<summary><em>Technical Details (optional)</em></summary>
<p>To launch custom code, we exploit a flaw in the DSiWare Data Management window of the Settings application.</p>
<p>To accomplish this, we use your system's encryption key (movable.sed) to build a DSiWare backup that exploits the system.</p>
<p>For a more technical explanation, see <a href="https://github.com/zoogie/Bannerbomb3">here</a>.</p>

### Compatibility Notes

If you have a Taiwanese console (indicated by a T after the system version), follow [this page](bannerbomb3-fredtool-(twn)) instead.

  ![]({{ "/images/screenshots/bb3/dsiware-location-1.png" | absolute_url }}){: .notice--info}
1. Create a folder named `Nintendo DSiWare` inside of the `<ID1>`

  + Keep holding the buttons until the device boots into Safe Mode (a "system update" menu)
1. If prompted to update, press Cancel
  + Your device will power off
  + If the device boots to the HOME Menu, just power off your device
