In this section, you will change your Internet connection settings to use a proxy network designed to exploit the System Update feature of your device.

If you haven’t already, make sure you have a working Internet connection set up on your console.

  8. Click “OK” to continue
  9. 關閉您的主機

Section IV - safecerthax

In this section, you will enter Safe Mode (a feature available on all 3DS family devices) where safecerthax will be triggered, which will launch you into the boot9strap (custom firmware) installer.

  1. With your device still powered off, hold the following buttons: (Left Shoulder) + (Right Shoulder) + (D-Pad Up) + (A), and while holding these buttons together, power on your device
    • Keep holding the buttons until the device boots into Safe Mode (a “system update” menu)
  2. Press “OK” to accept the update
    • There is no update. This is part of the exploit
  3. Press “I accept” to accept the terms and conditions
  4. The update will eventually fail, with the error code 003-1099. This is intended behaviour
  5. Press “OK” to close the error message
  6. 如果一切成功的話,您將自動進入 SafeB9SInstaller
    • If the device freezes or crashes, force power off the device, then retry this section

第五節 — 安裝 boot9strap

In this section, you will install custom firmware onto your device.

  1. When prompted, input the key combo given on the top screen to install boot9strap
  2. Once it is complete, press (A) to reboot your device
  3. Your device should have booted into the Luma3DS configuration menu
    • Luma3DS configuration menu are settings for the Luma3DS custom firmware. Many of these settings may be useful for customization or debugging
    • For the purpose of this guide, leave these options on the default settings (do not check or uncheck anything)
    • If your device shuts down when you try to power it on, ensure that you have copied boot.firm from the Luma3DS .zip to the root of your SD card
  4. 按『Start』鍵以存檔並重新啟動系統

At this point, your console will boot to Luma3DS by default.

  • 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 install useful homebrew applications to complete your setup.
