3DS:System Transfer/Target has CFW

The system transfer process is mostly the same as it would be done without CFW on either device, but you will need to use faketik at the end to restore any applications and games that did not come from the eShop.

What You Need

• The latest release of GodMode9 (the GodMode9 .zip file)
• The latest release of faketik (the .3dsx file)

Instructions

Section I - Prep Work

• For both consoles, perform the following steps:
  1. Power off your device
  2. Insert your SD card into your computer
  3. Copy GodMode9.firm from the GodMode9 .zip to the /luma/payloads/ folder on your SD card
  4. Copy the gm9 folder from the GodMode9 .zip to the root of your SD card
• Reinsert both SD cards into their respective consoles

Section II - NAND Backup

Creating a NAND backup of both consoles is a good idea in case something goes wrong. It ensures you can recover your data in the event of an error.

• For both consoles, perform the following steps:
  1. Press and hold START, and while holding START, power on your device. This will launch GodMode9
  2. Press HOME to bring up the action menu
  3. Select "Scripts..."
  4. Select "GM9Megascript"
  5. Select "Backup Options"
  6. Select "SysNAND Backup"
  7. Press A to confirm
     • This process will take some time
     • If you get an error, make sure that you have at least 1.3GB of free space on your SD card
  8. Press A to continue
  9. Press B to return to the main menu
  10. Select "Exit"
  11. Press A to relock write permissions if prompted
  12. Press R+START to power off your console
  13. Insert the console's SD card into your computer
  14. Copy <date>_<serialnumber>_sysnand_00.bin and <date>_<serialnumber>_sysnand_00.bin.sha from /gm9/out to a safe place on your computer, then delete both files from the SD card
  15. Reinsert the SD card into its console

Section III - System Transfer

1. Perform the system transfer as usual. If you are transferring from a Old 3DS to a New 3DS, choose the option PC-Based Transfer when asked, not Wireless Transfer or Low-Capacity microSD Card Transfer
   • The prompt mentioning this is not given when transferring between two Old 3DS consoles or two New 3DS consoles. These transfers are almost the same as PC-Based Transfers, but ask you to move the source console's physical SD card to the target console rather than just copy the data over. This part can be ignored without consequence, and you can copy the data between the SD cards anyway
   • If you have the option to pick a PC-Based Transfer but do not have access to a PC, be aware that during a Wireless Transfer, homebrew software, cartridge dumps, and any other data only obtainable through CFW will not be transferred over. You will need to take extra steps to reobtain the lost data.

Section IV - Homebrew Launcher

1. Launch the Download Play application
2. Wait until you see the Nintendo 3DS and Nintendo DS buttons
3. Press L + D-PAD DOWN + SELECT at the same time to open the Rosalina menu
4. Select "Miscellaneous options"
5. Select "Switch the hb. title to the current app."
6. Press B to continue
7. Press B to return to the Rosalina main menu
8. Press B to exit the Rosalina menu
9. Press HOME, then close Download Play
10. Launch the Download Play application
11. Your device should load the Homebrew Launcher

Section V - faketik

1. Launch faketik from the list of homebrew
   • If you receive the error "The External Title Database is not available.", ensure that the correct SD card is inserted into the console
2. Press HOME, then close Download Play

The transfer is complete! Note that you may have to unwrap all the icons that were restored by faketik.

Section IV - Homebrew File Recovery

This section will have you manually copy all homebrew files onto the target console, as wireless transfers actively refuse them.

1. On the target console, note all apps that should have appeared but are missing
2. Insert the source console's SD card into your PC, and copy the homebrew data off of it and onto your PC
   • Everything except the Nintendo 3DS and DCIM folders is considered homebrew data
3. Take out the source console's SD card but leave it out of its console, and insert the target console's SD card into your PC
4. Move all of the files you copied off of the source console's SD card onto the target console's SD card
5. Reinsert the target console's SD card into its console
6. Redo Finalizing Setup on the target console. This will ensure you have backups available in case the next section does not work as intended

Section V - Homebrew App Recovery

This section will restore all games/savedata that the Wireless Transfer refused to copy over.

1. Insert the source console's SD card into your PC and mount its Nintendo 3DS folder using ninfs
2. Copy all games/savedata that were not transferred onto the target console onto somewhere on your PC
3. Unmount the source console's Nintendo 3DS folder and reinsert its SD card into its console
4. Insert the target console's SD card into your PC
5. Mount the target console's Nintendo 3DS folder in ninfs, and add all copied games/savedata from your PC into the existing contents
6. Unmount the Nintendo 3DS folder from ninfs, but keep the target console's SD card inserted
7. Rebuild title.db on the target console to force all the new apps to appear
8. Reinsert the target console's SD card into its console

The transfer is complete! Note that you may have to unwrap all the icons that were restored.

Attempt to redo the transfer. If it continues to give errors, join the Nintendo Homebrew Discord and ask, in English, for help.
