title: "Updating to boot9strap"
---

This page is for existing arm9loaderhax users to update their devices to boot9strap.
{: .notice--info}

All future releases of Luma3DS will only be made in the `.firm` format, which will only be compatible with boot9strap and sighax. This means that to continue receiving the latest updates of Luma3DS, you should use this page to update your installation.
{: .notice--info}

If you have a PIN enabled on Luma3DS, SafeB9SInstaller will give you an "OTP Crypto Fail" error unless you *either* temporarily disable your PIN (you can re-enable the PIN after the update), *or* download the `aeskeydb.bin` file below.

#### 준비물

Note that the following required file named `secret_sector.bin` is the same one that was found in the various `data_input.zip` file versions. If you already have that file on your disk somewhere, you can use that one instead of downloading the one below.
{: .notice--info}

Note that, on New 3DS, `secret_sector.bin` is needed to revert the arm9loaderhax exploit, which is why it is not needed for the installation of boot9strap on a stock console. If you do not have a New 3DS, you do not need `secret_sector.bin`.
{: .notice--info}

Note that the the following required file named `aeskeydb.bin` is *not* the same one that was previously used in this guide. It is required to remove the software "3DSafe" as it allows SafeB9SInstaller to retrieve your console unique OTP. This guide has never instructed you to install "3DSafe", so if you do not remember installing it, you most likely do not have it and do not need `aeskeydb.bin`.

    {: .notice--info}

1. SD 카드를 기기에 다시 삽입해 주세요.

##### Section II - Installing boot9strap

1. Boot your device while holding (Start) to launch the Luma3DS chainloader menu
  + Some versions of Luma3DS will just directly start whichever payload begins with `start_`
  + If your version does this, just proceed with the instructions
1. Launch SafeB9SInstaller by pressing (A) on it
  + If this gives you an error, try either using a new SD card, or formatting your current SD card (backup existing files first)
1. Wait for all safety checks to complete
1. When prompted, input the key combo given to install boot9strap
1. Once it has completed, press (A) to reboot your device.
  + If your device shuts down on boot, ensure that you have copied `boot.firm` from the Luma3DS `.7z` to the root of your SD card

##### 섹션 III - Luma3DS 설정

This section is only needed if you are prompted with the Luma3DS configuration menu after the reboot.
{: .notice--info}

1. In the Luma3DS configuration menu, use the (A) button and the D-Pad to turn on the following:    
  + **"Show NAND or user string in System Settings"**
1. (start)를 눌러 저장하고 기기를 다시 시작해 주세요.

##### 섹션 IV - CTRNAND Luma3DS

If, before updating to boot9strap, 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) before doing this section.
{: .notice--info}

1. (B)를 눌러 메인 메뉴로 돌아가 주세요.
1. `[0:] SDCARD`로 이동해 주세요.

  + If you have files or folders *other than* the ones from following an earlier version of this guide (`config.bin` and `payloads`) in your `luma` directory (such as LayeredFS files), you should instead just copy `config.bin` and `payloads` by marking them with the (L) trigger, then pressing (Y) to copy
1. (B)를 눌러 메인 메뉴로 돌아가 주세요.
1. Navigate to `[1:] SYSNAND CTRNAND` -> `rw`

{: .notice--info}

Note that `firm0firm1.bak` and `sector0x96.bak` in the `/boot9strap/` folder on your SD card are only needed in the event of a failed boot9strap install. Once you have installed successfully, you can delete the entire `boot9strap` folder.
