Learn everything about NXNandManager: a powerful Windows tool for managing, mounting, and editing Nintendo Switch NAND backups. Secure your Switch data, recover bricked devices, and explore NAND partitions with ease.
What is NXNandManager?
NXNandManager is a lightweight, Windows-exclusive application designed to help Nintendo Switch users explore, modify, and restore NAND backup files. Commonly used by the modding and homebrew community, it provides an intuitive way to work with full NAND dumps (rawnand.bin) and key partitions such as BOOT0, BOOT1, SYSTEM, and USER.
Whether you’re backing up your data before installing custom firmware (CFW) like Atmosphère or attempting to recover a bricked console, NXNandManager plays a vital role in safe NAND manipulation.

Key Features of NXNandManager
1. 🗃️ NAND Mounting and Partition Browsing
NXNandManager lets users mount decrypted NAND images to explore their file structure, including SYSTEM and USER partitions.
2. 📤 Data Extraction and Injection
You can extract installed titles, save data, or system files — and even inject new content into specific sectors or partitions.
3. 🔑 BIS Key Integration
To read and decrypt the NAND image, the tool requires BIS keys, which are console-specific and must be extracted using tools like Lockpick_RCM.
4. 🧩 Partition Management
Supports full or partial reading/writing of important partitions:
- PRODINFO
- SAFE
- SYSTEM
- USER
5. 🛠️ Brick Recovery Support
If your Switch is soft-bricked or damaged due to failed CFW attempts, NXNandManager can help restore previous backups with minimal effort.

- Hekate – to dump NAND
- Lockpick_RCM – to extract BIS keys
Step 2: Download NXNandManager
- Visit GitHub or trusted Switch modding forums to get the latest release.
- Extract the ZIP and run
NxNandManager.exe.
Step 3: Load Your NAND Backup
- Load
BOOT0,BOOT1, andrawnand.bininto the tool. - Input your BIS keys to decrypt the data.
Step 4: Browse, Extract, or Inject
- Mount the NAND and explore contents.
- Backup critical data or inject modified files as needed.
Step 5: Save and Safely Exit
- Ensure you save any changes before closing.
- Always keep original NAND files safe as a fallback.
Important Safety Tips
- Never modify PRODINFO unless you’re experienced — it’s critical for Switch identity.
- Always work on copies of your NAND backup, not originals.
- Use a verified and updated version of NXNandManager from GitHub to avoid corrupted tools.
