Fixing root on Nexus 5X

It seems Secure Settings does not work with systemless root. I use Secure Settings along with Tasker to automatically set my phone on airplane mode when I am connected to wifi.

I use Project Fi for cell service which supports wifi calling and texting. Disabling the cell modem while I great wifi signal saves around 10-15% of my battery everyday. It is especially helpful at work because of the lack of cell service where I sit.

I found the following commands here in a reddit post. Warning: these commands may prevent Android Pay from working.

Run the following commands to fix Secure Settings. I used a terminal emulator on my phone. You can also run them from within a abd shell from your computer.

su
mount -o remount,rw /system
touch /system/bin/su
mount -o remount,ro /system
reboot
