Required Reading

To dump system DSiWare, we exploit a flaw in the DSiWare Data Management window of the Settings application.

To accomplish this, we use your system’s encryption key (movable.sed) to build a DSiWare backup that exploits the system to dump the DSi Internet Settings application to the SD root.

Once you have a DSiWare backup, an exploitable DSiWare title can be injected into DS Download Play, which can be used to install custom firmware.

These instructions are for Taiwanese consoles ONLY (as indicated by a T at the end of the system version, e.g. 11.16.0-39T)! If your console is from any other region, choose the other method.

What you need

  • Your movable.sed file completing Seedminer
  • The latest release of Luma3DS (the Luma3DS .zip file)
  • The latest release of b9stool (direct download)
  • The latest release of Frogminer_save (Frogminer_save.zip)

Section I - CFW Check

As an additional safety measure, we will perform an additional check for custom firmware. This is because using this method when custom firmware is already installed has a risk of bricking the console (rendering it unusable without recovery methods like ntrboot).

  1. Power off your console
  2. Hold the (Select) button
  3. Power on your console while still holding the (Select) button
  4. If the check was successful, you will boot to the HOME Menu and you may proceed with this guide
  5. Power off your console

If you see a configuration menu or the console immediately powers off, you already have CFW, and continuing with these instructions may BRICK your console! Follow Checking for CFW to upgrade your existing CFW.

Section II - Prep Work

  1. Power off your console
  2. Insert your SD card into your computer
  3. Copy boot.firm and boot.3dsx from the Luma3DS .zip 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. Copy boot.nds (B9STool) from the release .zip to the root of your SD card
  5. Copy the private folder from the Frogminer_save .zip to the root of your SD card
  6. Keep your SD card in your computer - there are more things to do in the next section
