Nintendo Switch NAND management tool: explore, backup, restore, mount, resize, create emunand, etc. (Windows).
Features
- Backup or restore any Switch's NAND (file or drive) => full sysNAND, full emuNAND, boot partitions or user partitions.
- Encrypt or decrypt native encrypted partition (PRODINFO, PRODINFOF, SAFE, SYTEM & USER) using BIS keys.
- Resize your NAND (USER partition only).
- Retrieve and display useful information about NAND file/drive (Firmware version, device ID, exFat driver, S/N, etc.) using BIS keys.
- Splitted dumps are fully supported (backup & restore). However the program cannot split an existing dump nor can it split the output file in any case.
- Option to wipe console unique ids and certificates (a.k.a Incognito) from PRODINFO.
- Enable/Disable auto RCM (BOOT0).
- Create emuNAND (file or partition based) from any NAND image (RAWNAND or FULL NAND).
- "Advanced copy" feature (passthrough zeroes, split output, zip output, etc).
- Mount any FAT partition (USER, SYSTEM, etc.) as virtual disk. Follow steps to install Dokan's driver first.
- Explorer (Beta):
- Explore the content of USER & SYSTEM partitions. Provides useful info: title name & id, user name & id, etc.
- List, save or extract files from saveFS (title saves, under /save folder)
- List, save, decrypt or extract content from NCAs (installed titles) using hactoolnet Png
User guide
Supported file format
It should be noted that the program does not check the file extension to detect if a file is supported or not. It'll look for specific signature inside binary data (magic number) when possible.
If the file is fully encrypted, the program will detect the type by inspecting the filename (without extension) and the file size. Therefore, a single partition file (encrypted) should be named after the partition name ("SAFE.bin", "SAFE.enc" or "SAFE.whatever" will work, "SAFE_01.bin" will not).
Supported drives
NxNandManager can detect physical drives that contains a valid NAND (or partition) such as memloader drives (tool for mounting Nintendo Switch's NAND on a computer) or SD card containing an emuNAND partition (SX OS hidden partition or emuMMC partition).
How to open your Nintendo Switch's NAND (GUI)
sysNAND or emuNAND (via Hekate):
- Launch Hekate/Nyx (v5.2+) on your Nintendo Switch. Navigate to Tools > USB Tools.
- Either select "eMMC RAW GPP" (sysNand) or "emu RAW GPP" (emuNAND) to mount your NAND on your computer (you can mount BOOT0/BOOT1 separately).
- Set "Read-Only" to OFF if you want to perform restore operations.
- Open NxNandManager then open new drive (CTRL + D).
- Select the mounted drive. You can now perform backup/restore operations.
emuNAND (partition):
- Mount the SD card containing emuNAND on your computer.
- Open NxNandManager then open new drive (CTRL + D).
- Select the drive labelled "FULL NAND".
emuNAND (files):
- Mount the SD card containing emuNAND on your computer
- Open NxNandManager then open new file (CTRL + O).
- Open the first split file of your emuNAND (i.e "sdmmc:\emuMMC\SD00\eMMC\00" for emuMMC or "sdmmc:\sxos\emunand\full.00.bin" for SX OS's emuNAND)

Notes on transfer speed
Performance depends greatly on hardware/drive limitations. For example, if you're doing backup/restore operations on a drive mounted through "memloader", the transfer speed will be very slow, due to memloader limitations.
That said, the transfer rate will be reduced if you choose to encrypt or decrypt data. Data integrity validation (MD5 hash) can also affect the tranfer rate.
Compatibility
All dumps made with Hekate are supported by NxNandManager (and vice versa).
NxNandManager 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.

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
NAND decryption/encryption (AES-XTS)
NxNandManager can decrypt or encrypt NAND file/drive (rawnand or encrypted partition file "PRODINFO", "SAFE", "SYSTEM", etc). A keyset file containing biskeys must be provided.
Use -d argument to decrypt, -e to encrypt.
Keys can be provided by the -keyset argument to the keyset filename. The program can parse keyset files made with biskeydump or lockpick:
BIS Key 0 (crypt): <16-byte hex key> BIS Key 0 (tweak): <16-byte hex key> ...
or
bis_key_00 = <32-byte hex key> bis_key_01 = <32-byte hex key> ...
When -keyset and --info arguments are provided, the program can also retrieve some useful information, such as firmware version, exFat driver, last boot time, etc.
Examples:
Decrypt full rawnand:
NxNandManager.exe -i rawnand.bin -o rawnand.dec -d -keyset keys.dat
Decrypt single partition file:
NxNandManager.exe -i PRODINFO -o PRODINFO.dec -d -keyset keys.dat
Encrypt single partition file:
NxNandManager.exe -i PRODINFO.dec -o PRODINFO.enc -e -keyset keys.dat
Decrypt & restore single partition file to physical drive:
NxNandManager.exe -i PRODINFO.dec -o \\.\PhysicalDrive3 -part=PRODINFO -e -keyset keys.dat
Encrypt & restore full rawnand:
NxNandManager.exe -i rawnand.dec -o \\.\PhysicalDrive3 -e -keyset keys.dat

