In terminal emulator writ
mount -o rw,remount,rw /system
mount -o ro,remount,ro /system
Thats it .....
You forget reboot command at the end.
However it works with my stock rooted note4. And now unicon granted superSU and I can open it and choose the icon pack, but after apply the choosen icon pack and restart launcher and apps or full reboot nothing changed!!! the icons theme still on stock!!! I did everything but the issue still exist.. the icon packs doesn't apply even after that popup message (icon applied) appears!!!
