Required Reading

This page is for existing arm9loaderhax users to update their devices 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.

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

To extract the .7z files linked on this page, you will need a file archiver like 7-Zip or The Unarchiver.

If you have a PIN enabled on Luma3DS, SafeB9SInstaller will give you an “OTP Crypto Fail” error unless you temporarily disable your PIN (you can re-enable the PIN after the update).

There have been reports of a wave of bans being handed out to CFW users by Nintendo. To protect yourself, please do the following steps before starting this guide:

  1. Go to System Settings, then “Internet Settings”, then “SpotPass”, then “Sending of System Information”
  2. Disable the “Sending of System Information” option
  3. Exit the System Settings
  4. Go to your Friend List (the orange Face Icon in the top row of your Home Menu)
    • If you receive an error and are kicked out of the menu, the Friend List setting is either already disabled or your console cannot connect to Nintendo’s servers (due to a ban or connection issues)
  5. Go to the Friend List settings, then “Friend Notification Settings”, then “Show friends what you’re playing”
  6. Disable the “Show friends what you’re playing” option
  7. Exit your Friend List

What You Need

Note that the following required file named secret_sector.bin is the same one that was found in the various data_input.zip file versions. If you already have that file on your disk somewhere, you can use that one instead of downloading the one below.

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.

You can now use Luma3DS Updater to update your Luma3DS to the latest version just by opening it and pressing (A).

This is not the same thing as a System Update; it just downloads and extracts the newest Luma3DS files.

This will only update the Luma3DS files on your SD card. If you boot your device without an SD card, it will use the version you placed in CTRNAND.

You will now boot Luma3DS CFW SysNAND by default.

You can now hold (Select) on boot to launch the Luma3DS configuration menu.

You can now hold (Start) on boot to launch the Luma3DS chainloader menu (note that the Luma3DS chainloader menu is only displayed if there is more than one payload detected).

You can now hold (Start) + (Select) + (X) on boot to dump the ARM11 bootrom (boot11.bin), the ARM9 bootrom (boot9.bin), and your console unique OTP (OTP.bin) to the /boot9strap/ folder on your SD card (note that this will not have any kind of prompt or message).

You can now press (L) + (Down) + (Select) while the system is booted to open the Rosalina menu integrated into Luma3DS. For a full list of Rosalina features, please see the Luma3DS v8.0 Release

If you would like to upgrade to a bigger sized SD card, all you have to do is format your new SD card as FAT32 and copy paste the contents of the old SD card onto the new SD card.

If your new SD card is bigger than 32GB, then you have to use a different tool to format it, such as guiformat for Windows, gparted for Linux, or Disk Utility for Mac.

To use NTR CFW, install BootNTR Selector.
