3DS:Bannerbomb3/Installing boot9strap (Fredtool)

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 Internet, which can be used to install custom firmware.

What you need

• Your movable.sed file completing Mii Mining
• The latest release of Luma3DS (the Luma3DS .zip file)
• The 6.0.1 release of b9stool for 11.15.0-47 (direct download)
• The latest release of Frogminer_save (direct download)

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

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

Section II - Prep Work

1. Power off your device
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
