--- title: "Updating A9LH" permalink: /updating-a9lh.html --- ### 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). {: .notice--info} 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). {: .notice--info} These steps will also update your various payloads and the AES key database. {: .notice--success} #### What you need * [`aeskeydb.bin`](torrents/aeskeydb.torrent) - * [`data_input_v3.zip`](torrents/data_input_v3.torrent) - * The latest release of [Luma3DS](https://github.com/AuroraWright/Luma3DS/releases/latest) * The latest release of [arm9loaderhax](https://github.com/AuroraWright/arm9loaderhax/releases/latest) * The latest release of [SafeA9LHInstaller](https://github.com/AuroraWright/SafeA9LHInstaller/releases/latest) * The latest release of [Hourglass9](https://github.com/d0k3/Hourglass9/releases/latest) #### 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 "\" 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)"** + 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 14. Reinsert your SD card, then press Start to save and reboot!
