Required Reading

This method of accessing the Homebrew Launcher takes advantage of some browser oversights in the native 3DS Internet Browser.

These instructions work on USA, Europe, Japan, and Korea region consoles as indicated by the letters U, E, J, or K after the system version. If you have a Taiwan or China region console as indicated by the letters T or C after the system version, join Nintendo Homebrew on Discord and ask, in English, for help.

What You Need


Section I - Prep Work

  1. Power off your console and remove the SD card
  2. Connect the SD card to your computer
  3. Copy boot.3dsx from the Homebrew Launcher release 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
  4. In the BrowserHax release archive, open the folder corresponding to your console’s region
    • Your console’s region can be found in the final letter of the system version in System Settings: U is USA, E is EUROPE, J is JAPAN, and K is KOREA
  5. Copy the 3ds folder, browserhax_hblauncher_ropbin_payload.bin and arm11code.bin from there to the root of your SD card
    • You should now have a Nintendo 3DS folder, a 3ds folder and the two .bin files on your root directory

Section II - BrowserHax

  1. Open this image in a new tab or window on your computer
  2. Safely remove your SD card from your computer and put it back in your console
  3. Power on your console and ensure it is connected to an active WiFi network
  4. From the HOME Menu, press the Left Shoulder and Right Shoulder buttons together
    • This should open a QR Scanner. If it does not, USM (the next part of getting custom firmware) will not work for you. You will need to use Seedminer
    • If you need to type out the URL, it is https://zoogie.github.io/web/nbhax/
  5. Use the QR scanner to scan the QR code you opened in the first step
  6. Tap the “PROCEED TO HAXX” button
  7. Wait for the process to complete
  8. If the exploit was successful, your device will have loaded the Homebrew Launcher
    • If you see an error stating that no applications were found, ensure that you have copied the 3ds folder from the BrowserHax release archive to the root of your SD card, then try this section again
  9. Leave your console on and proceed to the next section below
