Bricked 3ds pls help :(?
If you accidentally deleted the boot file, then that's it. There's nothing you can do except to buy a new one. Sorry for your loss.

Yep. That's the risk you take you when you mod your consoles. I can't really help you since I don't have a 3DS, so you're going to have to look on forums that specialize in this kind of modding. Though if you really bricked your 3DS, then it can't be fixed.
