### 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.

This process will overwrite your Pokémon Picross save file, if you have one. If you wish to preserve your Pokémon Picross game data, you should make a backup of your `00000001.sav` file before overwriting it.

1. Reinsert your SD card into your device
1. Power on your device
1. Launch "Pokémon Picross"
1. If the exploit was successful, your device will have booted into SafeB9SInstaller

#### Section III - Installing boot9strap

1. When prompted, input the key combo given on the top screen to install boot9strap
  + If the top screen is blank, reboot your device and re-launch Pokémon Picross
1. Once it is complete, press (A) to reboot your device

#### Section IV - Configuring Luma3DS

1. Your device should have rebooted into the Luma3DS configuration menu
  + You can access the Luma3DS configuration menu at any time by powering off, holding SELECT, then powering on your device while still holding SELECT
  + If you get a black screen, [follow this troubleshooting guide](troubleshooting#boot-related-issues-on-modded-devices)

1. 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. If you wish to play the game, restore your `00000001.sav` backup or re-download the game from the Nintendo eShop.
