The version of autofirm used in this guide was modified from [Reboot.ms](https://www.reboot.ms/forum/threads/2403/)'s autofirm which was modified from '[Raugo](https://gbatemp.net/members/356694/)'s original autofirm ([with permission](http://archive.is/KOrWp)).

#### Instructions_
|
||
|
|
|
||
|
|
##### Section I - NAND modification
|
||
|
|
|
||
|
|
1. Extract the autofirm zip to a folder called `autofirm`
|
||
|
|
2. Place a copy of your NAND backup (named `nand.bin`) in `/autofirm/` folder
|
||
|
|
3. Copy the contents of the NFIRM zip to the `/autofirm/source/firmwares/` folder
|
||
|
|
4. Run `autofirm.bat` and select which device and version the NAND backup is for
|
||
|
|
5. Wait while the script runs
|
||
|
|
6. If everything worked, then your original NAND will have been renamed to `backup_nand.bin` and you will have a modified `nand.bin` containing the 10.4.0 NATIVE_FIRM
|
||
|
|
7. Flash this `nand.bin` to your device with your hardmod
|
||
|
|
|
||
|
|
##### Section II - Exploit verification
|
||
|
|
|
||
|
|
1. Copy and merge the `3ds` folder from the 3DSident zip to your device's SD card
|
||
|
|
2. Reinsert your SD card into your 3DS
|
||
|
|
3. Use [Homebrew Launcher (No Browser)](homebrew-launcher-(no-browser)) to launch the homebrew launcher on the device
|
||
|
|
4. Launch 3DSident
|
||
|
|
5. Verify that the following:
|
||
|
|
+ **Kernel version**: 2.50-11
|
||
|
|
+ **FIRM version**: 2.50-11
|
||
|
|
+ If either of these do not display the versions above, something has gone wrong and you should try again from the beginning
|
||
|
|
|
||
|
|
Your version number will *not* have changed in the settings.
|
