ROM Hack How to Install Pokemon X & Y ROM Hack?

[iForgot]

I want to install this http://www.pokecommunity.com/showthread.php?t=362505 ROM hack for Pokemon X and Y. I followed this tutorial, https://gbatemp.net/threads/tutorial-how-to-decrypt-extract-rebuild-3ds-roms.383055/ but I always get "The game card was removed". If you could tell me how to go about doing this, I would really appreciate it. I'm using RXTools and a Gateway.
