Installing arm9loaderhax /installing-arm9loaderhax.html

The final Step of this guide is to install arm9loaderhax and setup Luma3DS to run just milliseconds into the boot. This is accomplished by using SafeA9LHInstaller by AuroraWright. {: .notice}

This will install AuroraWright's Fork of arm9loaderhax. {: .notice--info}

We will also setup the ability to launch payloads from arm9loaderhax, giving us the ability to unbrick our SysNAND from situations that would normally brick us by restoring from backup. {: .notice--info}

You cannot use another console's OTP or you will brick GUARANTEED. {: .notice--danger}

Overview of steps

In this section, we will go through the process that all the other steps have led up to: actually installing arm9loaderhax.

This is nearly the best possible kind of device exploit because it is permanently installable into the NAND firm partitions, and runs before most of the OS loads, allowing it to not only work on all versions once installed, but also protect itself and recover from most situations that would brick a non-A9LH 3DS such as a nonfunctional home menu or bad title install.

The file arm9loaderhax.bin is what is launched by arm9loaderhax itself after it finishes loading off of NAND, and can be any valid arm9 payload. This file can be replaced at any time, although Luma3DS allows for the launch of other arm9 payloads by holding buttons on boot.

In this case, we use Luma3DS by AuroraWright to boot a patched SysNAND directly, allowing us to completely bypass the need for any kind of EmuNAND, vastly simplifying the usage of a hacked 3DS in addition to saving SD card space.

Once arm9loaderhax is installed and Luma3DS is setup with the correct options, we then restore our previous backup.

During this process, we also setup programs such as the following:

  • FBI (installs CIA formatted games and applications)
  • Luma3DS Updater (updates our CFW installation easily)
  • Hourglass9 (multipurpose tool which can do NAND and cartridge functions)

What you need

Instructions

Section I - Prep work

{% capture notice-5 %} Ensure you are using an SD card that is not corrupted!

If you use a corrupted SD card without fixing it, you may BRICK!

If you think your SD card may be corrupted, check your SD card for errors using H2testw (Windows), F3 (Linux), or F3X (Mac)! {% endcapture %}

{{ notice-5 | markdownify }}
  1. If it exists, copy the /files9/ folder on your SD card to a safe location on your computer and back it up to multiple locations (such as online file storage); the files inside could save you from total data loss if you break your system
  2. Create a folder named cias on the root of your SD card if it does not already exist
  3. Delete the a9lh folder from the root of your SD card if it exists
  • If you accidentally install arm9loaderhax using another device's OTP.bin, you will BRICK!
  1. Delete the 3ds folder from the root of your SD card if it exists
  2. Copy the contents of the starter.zip to the root of your SD card
  • This will include a brand new 3ds folder to replace the one you just deleted
  1. Copy the contents of the SafeA9LHInstaller zip to the root of your SD card
  2. Copy the a9lh folder from data_input_v3.zip to the root of your SD Card

Section II - Installing arm9loaderhax
  1. Reinsert your SD card into your 3DS
  2. Do the steps for installing arm9loaderhax on your device:
  • Old 3DS
    • You should be on 2.1.0
    • Go to http://dukesrg.github.io/2xrsa.html?arm11.bin on your 3DS
    • Press (Select) to Full Install
    • The installer will now install arm9loaderhax on your device (this is very fast)
    • Shut down your console, hold the power button until it turns off if necessary
    • Copy your console specific OTP.bin from the /a9lh/ folder on your SD card to a safe location on your computer and back it up to multiple locations (such as online file storage), then reinsert your SD card into your 3DS
  • New 3DS
    • Get into the homebrew launcher through the entrypoint of your choice
    • Launch SafeA9LHInstaller
    • Press (Select) to Full Install
    • The installer will now install arm9loaderhax on your device (this is very fast)
    • Shut down your console, hold the power button until it turns off if necessary
Section III - Configuring Luma3DS
  1. Hold select on boot to enter the Luma3DS menu
  1. Use the (A) button and the D-Pad to turn on the following:
  • "Autoboot SysNAND"
  • "Use SysNAND FIRM if booting with R (A9LH)"
  • "Show NAND or user string in System Settings"
  1. If you are using a New 3DS, you should also enable the following:
  • "New 3DS CPU" to "Clock+L2(x)"
    • This will increase the framerate of many games, but may cause instability in others
    • If some games do not work properly, disable this option and try again
  1. Press Start to save and reboot
  • If you get a black screen, just continue to the next section
Section IV - Restoring the System

If, before following this guide, you already had an EmuNAND setup and would like to move the contents of your previous EmuNAND to your new SysNAND CFW, now is the time to follow Move EmuNAND instead of doing the first step in this section. {: .notice--info}

  1. If you are an Old 3DS or 2DS user who has done 2.1.0 ctrtransfer, do the following:
  • Copy NANDmin.bin to the /files9/ folder on your SD card
  • Open Hourglass9 from arm9loaderhax by holding (Start) on boot
  • Go to "SysNAND Backup/Restore"
  • Restore from NANDmin.bin
  • Press (Start) to reboot
  1. If your backup is of a version between 3.0.0 and 4.5.0, do the following
  • Download Luma 3DS v6.3.1
  • Copy arm9loaderhax.bin from the Luma3DS v6.3.1 zip to the root of your SD card, overwrite existing files
  • Download this file and rename it to firmware.bin

  • Copy firmware.bin and cetk to the /luma/ folder on your SD card
  • Delete both of these files after updating your 3DS
  • Replace the old v6.3.1 Luma3DS arm9loaderhax.bin with the latest version after updating your 3DS
  1. Update your 3DS again by going to System Settings, then "Other Settings", then going all the way to the right and using "System Update"
  • Yes this is safe, stop asking about it.
  • If this gives you an error, set your DNS settings to "auto"
  • If this still gives you an error and your NAND is below 9.2.0, follow 9.2.0 ctrtransfer
Section V - Injecting FBI

{% capture notice-10 %} 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. Luma3DS Updater only updates the files located on the SD card.
This will only update the Luma3DS files on the SD Card. If you boot the device without an SD card, it will use whatever version you placed in CTR NAND.

{{ notice-10 | markdownify }}

{% capture notice-6 %}
You will now boot a Custom Firmware based 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 Hourglass9, an arm9loaderhax safe multipurpose NAND and cartridge tool.

You can remove your NAND backups from /files9/ as long as you still have them backed up to a safe location. {: .notice--info}

{% capture notice-7 %} You can remove any extra files and folders from the root of the SD card that are not in the following list:

Files and folders to keep on your SD card:
