3DS:Alternate Exploits/Old Finalizing Setup

Required Reading
The file  is what is launched by boot9strap itself after it finishes loading off of NAND. In this case, we are using Luma3DS by LumaTeam to patch the console, allowing it to run homebrew software.

This guide will have you make critical system file backups and install the following homebrew programs:


 * FBI (installs CIA formatted applications)
 * Anemone3DS (installs custom themes)
 * Checkpoint (backs up and restores save files for 3DS and DS games)
 * Universal-Updater (a homebrew app store for downloading homebrew from the 3DS over Wi-Fi)
 * GodMode9 (multipurpose tool which can do NAND and cartridge functions)
 * Homebrew Launcher Loader (launches the Homebrew Launcher)

What You Need

 * The latest release of Anemone3DS (the  file)
 * The v3.7.4 release of Checkpoint (the  file)
