### Last Update: 3 Nov 2016
|
|
|
|
The actual installation of arm9loaderhax itself consists of payload files installed into the NFIRM partitions on your device's NAND chip, which is soldered to the motherboard itself. These payloads are updated rarely and only really serve the purpose of launching `arm9loaderhax.bin` from the SD Card, which is, in our case, Luma3DS.
|
|
{: .notice}
|
|
|
|
So far, arm9loaderhax itself has only been majorly updated once.
|
|
{: .notice--info}
|
|
|
|
The old version of arm9loaderhax (sometimes referred to as "v1" because it was installed using SafeA9LHInstaller v1) was the latest version of [Delebile's initial implementation](https://github.com/delebile/arm9loaderhax).

|
|
|
|
The new version of arm9loaderhax (sometimes referred to as "v2" because it is installed using SafeA9LHInstaller v2 or FIRM81 because of its use of 8.1's NFIRM files to make room for larger payloads) is the latest version of [AuroraWright's Fork](https://github.com/AuroraWright/arm9loaderhax) of [Delebile's initial implementation](https://github.com/delebile/arm9loaderhax).

|
|
|
|
These steps will also update your various payloads and the AES key database.

#### Instructions
|
|
|
|
**For all of these instructions, OVERWRITE any existing files on your SD card.**
|
|
|
|
##### Section I - Prep work
|
|
|
|
1. Delete any existing `aeskeydb.bin` from the root of your SD card
|
|
4. Delete the `a9lh` folder from the root of your SD card if it exists
|
|
2. Copy `aeskeydb.bin` to the `/files9/` folder on your SD card
|
|
3. Copy `Hourglass9.bin` from the Hourglass9 zip to the `/luma/payloads/` folder on your SD card and rename `Hourglass9.bin` to `start_Hourglass9.bin`
|
|
5. Copy `arm9loaderhax.bin` from the SafeA9LHInstaller zip to the `/luma/payloads` folder on your SD card
|
|
6. Rename `arm9loaderhax.bin` in `/luma/payloads` to `down_safea9lhinstaller.bin`
|
|
7. Copy the `a9lh` folder from `data_input_v3.zip` to the root of your SD Card
|
|
7. Copy _the contents of_ the arm9loaderhax zip to `a9lh` folder on your SD card
|
|
8. Copy `arm9loaderhax.bin` from the Luma3DS zip to the root of your SD card, overwrite existing files
|
|
9. Reinsert your SD card into your 3DS
|
|
|
|
##### Section II - Payload update
|
|
|
|
10. Boot the device while holding D-Pad down
|
|
11. Press (Select) to update arm9loaderhax
|
|
12. Power off the device and put your SD card back in your computer
|
|
13. Delete the `a9lh` folder from the root of your SD card
|
|
14. Delete `down_safea9lhinstaller.bin` from `/luma/payloads`
|
|
|
|
##### Section III - Configuring Luma3DS
|
|
|
|
15. Reinsert your SD card into your 3DS and boot holding (Select)
|
|
16. 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"**
|
|
3. 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
|
|
4. Press Start to save and reboot
|
|
|
|
##### Section III - CTRNAND Luma3DS
|
|
|
|
16. Open FBI
|
|
17. Select "SD"
|
|
18. Navigate to `arm9loaderhax.bin`, then press (A) on it and select the "Copy" option
|
|
9. Return to the FBI main menu with (B)
|
|
10. Select "CTR NAND"
|
|
11. Select "\<current directory>"
|
|
12. Select the "Paste" option, then press (A) to confirm
|
|
8. Exit with the home button
|
|
9. Power off your 3DS and remove the SD card
|
|
10. Boot with the SD card removed while holding (Select)
|
|
+ Booting the device at least once with the SD card removed will allow you to configure the CTRNAND based luma installation
|
|
16. Use the (A) button and the D-Pad to turn on the following:
|
|
+ **"Show NAND or user string in System Settings"**
|
|
3. If you are using a **New 3DS**, you should *also* enable the following:
|
|
+ **"New 3DS CPU" to "Clock+L2(x)"**
|
