For those having issues editing their build.prop in Marshmallow,or other system files

As ive been reading about this very much lately, after people have flashed Marshmallow and rooted, many are having issues editing their build.prop files. And many arent having any issues at all. Well, the fix is rather easy. You are going to have to change your SElinux to be permissive. Many that arent having the issue is because they are either using a custom kernel that has set SElinux to be permissive, or are using an app to change it. I use an app, dir viper4, because it needs to gave SElinux at permissive. There arent any apps that do it in the play store, because google removed them. But.. theres a site called xda that somebody is posting their SElinux changer app in ;) http://forum.xda-developers.com/show....php?t=2524485
