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 (boot.nds)
  • The latest release of Frogminer_save (Frogminer_save.zip)

  2. Hold the (Select) button
  3. Power on your device while still holding the (Select) button

If you see a configuration menu, you already have CFW, and continuing with these instructions may BRICK your device! Follow Checking for CFW to upgrade your existing CFW.
