Required Reading

This method of using Seedminer for further exploitation uses your movable.sed file to write a custom save file for Pokémon Picross, which can then be used with universal-otherapp to run SafeB9SInstaller.

What You Need

  • The game “Pokémon Picross” (free on eShop) installed on your device
    • You can scan this QR code using the Nintendo 3DS Camera for a direct link to the eShop app
    • Your SD card must be inserted in your device to install Pokémon Picross
  • Your movable.sed file from completing Seedminer
  • The latest release of SafeB9SInstaller
  • The latest release of boot9strap (boot9strap-1.3.zip; not the devkit file, not the ntr file)
  • The latest release of Luma3DS
  • The latest release of universal-otherapp

Instructions

Section I - Prep Work

  1. Power off your device
  2. Insert your SD card into your computer
  3. Copy otherapp.bin to the root of your SD card
  4. Copy boot.firm and boot.3dsx from the Luma3DS .zip to the root of your SD card
  5. Create a folder named boot9strap on the root of your SD card
  6. Copy boot9strap.firm and boot9strap.firm.sha from the boot9strap .zip to the /boot9strap/ folder on your SD card
  7. Copy SafeB9SInstaller.bin from the SafeB9SInstaller .zip to the root of your SD card

Section II - PicHaxx

  1. Open the PicHaxx Injector website on your computer
  2. Select your movable.sed file
  3. Select “Build and Download”
  4. Wait for the process to complete
  5. Navigate to Nintendo 3DS -> <ID0> -> <ID1> -> title -> 00040000 -> 0017c100 -> data on your SD card
    • The <ID0> will be the same one that you used in Seedminer
    • The <ID1> is a 32 character long folder inside of the <ID0>
  6. Copy the newly downloaded 00000001.sav file to the data folder on your SD card
    • Overwrite the old save file when prompted
  7. Reinsert your SD card into your device
  8. Power on your device
  9. Launch “Pokemon Picross”
  10. If the exploit was successful, your device will have booted into SafeB9SInstaller

Section III - Installing boot9strap

  1. Wait for all safety checks to complete
  2. When prompted, input the key combo given to install boot9strap
  3. Once it has completed, press (A) to reboot your device

Section IV - Configuring Luma3DS

  1. Your device should have rebooted into the Luma3DS configuration menu
  2. Use the (A) button and the D-Pad to turn on the following:
    • “Show NAND or user string in System Settings”
  3. Press (Start) to save and reboot

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.

At this point, Pokémon Picross is no longer necessary and can be removed from your device.
