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](https://github.com/AuroraWright/).
{: .notice}

This will install [AuroraWright's Fork](https://github.com/AuroraWright/arm9loaderhax) 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.

**You cannot use another console's OTP or you will brick GUARANTEED.**

#### 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 using the Luma3DS chainloader.

In this case, we use Luma3DS by [AuroraWright](https://github.com/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 your CFW installation easily)*
+  **Hourglass9** *(multipurpose tool which can do NAND and cartridge functions)*

3. Go to `http://2xrsa.3ds.guide` on your 3DS
  + If you get the error "This service is not available in your region", use the System Settings to set your device's country to match the NAND region you installed with 2.1.0 ctrtransfer
  + If you get another error, [follow this troubleshooting guide](troubleshooting#ts_browser)
  + If you get a glitched screen, [follow this troubleshooting guide](troubleshooting#ts_safe_a9lh_screen)
  + If you are on a 2DS or New 3DS and Wireless Communication is off, you can re-enable the wireless by removing the battery and unplugging the charger for several seconds then booting back up
4. Press (Select) to Full Install
5. The installer will now install arm9loaderhax on your device (this is very fast)
6. Shut down your console by pressing any button
7. 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

##### Section III - Configuring Luma3DS

1. Boot your device while holding (Select) to enter the Luma3DS configuration menu
  + Make sure to start holding the button before pressing power
  + If you get a black screen, [follow this troubleshooting guide](troubleshooting#ts_sys_a9lh)

2. Use the (A) button and the D-Pad to turn on the following:    
  + **"Autoboot SysNAND"**
  + **"Use SysNAND FIRM if booting with R"**
  + **"Show NAND or user string in System Settings"**
3. If you are using a **New 3DS**, you can *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
4. Press (Start) to save and reboot
  + If you get a black screen, just continue to the next section   
  + If you get a "Failed to mount CTRNAND" error, 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](move-emunand) instead of doing the first four steps in this section.
{: .notice--info}

1. Boot your device while holding (Start) to enter Hourglass9
2. Go to "SysNAND Backup/Restore"
3. Go to "SysNAND Restore (keep a9lh)"
4. Input the key combo given, then select the `NANDmin.bin` image when prompted by pressing (A)
5. Press (Start) to reboot
  + If you get a black screen, [follow 9.2.0 ctrtransfer](9.2.0-ctrtransfer)
6. If your backup was of a version between 3.0.0 and 4.5.0, your console will not boot until you manually download the required firmware:
  + Download [this file](http://nus.cdn.c.shop.nintendowifi.net/ccs/download/0004013800000002/00000056) and rename it to `firmware.bin`
  + Download [this file](http://nus.cdn.c.shop.nintendowifi.net/ccs/download/0004013800000002/cetk)
  + Copy `firmware.bin` and `cetk` to the `/luma/` folder on your SD card
  + Delete both of these files after updating your 3DS
7. Update your 3DS by going to System Settings, then "Other Settings", then going all the way to the right and using "System Update"
  + Updates while using A9LH + Luma (what you have) are safe, stop asking about it
  + The warning about never updating a New 3DS from 2.1.0 does not apply after restoring your NAND backup.
  + 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](9.2.0-ctrtransfer)

##### Section V - Injecting FBI

1. Boot your device while holding (Start) to enter Hourglass9
