This is a hacking guide for every 3DS model that has firmware version 9.0.0 - 11.3.0. Do not attempt if your version is above or below that firmware version. This guide is for 3DS's that have never been modded before. This guide used the New Nintendo 3DS XL which using a micro sd card. You may have to use a standard SD card depending on what model 3DS or 2DS you have.
Hardware you need:
1) Large capacity SD or Micro SD card (32GB-128GB)
2) SD Card to USB adapter - I used this one as it is SD and Micro SD although the micro sd slot never worked, I had to use the SD adapter which it does not come with.
