If you didn’t hear about this exploit yet it is a qrcode based primary exploit just like Cubic Ninja. It’s the only working primary exploit on Firmware 11.0 for now. The base game needed is Freakyforms Deluxe.
1. Get the latest version of freakyhax, and extract it to the root of your sdcard.
2. Get the “otherapp payload” for your 3DS firmware from the homebrew launcher website.
3. Put the otherapp bin on your sdcard root and rename it to “otherapp.bin”.
4. Get the homebrew starter kit from the homebrew launcher website and put it on your sdcard.
5. Start the game.
6. In the game menu pick: Play → Camera → Load a QR code → pick the image.
It should be installed now and work perfectly. If not you can found troubleshooting steps here
Thanks to Qlutoo for providing the exploit.
