3DS:Bannerbomb3/Preparation

Technical Details

To launch custom code, 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.

For a more technical explanation, see here.

Compatibility Notes

These instructions work on USA, Europe, Japan, and Korea region consoles as indicated by the letters U, E, J, or K after the system version.

What You Need

• Your movable.sed file from completing Seedminer

Instructions

Section I - Prep Work

1. Power off your device
2. Insert your SD card into your computer
3. Open Bannerbomb3 Injectoron your computer
4. Upload your movable.sed using the “Choose File” option
5. Click “Build and Download”
   • This will download an exploit DSiWare called F00D43D5.bin and a payload called bb3.bin inside of a zip archive (DSIWARE_EXPLOIT.zip)
6. Copy bb3.bin from DSIWARE_EXPLOIT.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
7. Navigate to Nintendo 3DS -> <ID0> -> <ID1> on your SD card
   • <ID0> is the 32-letter folder name that you copied in Seedminer
   • <ID1> is a 32-letter folder inside of the <ID0>
8. Create a folder named Nintendo DSiWare inside of the <ID1>
   • If you already had the folder *and* there are any existing DSiWare backup files (<8-character-id>.bin) inside, copy them to your PC and remove them from your SD card
9. Copy the F00D43D5.bin file from DSIWARE_EXPLOIT.zip to the Nintendo DSiWare folder
