NxNandManager

NxNandManager is a command line (and GUI) utility for Windows 7 & 10, the primary purpose of which is to copy Nintendo Switch content (full NAND or specific partition) from/to a file or physical drive.

Features

• Full NAND backup & restore (BOOT0, BOOT1, RAWNAND)
• Copy from/to specific partition (RAWNAND)
• Dump integrity verification (MD5)
• Enable/Disable auto RCM (BOOT0)

Compatibility

All dumps made with Hekate are supported by NxNandManager (and vice versa).

NxNM also supports splitted dumps (such as SX OS's (emu)NAND dumps).
Split filenames should be :
basename[00->99].(bin|.*) or basename[0->9].(bin|.*) or basename.[0->∝]
Set the first split file as input

How to mount and open your Nintendo Switch's NAND ?

1. Use memloader v3 to mount eMMC on your computer (TegraRcmGUI provides an easy means to do it).
2. Open NxNandManager (CLI : add argument --list to list all available physical drives, GUI : File > Open drive).
3. Select the mounted drive. You can now perform backup/restore operations.

CLI Usage

NxNandManager.exe [--list] [--info] [--enable_autoRCM] [--disable_autoRCM] -i inputFilename|\\.\PhysicalDriveX [-o outputFilename|\\.\PhysicalDriveX] [-part=nxPartitionName] [lFlags]

Arguments	Description	Example
--gui	Launch graphical user interface (optional)	--gui
--info	Display detailed information about input (-i) & output (-o) streams	--info -i rawnand.bin
--list	List compatible physical drives	--list
--enable_autoRCM	Enable auto-RCM for BOOT0 partition indicated with -i param	--enable_autoRCM -i BOOT0 --enable_autoRCM -i "C:\some dir\BOOT0" --enable_autoRCM -i \\.\PhysicalDrive3
--disable_autoRCM	Disable auto-RCM for BOOT0 partition indicated with -i param	--disable_autoRCM -i BOOT0 --disable_autoRCM -i "C:\some dir\BOOT0" --disable_autoRCM -i \\.\PhysicalDrive3
-i	Path to input file or physical drive	-i rawnand.bin -i "C:\some dir\rawnand.bin" -i \\.\PhysicalDrive3
-o	Path to output file or physical drive	-o rawnand.bin -o \\.\PhysicalDrive3
-part=	Copy from/to a specific NAND partition (optional)	-part=PRODINFO -part=BCPKG2-2-Normal-Sub

lFlags	Description
BYPASS_MD5SUM	Used to by-pass all md5 verifications Dump/Restore is faster but less secure
FORCE	Program will never prompt for user confirmation

Examples

Dump full NAND to file

• From physical drive (you first need to mount NX eMMC with memloader (via TegraRcmGUI for ex) :
  .\NxNandManager.exe -i \\.\PhysicalDrive3 -o "C:\Users\Public\NAND dump\rawnand.bin"

• From existing dump file :
  .\NxNandManager.exe -i "C:\Users\Public\NAND dump\rawnand.bin" -o D:\rawnand2.bin

Dump specific partition to file

• Dump SYSTEM partition from physical drive :
  .\NxNandManager.exe -i \\.\PhysicalDrive3 -o "C:\Users\Public\NAND dump\SYSTEM.bin" -part=SYSTEM

• Extract PRODINFOF partition from existing dump file :
  .\NxNandManager.exe -i "C:\Users\Public\NAND dump\rawnand.bin" -o D:\PRODINFOF.bin -part=PRODINFOF

Restore NAND dump

• Restore full raw NAND to physical drive :
  .\NxNandManager.exe -i "C:\Users\Public\NAND dump\rawnand.bin" -o \\.\PhysicalDrive3

• Restore full splitted raw NAND to physical drive :
  .\NxNandManager.exe -i "C:\Users\Public\NAND dump\full00.bin" -o \\.\PhysicalDrive3

• Restore specific partition to physical drive :
  .\NxNandManager.exe -i "C:\Users\Public\NAND dump\rawnand.bin" -o \\.\PhysicalDrive3 -part=PRODINFO
  or
  .\NxNandManager.exe -i "C:\Users\Public\NAND dump\PRODINFO" -o \\.\PhysicalDrive3 -part=PRODINFO

Copy partition from file to rawNand file

• Copy specific partition from rawNand file :
  .\NxNandManager.exe -i "C:\Users\Public\NAND dump\rawnand.bin" -o "C:\Users\Public\NAND dump\rawnand2.bin" -part=BCPKG2-1-Normal-Main

• Copy specific partition from partition file :
  .\NxNandManager.exe -i "C:\Users\Public\NAND dump\BCPKG2-1-Normal-Main" -o "C:\Users\Public\NAND dump\rawnand2.bin" -part=BCPKG2-1-Normal-Main

Build

CLI : MinGW (recommended if not using Visual Studio), MSYS and MSYS2 with GCC

git clone https://github.com/eliboa/NxNandManager   
cd NxNandManager
make

Note : Line #define ENABLE_GUI of "NxNandManager.h" file has to be commented

CLI + GUI (Qt) : MinGW64, MSVC

Dependency : Qt

Visual Studio (Qt Visual Studio Tools needed) : Use NxNandManager.sln solution file

QtCreator : Use NxNandManager/NxNandManager.pro project file
