Build.prop mod's for battery-saver/performance/signal/KNOX disable/SELinux disable

All users mod your own Build.Prop
(brequire Eng. Kern. (But that can be removed later))
Use this Kern. N920A_RootKit.7z

Method:
Connect Device (N920*) Works on all model SM-N920's
Odin Egn. Kern N920A_RootKit.7z
Open CMD and navigate to your ADB folder
Type in CMD the following:
adb devices (Make sure device reads)
adb shell mount -o rw,remount /
adb shell mount -o rw,remount /system
adb shell setenforce 0
adb pull /system/build.prop (The file will save in your adb main folder)
make a directory in adb folder name it prop
make a copy of the build.prop file and move it to the prop folder
Edit your build.prop file in the prop directory using whatever editor you choose.
(I use EditPlus.) Add OR edit the following of your choosing
Remember not to close your CMD YET!
