Here you go. There are a few things I need to mention and a few things you need to do.
1. In the zip file attached to this post, there are 3 files. The payload, a boot.3dsx, and a hbll.3dsx. The boot.3dsx is from the latest Luma3DS release. The hbll.3dsx is for the Homebrew Launcher loader CIA.
2. I've hex edited the payload to recognize the hbll.3dsx file so that you can launch the Homebrew Launcher loader CIA.
3. The boot.3dsx will allow menuhax to autoboot into your EmuNAND.
The steps:
1. Replace the payload on her SD card with the payload in the zip file attached.
2. Replace the boot.3dsx file with the one in the zip file attached.
3. Add the hbll.3dsx file to the root of her SD card.
Through this, you should be able to autoboot into your Luma3DS EmuNAND through menuhax and be able to launch the Homebrew Launcher loader CIA on your EmuNAND. Let me know if this works!
