Required Reading

This page is for existing arm9loaderhax users to update their consoles to boot9strap.

All future releases of Luma3DS will only be made in the .firm format, which will only be compatible with boot9strap and sighax. This means that to continue receiving the latest updates of Luma3DS, you should use this page to update your installation.

What You Need

WARNING

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

INFO

Note that, only on New 3DS, secret_sector.bin is needed to revert the arm9loaderhax exploit, which is why it is not needed for the installation of boot9strap on a stock console. If you do not have a New 3DS, you do not need secret_sector.bin.

• - New 3DS Users Only: secret_sector.bin (magnet link)
• The latest release of Luma3DS (the Luma3DS .zip file)
• The v7.0.5 release of Luma3DS (direct download)
• The latest release of SafeB9SInstaller (direct download)
• The latest release of boot9strap (direct download)

   • If the luma or payloads folder doesn't exist, create them
   • Delete any other existing .bin payloads (GodMode9.bin, Decrypt9WIP.bin, Hourglass9.bin, etc.) in the /luma/payloads/ folder on your SD card as they will not be compatible with boot9strap compatible Luma3DS versions

6. Create a folder named boot9strap on the root of your SD card

7. Copy boot9strap.firm and boot9strap.firm.sha from the boot9strap .zip to the /boot9strap/ folder on your SD card

   • If you see the luma configuration screen instead of SafeB9SInstaller, simply press (Start), then shut down your 3DS and try again
   • If this gives you an error, try either using a new SD card or formatting your current SD card (backup existing files first)
2. Wait for all safety checks to complete
   • If you get an "OTP Crypto Fail" error, download - aeskeydb.bin, then put it in the /boot9strap/ folder on your SD card and try again
3. When prompted, input the key combo given on the top screen to install boot9strap
   • If a step on the lower screen has red-colored text, and you are not prompted to input a key combo, follow this troubleshooting guide
