Due to legal restrictions, I cannot provide direct links. However, I can describe where the community safely archives these files.

Warning: Downloading copyrighted Nintendo 3DS update files from unauthorized sources may violate intellectual property laws in your jurisdiction. This guide assumes you own a legitimate copy of the base game, which you are legally updating via a backup utility. If you do not own the game, you are engaging in piracy.

Once you have CFW and an installer (like FBI), follow these steps:

Step 1: Transfer Files

Step 2: Open FBI

Step 3: Navigate to the File

Step 4: Install

Step 5: Launch

Standard installation process:

Pro Tip: Always install the Base CIA first, then the UPD. Installing the update first may cause an error.
