##### Section II - ntrboot

1. Use the magnet to find the spot on your device where the sleep sensor is triggered

1. 關閉您的主機
1. Insert your flashcart into your device
1. Place the magnet on your device to trigger the sleep sensor
  + On old 2DS, you should instead enable the sleep mode switch
1. Hold (Power) + (Start) + (Select) + (X) for several seconds, then release the buttons
  + It may take a few attempts to get this to work because the positioning is awkward
1. 如果一切成功的話，您將自動進入 SafeB9SInstaller

##### 第三節 — 安裝 boot9strap

1. 等待所有安全性檢查完畢
1. 出現提示時，輸入提示的按鍵組合以安裝 boot9strap
1. Once it has completed, force your device to power off by holding down the power button
  + Your device will only boot to the SafeB9SInstaller screen until the next section is completed

1. 將 SD 卡插入電腦中
1. Delete `boot.firm` from the root of your SD card
1. 解壓 Luma3DS `.7z` 內的 `boot.firm` 到 SD 卡的根目錄底下

  + 如果黑屏，[請參見此疑難排解](troubleshooting#ts_sys_b9s)
1. 透過方向鍵及「A」以開啟下列選項：    
  + **「Show NAND or user string in System Settings」**
