Do you want to install cias on sysnand or emunand?
The easiest way on 9.2 and under is to use Dev Mode, under rxtools' advanced options (this is equivalent to running PastaCFW), then opening homebrew again and loading a .3dsx of FBI, which you'll use to install a .cia version of FBI.
Then you can (backup the SD and) create emunand, which will start with a fully functional CIA manager!
