I am using the Nexus 4 with UbuntuTouch installed.

I switched to a writable filesystem by this command:

sudo mount -o remount,rw /

and it worked perfectly.

How to switch back correctly to read-only filesystem?

Where rw is read-write, ro is read-only:

sudo mount -o remount,ro /

See man 8 mount.
