### 중요

In order to exploit the SAFE_MODE firmware of our system, we need to inject an exploited WiFi profile.

We can do this using an existing exploit, BannerBomb3.

To accomplish this, we use your system's encryption key (movable.sed) to build a DSiWare backup that exploits the system in order to inject the exploited WiFi profile to your connections list.

Once the WiFi profile has been injected, we will use SAFE_MODE, which is a recovery feature present on all 3DS consoles, to activate the exploited WiFi profile.

이 설명서는 미주, 유럽, 일본, 그리고 한국 지역 기기들 (시스템 버전 다음 글짜가 U, E, J, 아니면 K 인 경우) 와 호환됩니다.

If your (Right/Left Shoulder), (D-Pad Up) or (A) buttons do not work, you will need to follow [an alternate branch of Seedminer](bannerbomb3). For assistance with this matter, join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask, in English, for help.

### 준비물

* [Seedminer](seedminer)에서 받은 `movable.sed` 파일
* The latest release of [Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest)

#### 섹션 I - 준비 작업

1. If your device is powered on, power off your device
1. Open [unSAFE_MODE Exploit Injector](https://3ds.nhnarwhal.com/3dstools/unsafemode.php) on your computer
1. "Choose File"를 선택하여 `movable.sed`를 업로드 해 주세요
1. "Build and Download"를 선택해 주세요
  + This will download an exploit DSiWare called `F00D43D5.bin` and a SAFE_MODE exploit data file called `usm.bin` inside of a zip archive (`unSAFE_MODE.zip`)
1. SD 카드를 컴퓨터에 삽입해 주세요
1. Copy `boot.firm` and `boot.3dsx` from the Luma3DS `.zip` to the root of your SD card
  + The root of the SD card refers to the initial directory on your SD card where you can see the Nintendo 3DS folder, but are not inside of it
1. Copy `usm.bin` from `unSAFE_MODE.zip` to the root of your SD card
1. SD 카드의 `Nintendo 3DS` -> `<ID0>` -> `<ID1>` -> `Nintendo DSiWare` 폴더로 이동해 주세요
  + The `<ID0>` will be the same one that you used in [Seedminer](seedminer)
  + The `<ID1>` is a 32 character long folder inside of the `<ID0>`
  + If `Nintendo DSiWare` does not exist, create it inside of the `<ID1>`
1. 만약 다른 DSiWare 백업 파일 (`<8자리-id>.bin`)이 존재 한다면, PC로 옮겨 주세요
  + 이러하여 비어 있는 `Nintendo DSiWare` 폴더가 있을 겁니다. Moving the files to your PC ensures you don't delete any intentional backups
1. Copy the `F00D43D5.bin` file from `unSAFE_MODE.zip` to the `Nintendo DSiWare` folder

#### Section II - BannerBomb3

1. SD 카드를 기기에 다시 삽입해 주세요
1. 기기를 시작해 주세요.
1. 기기에서 본체 설정을 열어 주세요
1. `데이터 관리` -> `DSiWare` 메뉴를 열어 주세요
1. SD 카드 섹션을 열어 주세요
  + Your device should show a menu with some text
1. Select "Inject haxx"
  + Your device will automatically power off

#### Section III - unSAFE_MODE

1. With your device still powered off, hold the following buttons: (Left Shoulder) + (Right Shoulder) + (D-Pad Up) + (A), then press (Power)
  + Keep holding the buttons until the device boots into Safe Mode
1. Press "OK" to accept the update
  + There is no update. This is part of the exploit
1. Press "I accept" to accept the terms and conditions
1. The update will eventually fail, with error code `003-1099`. This is intended behaviour
1. When asked "Would you like to configure Internet settings?", select "Yes"
1. On the following menu, navigate to `Connection 1` -> `Change Settings` -> `Next Page (right arrow)` -> `Proxy Settings` -> `Detailed Setup`
  + This is a [visual representation](https://uwuu.ca/images/safemode_highlighted.png)
1. Once you see `B9S install SUCCESS` on the top screen, press any button to reboot to Luma Configuration

#### 섹션 IV - Luma3DS 설정

1. 여러분의 기기는 Luma3DS 구성 메뉴로 리부팅 됬을 것입니다.
  + If you get a black screen, [follow this troubleshooting guide](troubleshooting#boot-related-issues-on-modded-devices)
1. 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

At this point, your console will boot to Luma3DS by default as long as the SD card is inserted.
  + Luma3DS does not look any different from the normal HOME menu. If your console has booted into the HOME menu, it is running custom firmware.
  + On the next page, you will copy Luma3DS to internal memory so that you can boot without an SD card.

#### Section V - Restoring WiFi Configuration Profiles

1. 기기에서 본체 설정을 열어 주세요
1. `데이터 관리` -> `DSiWare` 메뉴를 열어 주세요
1. SD 카드 섹션을 열어 주세요
  + Your device should show a menu with some text
1. Select "Restore slots"
  + Your device will automatically power off
1. SD 카드를 컴퓨터에 삽입해 주세요
1. SD 카드의 `Nintendo 3DS` -> `<ID0>` -> `<ID1>` -> `Nintendo DSiWare` 폴더로 이동해 주세요
1. Delete `F00D43D5.bin` from your Nintendo DSiWare folder
