### Required Reading
Note that if you have any payload files other than `GodMode9.firm` in the `/luma/payloads/` folder on your SD card, holding (Start) on boot will display a "chainloader menu" where you will have to use the D-Pad and the (A) button to select "GodMode9" for these instructions.
To use the [magnet](https://wikipedia.org/wiki/Magnet_URI_scheme) links on this page, you will need a torrent client like [Deluge](http://dev.deluge-torrent.org/wiki/Download).
To extract the `.7z` files linked on this page, you will need a file archiver like [7-Zip](http://www.7-zip.org/) or [The Unarchiver](https://theunarchiver.com/).
If you do not use the correct `.firm` corresponding to the target 3DS, you will BRICK! Ensure you download and use the correct one!

Use a [save manager](https://github.com/FlagBrew/Checkpoint/releases/latest) to backup any saves you care about on *the target 3DS* (it will be formatted!)
+ The 8 Character ID will be the one from the [Installing boot9strap (DSiWare Game Injection List)](installing-boot9strap-(dsiware-game-injection-list)) page
1. Navigate to `content`
1. Press (A) on the `.app` file in the folder

+ The 8 Character ID will be the one from the [Installing boot9strap (DSiWare Game Injection List)](installing-boot9strap-(dsiware-game-injection-list)) page
1. Navigate to `data`
1. Press (A) on `public.sav`
1. Select "Mount as FAT image"
1. Press (B) to go back to the main menu
1. Navigate to `[0:] SDCARD`
1. Press (Y) on the file(s) in the `savedata` folder to copy them
+ If there is a `savedata` folder inside of the `savedata` folder, it is not by mistake. You should copy the second `savedata` folder, not the files inside of that.
1. Press (B) to go back to the main menu
1. Navigate to `[7:] FAT IMAGE`
1. Use the (X) button to delete everything inside of `FAT IMAGE`
1. Press (Y) to paste a copy of **the contents of** the `savedata` folder to `FAT IMAGE`
1. Select "Copy path(s)"
1. Press (A) to unlock image writing, then input the key combo given
1. Press (Start) to reboot **the source 3DS**
1. Launch your DSiWare game on **the source 3DS**
1. Tap the screen or press any button to start the game and test if the save is functional
+ If your game has an error about `boot.nds` or a white screen, **then the exploit has been successful**
+ If your game has an error about corrupted or inaccessible save data, confirm that you copied **the contents of** the `savedata` folder and not the `savedata` folder itself
+ If your game behaves normally and does not give you an error about `boot.nds`, then you should stop and figure out what went wrong
+ If you get a black screen, [follow this troubleshooting guide](troubleshooting#dsi--ds-functionality-is-broken-after-completing-the-guide)
#### Section III - System Transfer
1. If **the target 3DS** has a Nintendo Network ID on it, you must format the device using System Settings:
+ Go to the last page of "Other Settings" and select "Format System Memory", then follow all instructions
1. Read the following:
+ Your CFW 3DS = the source 3DS = "Source System"
+ Your Stock 3DS = the target 3DS = "Target System"
+ **Move DSiWare titles if prompted!**
+ Do **NOT** delete the source system's SD card contents if prompted
+ Make sure neither device's battery dies during the transfer
+ **Old 3DS or Old 2DS (source) to New 3DS or New 2DS (target) only**: if asked which method you wish to use to transfer the SD card data:
+ **Do NOT** choose the "Low-Capacity microSD Card Transfer" or minimal option (option 2), it will only transfer tickets and likely will not transfer the DSiWare save.
+ Fast Method: If you have the ability to move the data from the SD card (source) to the microSD card (target), when prompted use the "PC-Based Transfer" option (option 3).
+ Slowest Method: If you don't have the ability to move the data on a PC use the **full** "Wireless Transfer" option (option 1).
1. Go to [this link](http://en-americas-support.nintendo.com/app/answers/detail/a_id/227/) and follow Nintendo's official instructions for System Transferring from one system to another while keeping in mind what you just read
#### Section IV - Restoring the source 3DS
1. On **the source 3DS**, complete initial setup
1. Do one of the following
+ Do the rest of the sections and then the full guide on **the target 3DS**, then wait one week *(do not restore your NAND backup before system transferring)*, then System Transfer from **the target 3DS** back to **the source 3DS** *(remember you cannot transfer back from a New 3DS or New 2DS to an Old 3DS or Old 2DS)*
+ Call Nintendo and tell them you no longer have access to the device that your NNID is linked to (which is **the target 3DS** in this case), and would like it linked to a different device (which is **the source 3DS** in this case)
+ You can also just [remove the NNID](godmode9-usage#removing-an-nnid-without-formatting-your-device) from **the source 3DS** if you'd prefer it remain on **the target 3DS**
