The one that says Kitkat.SELinux Permissive init.d_by Walter.White aka Heisenberg.zip Walter.White aka Heisenberg init.d script (You need this to automatically boot phone in permissive mode))
KitKat_init.d_Support_ALEXNDR.zip You only need this if you do not have init.d support (most custom roms come with init.d support)
UPDATE-SuperSU-v2.13.zip this is to update your SuperSu (to get permisive to work)
Second script?
