Installing Unlaunch (TempNAND)

If you need help, ask the NDS(i)Brew Scene or the Nintendo Homebrew Discord servers.

If you do not have a DSiWare exploit already installed, you must have a console with Flipnote Studio installed, or a hardware modification capable of installing DSiWare.

This method severely degrades the NAND and should only be used as a last resort.

Requirements

The latest release of Unlaunch
The latest release of HBMenu
The latest release of ugopwn
The 1.6 release of fwTool
The latest release of TempNAND
The latest release of Java
The latest release of Python 3
The latest release of DSi SRL Extractor
The latest release of No$GBA
A random .nds rom file

Preparing SD card

Copy the contents of the fwTool .zip file to the root of your SD card
Copy BOOT.NDS from the hbmenu folder in the HBMenu .tar.bz2 file to the root of your SD card
Copy the contents of the ugopwn .zip file to the root of your SD card

Dumping key files

Open the System Settings application
Select Data Management > System Memory > Flipnote Studio > Copy > Yes
- If Data Management isn’t appearing, open the DSi Shop, close it, and then try again
Exit to the DSi Menu
Open the Flipnote Studio application
- Ensure that the booting to Calendar mode is disabled in Flipnote Studio’s settings
- If you already have another DSiWare exploit installed, open that and skip to Step 17
Select View Flipnote > SD Card > Select Folder > User > ugopwn
Click on the note with the red bottom half
Select “Edit”
Click on the Flipnote frog icon in the bottom left
Click on the film roll icon
Select Copy > Back > Exit
Click the second note.
Click on the Flipnote frog icon in the bottom left
Click on the film roll icon.
USA/EUR/AUS: Click on the single right arrow (the next to last arrow icon) two times
- You will see a new frame be created
Based on your region, do the following:
- USA: Click on the paste button exactly 122 times.
- EUR/AUS: Click on the paste button exactly 2 times.
- JPN: Click on the paste button.
USA/EUR/AUS: Select “Erase” and then “Paste”
- This will launch HBMenu
Navigate to fwtool.nds, and press (A)
- fwTool will appear
Select the options Dump CID and Dump BIOS
Select Dump nand_dsi.bin
- This will take a few minutes
Once finished, power off your device

Preparing for TempNAND and No$GBA

Download and extract the No$GBA .zip file to a folder on your Desktop
Insert your SD card into your computer
Open the folder in your SD card with seemingly random numbers
Copy the DSi BIOS to the NO$GBA folder
Copy nand_dsi.bin to a safe location on your computer
Rename nand_dsi.bin to clean_nand_dsi.bin
Copy CID.bin to a safe location on your computer
Copy the contents of the Unlaunch .zip file to a folder on your Desktop
Copy the contents of the DSi SRL Extractor .zip file to a folder on your Desktop
Navigate to /Private/DS/Title/ on your SD card
Copy the .bin file to your DSi SRL Extractor folder
Run the console_id.py file inside the folder
- This script requires WINE on Mac/Linux/*nix systems
When prompted, press Enter
Copy the new console_id.txt file to a safe location on your computer

Using TempNAND

Download and extract the TempNAND .zip file to somewhere on your computer
Open the TempNAND .jar file
- Make sure you have Java installed
Navigate to the setup tab
Select Console ID > get Console ID from file
Select your console_id.txt file from earlier
Select CID > get CID from file
Select your CID.bin file from earlier
Select File > Open Encrypted NAND
Select your clean_nand_dsi.bin file from earlier
- This might take a few seconds
- If it appears to freeze, give it time
Select “Install Unlaunch”
Select unlaunch.dsi from the Unlaunch .zip you extracted earlier
Select File > Save As
Save a copy of your NAND backup for later use
Rename it to unlaunch_nand_dsi.bin
Select File > Save for No$GBA
Save a the file to the NO$GBA folder
Rename the No$GBA NAND backup to DSI-1.mmc

Testing NAND

Open No$GBA
Select Options > Emulation Setup
Set “Reset/Startup Entrypoint” to “GBA/NDS BIOS (Nintendo Logo)”
Set “NDS Mode Colors” to “DSi (retail/16MB)”
Select Save Now > OK
Select File » Cartridge Menu (FileName)
Open the .nds file

Your NAND should now be emulated by No$GBA. If it does not work, the NAND backup is not safe to use and it is not safe to flash it to your DSi.

If the backup works in No$GBA, feel free to continue to the next section.

Reflashing NAND

Copy the unlaunch_nand_dsi.bin file back to the folder on your SD card created by fwTool
Delete the nand_dsi.bin file on your SD card
- Make sure you still have the original backup on your computer!
Rename unlaunch_nand_dsi.bin to nand_dsi.bin
Open the Flipnote Studio application
- Ensure that the booting to Calendar mode is disabled in Flipnote Studio’s settings
- If you already have another DSiWare exploit installed, open that and skip to Step 16
Select View Flipnote > SD Card > Select Folder > User > ugopwn
Click on the note with the red bottom half
Select “Edit”
Click on the Flipnote frog icon in the bottom left
Click on the film roll icon
Select Copy > Back > Exit
Click the second note.
Click on the Flipnote frog icon in the bottom left
Click on the film roll icon.
USA/EUR/AUS: Click on the single right arrow (the next to last arrow icon) two times
- You will see a new frame be created
Based on your region, do the following:
- USA: Click on the paste button exactly 122 times.
- EUR/AUS: Click on the paste button exactly 2 times.
- JPN: Click on the paste button.
USA/EUR/AUS: Select “Erase” and then “Paste”
- This will launch HBMenu
Navigate to fwtool.nds, and press (A)
- fwTool will appear
Select “Restore nand_dsi.bin”
- This will take a few minutes
After it has finished, power off your console

With Unlaunch installed, your system now has primitive brick protection, unless the launcher’s TMD file is destroyed. Unlaunch has protections that should prevent this from happening, and HiyaCFW uses your SD card as the DSi’s NAND, adding a very resilient layer of brick protection.
