### Lesen erforderlich

This method of using Seedminer for further exploitation uses your `movable.sed` file to decrypt any DSiWare title for the purposes of injecting an exploitable DSiWare title into the DS Internet Settings application. This requires you to have a DSiWare backup, for example from BannerBomb or the DSiWare Dumper tool.

Dies ist eine zurzeit funktionierende Implementation des "FIRM Partitions Known-Plaintext"-Exploits. Details findest du [hier](https://www.3dbrew.org/wiki/3DS_System_Flaws).

### Was du brauchst

* A DSiWare Backup (such as the one on SD root from [BannerBomb3](bannerbomb3))
* Your `movable.sed` file from completing [Seedminer](seedminer)
* The latest release of [Frogminer_save](https://github.com/zoogie/Frogminer/releases/latest)
* The latest release of [b9sTool](https://github.com/zoogie/b9sTool/releases/latest)
* The latest release of [Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest)

#### Section I - CFW Check

1. Schalte deinen 3DS aus
1. Hold the (Select) button
1. Power on your device while still holding the (Select) button
1. If the check was successful, you will boot to the HOME menu and you may proceed with this guide

If you see a configuration menu, you already have CFW and continuing with these instructions may BRICK your device! Follow [Checking for CFW](checking-for-cfw) to upgrade your existing CFW.

  + If the `Nintendo DSiWare` folder does not exist, create it inside of the `<ID1>`
