3DS:Alternate Exploits/Installing boot9strap (SSLoth-Browser)

Technical Details

In order to exploit the Browser application, we need to bypass the browser version check, which is designed to disallow the use of the browser without updating to the latest system version.

A public proxy server is available, which, with the help of the SSLoth exploit, can bypass this check.

Once the bypass is active, an exploit webpage will be accessible which will do the rest of the job.

For technical details on the exploits that you will be using on this page, see here (SSLoth) and here (universal-otherapp).

Compatibility Notes

SSLoth allows users on version 11.13.0 and below to bypass the browser version check, allowing the use of new-browserhax or old-browserhax (compatible with versions 11.4.0 through 11.13.0 in all regions), which can then be used in conjunction with universal-otherapp.

What You Need

• The latest release of SafeB9SInstaller (direct download)
• The latest release of boot9strap (direct download)

Section I - Prep Work

1. Power off your console
2. Insert your SD card into your computer

6. Copy boot9strap.firm and boot9strap.firm.sha from the boot9strap .zip to the /boot9strap/ folder on your SD card
7. Copy SafeB9SInstaller.bin from the SafeB9SInstaller .zip to the root of your SD card
8. Reinsert your SD card into your console
9. Power on your console

2. Tap the QR code button and scan this QR code
   
   • If you get a crash or an error code, follow the troubleshooting guide at the bottom of the page
   • If you get a security certificate warning, press (A) to allow the connection
3. Tap the “PROCEED TO HAXX” button
4. If the exploit was successful, you will have booted into SafeB9SInstaller
   • If you get an error, follow the troubleshooting guide at the bottom of the page

Section IV - Installing boot9strap

   • If a step on the lower screen has red-colored text, and you are not prompted to input a key combo, follow this troubleshooting guide
2. Once it is complete, press (A) to reboot your console
3. Your console should have booted into the Luma3DS configuration menu
   • Luma3DS configuration menu are settings for the Luma3DS custom firmware. Many of these settings may be useful for customization or debugging
   • For the purpose of this guide, leave these options on the default settings (do not check or uncheck anything)
   • 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

   • The test should succeed
7. Power off your console

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.

Failed to mount the SD card!

Back up your data and reformat your SD card as FAT32 with the recommended tool depending on your operating system. MiniTool Partition Wizard and the HP formatting tool (HPUSBDisk) are known to cause issues with 3DS SD cards.

If this is unsuccessful, try using another SD card.
