ROM Hack Compiled cia/3ds game doesn't boot.

[XDM]

I'm sure you heard this plenty but I decrypted a .3ds rom and unpacked it and then i recompiled the . 3ds and places it on my gateway. But it shows a white square instead of the game icon and said that there was no game cart inserted.

And another game I decrypted it and directly converted to cia and the game is installed but when I launch it it says a error has occurred, hold power button.
I'm using a 3ds to cia converter 4.1

where did you get the .3ds rom file? Also do you have homebrew?
