Edited @PaulKinlan 's gist.

Changes

• With set -e when something fails, whole script fails.
• When something fails, demo mode will be reverted on the device.
• Broadcast related outputs are sent to /dev/null
• Show Touches developer option will be enabled automatically.
• When it finishes, the mp4 file will be located in Finder.
