Dumping NAND
Join the DS⁽ⁱ⁾ Mode Hacking! Discord server for guide development and help.
This page is for making a NAND backup, which is a copy of the data on the Nintendo DSi's internal storage. It can be used to set up hiyaCFW, as well as no$gba and melonDS for DSi emulation.
TIP
It is highly recommended that you do this. A NAND backup can be used as a restore point in the future, in case of a brick.
Section I - SD card setup
TIP
If you have already downloaded dumpTool from another section of this guide, you can skip this section.
- Download the latest release of dumpToolopen in new window
- Place
dumpTool.nds
anywhere on your SD card
Section II - Dumping the NAND
- Launch
dumpTool
through TWiLight Menu++ - Hit the A button on your Nintendo DSi to start dumping your NAND
- A NAND backup typically takes around 7 minutes
- When the NAND backup is complete, hit the START button on your Nintendo DSi to exit dumpTool
- Power off your console and insert your SD card back into your device
- Store this backup somewhere safe, where you won't lose it
- If possible, make multiple backups across different storage devices
- Once you've backed it up elsewhere, you can delete it from the SD card
WARNING
The SHA1 hash of the nand.bin
will not match the hash stored in nand.bin.sha1
. This is because dumpTool adds additional data known as a no$gba footer to the nand.bin
file after the SHA1 hash is calculated. You can use the hiyaCFW Helperopen in new window to create a copy without the footer.
