3DS:Alternate Exploits/Installing boot9strap (Frogtool)

Required Reading

We will now use our Homebrew Launcher access to run the Frogtool utility in order to inject the exploitable Japanese version of the "Flipnote Studio" title, which we then use to run b9sTool and install boot9strap.

This is a currently working implementation of the "FIRM partitions known-plaintext" exploit detailed here.

To use the magnet links on this page, you will need a torrent client like Deluge.

If the process was successful, tap the touch screen, then select "BOOT patched DS Download Play"
If the exploit was successful, your device will have loaded the JPN version of Flipnote Studio
- If you get stuck on a black screen, follow this section, then try again

Section IV - Flipnote Exploit

In this section, you will perform a series of very specific steps within Flipnote Studio that, when performed correctly, will launch b9sTool, the boot9strap (custom firmware) installer.

If you would prefer a visual guide to this section, one is available here.

Complete the initial setup process for the launched game until you reach the main menu
- Select the left option whenever prompted during the setup process
Using the touch-screen, select the large left box, then select the box with an SD card icon
Once the menu loads, select the face icon, then the bottom right icon to continue
Press (X) or (UP) on the D-Pad depending on which is shown on the top screen
Select the second button along the top with a film-reel icon
Scroll right until reel “3/3” is selected
Tap the third box with the letter “A” in it
Scroll left until reel “1/3” is selected
Tap the fourth box with the letter “A” in it
If the exploit was successful, your console will have loaded b9sTool

Section V - Installing boot9strap

In this section, you will install custom firmware onto your console.

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 open DS Download Play and start over from the beginning of this section
Press (A), then press START and SELECT at the same time to begin the process
Once completed and the bottom screen says “done.”, exit b9sTool, then power off your console
- You may have to force power off by holding the power button
- If your console shuts down when you try to power it on, ensure that you have copied boot.firm from the Luma3DS .zip to the root of your SD card
- If you see the Luma Configuration screen, power off your console and continue to the next section

Section VI - Luma3DS Configuration

Press and hold (Select), and while holding (Select), power on your device. This will launch Luma3DS configuration

- For the purpose of this guide, these settings will be left on default settings
- If you boot to HOME Menu, follow this troubleshooting guide
Press (Start) to save and reboot

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.
