Filesystem /etc/ write-protected

[tomrow]

I can't disable kiosk mode due to a write-protected partition, how can I enable writing to chrome_dev.conf?

[fydeos-alpha]

do this:

sudo mount -o remount rw /

Then you will have read-write access of /.

I have managed to do the following steps but still something is wrong or missing;
Step 1 = CRTL+ALT+T - this will open the Crosh window
Step 2 = use the command: shell ( this will open the shell )
Step 3 = use the command: sudo mount -o remount rw / ( this will give you the writing rights )
Step 4 = use the command: sudo vi /etc/chrome_dev.conf ( this will bring you to the file you want to edit )
Step 5 = add the line: --force-kiosk-mode
Step 6 = press Esc
Step 7 = type: :wq! ( and then press Enter)
Step 8 = sudo reboot

So far this has not given me the result I am looking for. Can someone indicate what I should change ?
