An excellent guide to getting a hardmod can be found here. If you are on a New 3DS, read this and this before hardmodding.

This is a currently working implementation of the “FIRM partitions known-plaintext” exploit detailed here.

To use the magnet links on this page, you will need a torrent client like Deluge.

This will work on New 3DS, New 2DS, Old 3DS, and Old 2DS on all versions that you have a corresponding .firm for.

What you need

  • Your NAND image extracted using your hardmod
  • The latest release of boot9strap (standard boot9strap; not the devkit file, not the ntr file)
  • The latest version of hardmod-b9s-installer
    • Windows users can use the compiled .exe, while Mac and Linux users will need to have Python 3 installed to run the .py
  • The latest release of Luma3DS (the .7z file)
  • The latest release of the Homebrew Launcher
  • The .firm corresponding to your device and version:
