OP Basicly what wormdood said but i'd advise down the line, getting a cheap extra of a supported card for NTRBoot incase your left w/ a Brick that makes it hard w/o one to recover from. th eonly brick it cant solve is an MCU Brick but since past a certain FW version is Damn stupid hard to brick in that manner.Installing boot9strap (ntrboot) - 3DS Guide you want the last section of this page

I had to test this multiple times for different CFWs. I can safely say that NTRBoot was able to recover every single issue I encountered from downgradingHas anyone tried that before?
