sysDowngrader is a quick tool for manually downgrading a 3DS using CIA files.

This is not intended for installing anything else. You also should strictly avoid updating single titles because this also can lead to bricks.

Note: Use this software at your own risk.

Installation

Install this app to your system. It updates whatever NAND (sysNAND/emuNAND) it is installed on.

Create the directory updates in the root of the SD card of your 3DS.

Create update CIAs from Nintendos update server or get them from gamecards. With 3DNUS for example.

Place all the created .cia files in the updates directory you created earlier.

User guide

Start the app and follow the instructions.

Downgrade means it uninstalls the title first if the installed versions are newer.
