoid this particular problem in the future.

I did everything I could to recover it

I hope that includes running standard recovery software like Testdisk or EASUS. It's a bit late now if you didn't.
