Installing boot9strap (Hardmod)
Technical Details (optional)
An excellent guide to getting a hardmod can be found here.
This is a currently working implementation of the “FIRM partitions known-plaintext” exploit detailed here.
Using a hardmod, we can dump the NAND image, install custom firmware to the NAND image, then re-install the hacked NAND image to the console.
Compatibility Notes
To use the magnet links on this page, you will need a torrent client like qBittorrent or Deluge.
To extract the .7z
files linked on this page, you will need a file archiver like 7-Zip or The Unarchiver.
This will work on New 3DS, New 2DS, Old 3DS, and Old 2DS on all versions that you have a corresponding .firm
for.