- Many fixes and improvements.
- Edit April 25: #26 fixed.
- Edit April 30 : #27 fixed.
v3.0.3 2019/11/14
- Fix USER's boot sector when creating resized NAND larger than 32Gb (Horizon OS was unable to detect the real size of USER partition).
v3.0.2 2019/11/03
- GUI : Fixed a bug that caused backup GPT not to be found for RAWNAND as a memloader drive (#10).
- GUI : Fixed a bug that caused BCPKG2 partitions not to be recognized (#8).
- Input volume is now locked before making dump/restore to prevent any other process from writing to volume during operation.
- Misc fixes.
v3.0.1 2019/11/01
- Writing to emuMMC partition is fixed (#6).
- Fixed an error when input or output path contains non latin characters (#5).
- Edit 11/02 : this release was updated with a quick fix for emuMMC partition detection bug on Windows 7 (#7).
v3.0.0 2019/10/27
- Edit : Writing to emuMMC is broken :/ I'm working on it. It should still work for SX OS hidden partition though.
Added suppport for SD partition emuMMC and SX OS hidden partition (emuNAND):
- Thus, support for a new NxStorage type "FULL NAND" was added. FULL NAND contains BOOT0, BOOT1 and RAWNAND in a single file/storage. You can pretty much perform the same operations to FULL NAND and RAWNAND (dump, restore, decrypt partition, dump partition, etc).
- Additionally, you can extract RAWNAND from FULL NAND as well as BOOT0 & BOOT1 (CLI : use argument -part=RAWNAND, -part=BOOT0,etc. GUI : "Tools" > "Dump RAWNAND only"). You can also restore FULL NAND to RAWNAND (BOOT0 and BOOT1 will be skipped) and vice versa.
- To open your emuNAND partition, mount your SD card on your computer, then :
- GUI : Use shortcut
CTRL+Dto list compatible drives, then select the detected drive, labelled "FULL NAND". - CLI usage : use
command NxNandManager.exe --listto get the disk name to use with input argument "-i".
- GUI : Use shortcut
Resize NAND:
- You can now resize any RAWNAND or FULL NAND storage. The resize feature will create a new file for your NAND with resized USER partition. This is mainly useful to reduce the size of your emuNAND (file or partition) but you can also increase the size of USER partition, above 26 Gb. Optionally, USER partition can be formatted while resizing.
CLI : a list of partition can now be provided through argument "-part":
- In case you want to dump or restore several partitions at the same time, you can provide a list of partitions, seperated by a comma, through "-part=" argument. In this case, output must be a directory. When output is a valid NxStorage (restore), every partition that exists in both input and output, will be restored to output.
- One thing to remember is that when argument -part is provided, the program will never copy the GPT (partition table).
Misc.:
- Restoring to splitted dump is now allowed.
- When keyset is provided, the program can retrieve new information:
- device ID (can be useful to disable parental control).
- WLAN mac address.
- Available FAT32 space for partitions SYTEM & USER.
- Improved BOOT1 detection (will look for magic PK11 in the entire file).
- Except for some GUI parts, the whole code has be refactored. Although this is mainly transparent for end user, you should notice a general improvement in performance when copying (except when using memloader which is still super slow).
- CLI : remaining time and amount of bytes copied are now displayed during copy.
v2.0.2 2019/09/20
- Added support for 9.0 RAWAND firmware detection.
- Added support for 9.0 BOOT1.
- Improved firmware detection : since nca filename based detection is not so accurate, the program will also and always search in journal/play reports for firmware version (opening rawnand or SYSTEM partition will be a bit slower, especially with memloader).
v2.0.1 2019/08/14
- Added support for emuMMC (SD Files). Restoring to a splitted dump is still not supported but you can dump/join and decrypt emuMMC, or install incognito on emuMMC (open the file "sdmmc:\emuMMC\SD00\eMMC\00" to open your emuMMC).
- Fixed error when installing incognito on splitted dump.
