title
Installing boot9strap (ntrboot)

{% include toc title="Table of Contents" %}

Required Reading

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

What You Need

  • A magnet that triggers the sleep mode of your device (if using a folding style device)
  • Your ntrboot flashed flashcart
  • The latest release of SafeB9SInstaller
  • The latest release of boot9strap (standard boot9strap; not the devkit file, not the ntr file)
  • The latest release of Luma3DS

Instructions

Section I - Prep Work

  1. Power off your device
  2. Insert your device's SD card into your computer
  • This is the SD card from your 3DS, not the SD card from your flashcart

  1. Copy SafeB9SInstaller.firm to the root of your SD card and rename it to boot.firm

  2. Copy boot.3dsx from the Luma3DS .zip to the root of your SD card

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

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

    ![]({{ "/images/screenshots/boot9strap-ntrboot-file-layout.png" | absolute_url }}) {: .notice--info}

  5. Reinsert your SD card into your device

  6. Power on your device

Section II - ntrboot

  1. Use the magnet to find the spot on your device where the sleep sensor is triggered
  • This step is not needed on the old 2DS (which has a sleep mode switch)
  1. Power off your device
  2. Insert your flashcart into your device
  3. Place the magnet on your device to trigger the sleep sensor
  • On old 2DS, you should instead enable the sleep mode switch
  1. Hold (Start) + (Select) + (X) + (Power) for several seconds, then release the buttons
  • It may take a few attempts to get this to work because the positioning is awkward
  1. If the exploit was successful, you will have booted into SafeB9SInstaller

Section III - Installing boot9strap

  1. Wait for all safety checks to complete
  2. Remove the magnet from your device
  • On old 2DS, you should instead disable the sleep mode switch
  1. When prompted, input the key combo given to install boot9strap
  2. Once it has completed, force your device to power off by holding down the power button
  • Your device will only boot to the SafeB9SInstaller screen until the next section is completed

Section IV - Configuring Luma3DS

  1. Insert your SD card into your computer
  2. Delete boot.firm from the root of your SD card
  3. Copy boot.firm from the Luma3DS .zip to the root of your SD card
  4. Reinsert your SD card into your device
  5. Power on your device
  6. Your device should have booted into the Luma3DS configuration menu
  1. Use the (A) button and the D-Pad to turn on the following:
  • "Show NAND or user string in System Settings"
  1. Press (Start) to save and reboot
  • If you get an error, just continue the next page

Continue to Finalizing Setup

{: .notice--primary}

The following is an optional section that will allow you to restore your flashcart to its original state (to allow it to be used for its standard functions).

Note that the Acekard 2i retains its ability to launch .nds files while having the ntrboot exploit installed. This only applies when the Acekard 2i is in an NDS or custom firmware 3DS! While the ntrboot exploit is installed to the Acekard 2i, it will be unable to launch .nds files on DSi or stock 3DS systems.

Do not follow this section until you have completed the rest of the instructions on this page.

Section V - Removing ntrboot

What You Need
  • The latest release of ntrboot_flasher
  • The flashrom backup corresponding to your flashcart
    • Note that if you followed Flashing ntrboot (3DS Multi System), the flashrom backup already exists in the correct location and does not need to be downloaded
    • Note that if you followed Flashing ntrboot (3DS Single System) or Flashing ntrboot (NDS), the flashrom backup already exists on your flashcart's SD card and should be copied to the location specified below
    • If you do not know which HW revision you have, just try each for your cart of them. Only the correct one will allow your flashcart to launch properly from home menu, but flashing the wrong one will not brick the cart
