### Required Reading

The instructions on this page do not currently work on the latest firmware (11.16.0). If you were directly linked to this page, [return to Seedminer](Seedminer) or join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask, in English, for help.
{: .notice--warning}

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.

This is a currently working implementation of the "FIRM partitions known-plaintext" exploit detailed [here](https://www.3dbrew.org/wiki/3DS_System_Flaws).

### What You Need

* A DSiWare Backup (You should have one on the root of your SD card from following [BannerBomb3](bannerbomb3))
* Your `movable.sed` file from completing [Seedminer](seedminer)
* The latest release of [Frogminer_save](https://github.com/zoogie/Frogminer/releases/latest) (`Frogminer_save.zip`)
* The latest release of [b9sTool](https://github.com/zoogie/b9sTool/releases/latest) (`boot.nds`)
* The latest release of [Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest) (the Luma3DS `.zip` file)

#### Section I - CFW Check

1. Power off your device
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.

1. If the exploit was successful, your device will have loaded b9sTool
1. Using the D-Pad, move to "Install boot9strap"
  + If you miss this step, the system will exit to HOME Menu instead of installing boot9strap and you will need to start over from Step 12 of Section III

1. Once completed and the bottom screen says "done.", exit b9sTool, then power off your device
  + You may have to force power off by holding the power button

At this point, your console will boot to Luma3DS by default.
  + Luma3DS does not look any different from the normal HOME Menu. If your console has booted into the HOME Menu, it is running custom firmware.
  + On the next page, you will install useful homebrew applications to complete your setup.

#### Section VI - Restoring DS Connection Settings

1. Copy the `42383841.bin` file from the `output/clean/` folder of the downloaded DSiWare archive (`fredtool.zip`) to the `Nintendo 3DS/<ID0>/<ID1>/Nintendo DSiWare/` folder on your SD card
