NANDFIX is a GUI tool that allows users to unbrick, rebuild, or upgrade Nintendo Switch consoles. It is powered by the EmmcHaccGen and NxNandManager cores, making complex tasks like NAND generation, decryption, encryption, and rebuilding straightforward and accessible. NANDFIX serves as a user-friendly front end, designed to reduce errors and streamline operations compared to using command-line tools alone.

Note: The author has also released a more advanced successor tool called NAND Fix Pro, which features a three-tiered repair system and direct eMMC access via Hekate USB Tools.

Features

• NAND Generation (GENERATE) - Uses the EmmcHaccGen core to create NAND partitions and files based on the provided prod.keys and firmware version.
• NAND Decryption (DECRYPT) - Powered by NxNandManager, decrypts donor NAND partitions with donor.keys.
• NAND Encryption (ENCRYPT) - Re-encrypts partitions with prod.keys.
• NAND Rebuild (BUILD) - Compiles decrypted/encrypted partitions into a new NAND.

Prerequisites

• Windows 7 or higher.
• .NET Desktop Runtime 7.0.20.
• prod.keys extracted from your console using Lockpick_RCM.
• Firmware files.

Installation

Download the latest release from GitHub.
