<summary><em>Technical Details (optional)</em></summary>
<p>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.</p>
<p>A public proxy server is available, which, with the help of the SSLoth exploit, can bypass this check.</p>
<p>Once the bypass is active, an exploit webpage will be accessible which will do the rest of the job.</p>
<p>For technical details on the exploits that you will be using on this page, see <a href="https://github.com/MrNbaYoh/3ds-ssloth">here</a> (SSLoth) and <a href="https://github.com/TuxSH/universal-otherapp/">here</a> (universal-otherapp).</p>

### 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.

If you have updated your device to your current version using a cartridge, your Internet Browser will be inaccessible. If this is the case, you will need to update your device to the latest version through System Settings and then follow the method for the latest version.

### What You Need

* The latest release of [SafeB9SInstaller](https://github.com/d0k3/SafeB9SInstaller/releases/download/v0.0.7/SafeB9SInstaller-20170605-122940.zip) (direct download)
* The latest release of [boot9strap](https://github.com/SciresM/boot9strap/releases/download/1.4/boot9strap-1.4.zip) (direct download)
* The latest release of [Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest) (the Luma3DS `.zip` file)
* The latest release of [universal-otherapp](https://github.com/TuxSH/universal-otherapp/releases/latest) (`otherapp.bin`)

#### Section I - Prep Work

In this section, you will copy the files needed to trigger both browserhax and universal-otherapp.

1. Power off your device
1. Insert your SD card into your computer
1. Copy `otherapp.bin` to the root of your SD card and rename it to `arm11code.bin`
  + 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
  + If you do not see the `.bin` extension, do not add it to the end of the filename
1. Copy `boot.firm` and `boot.3dsx` from the Luma3DS `.zip` to the root of your SD card
1. Create a folder named `boot9strap` on the root of your SD card
1. Copy `boot9strap.firm` and `boot9strap.firm.sha` from the boot9strap `.zip` to the `/boot9strap/` folder on your SD card
1. Copy `SafeB9SInstaller.bin` from the SafeB9SInstaller `.zip` to the root of your SD card
1. Reinsert your SD card into your device
1. Power on your device

#### Section II - SSLoth

In this section, you will change your Internet connection settings to use a proxy network designed to bypass the browser version check, allowing the browser to function without a system update. This will allow you to access the browser exploit webpage in the next section.

1. Launch the System Settings application
1. Navigate to `Internet Settings` -> `Connection Settings`
1. Click on your network connection slot and navigate to `Change Settings` -> `Next Page (right arrow)` -> `Proxy Settings`
1. Set "Proxy Settings" to "Yes", then click `Detailed Setup`
1. Set the Proxy Server to `192.9.234.11`, and the Port to `8080`
1. Click OK, then click Save
1. When prompted, click "Test" to perform the connection test
  + The test should succeed
1. Click "OK" to continue
1. Press "Back" twice, then "Close" to go back to the HOME Menu

#### Section III - Launching SafeB9SInstaller

In this section, you will visit the browser exploit webpage, which will use universal-otherapp to launch the boot9strap (custom firmware) installer.

1. On the HOME Menu, press the Left and Right shoulder buttons together to open the camera
    + If you are unable to open the camera, open the Internet Browser and manually type the URL instead (`https://zoogie.github.io/web/nbhax/`)
1. Tap the QR code button and scan [this QR code](http://api.qrserver.com/v1/create-qr-code/?color=000000&bgcolor=FFFFFF&data=https%3A%2F%2Fzoogie.github.io%2Fweb%2Fnbhax&qzone=1&margin=0&size=400x400&ecc=L)
  + If you get an error, [follow this troubleshooting guide](troubleshooting#installing-boot9strap-ssloth-browser)
  + If you get a security certificate warning, press (A) to allow the connection
1. Tap the "PROCEED TO HAXX" button
1. If the exploit was successful, you will have booted into SafeB9SInstaller

#### Section IV - Installing boot9strap

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

1. When prompted, input the key combo given on the top screen to install boot9strap
1. Once it is complete, press (A) to reboot your device
1. Your device should have rebooted into the Luma3DS configuration menu
  + If your device 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
1. Press (Start) to save and reboot
  + If you get an error, just continue to the next page

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 V - Restoring default proxy

In this section, you will restore the Internet settings back to normal.

1. Launch the System Settings application
1. Navigate to `Internet Settings` -> `Connection Settings`
1. Click on your network connection slot and navigate to `Change Settings` -> `Next Page (right arrow)` -> `Proxy Settings`
1. Set "Proxy Settings" to "No"
1. Click OK, then click Save
1. When prompted, click "Test" to perform the connection test
	+ The test should succeed
1. Power off your device
