# Script to wrap phablet-flash

#

# Script does the following:-

# * Backup (cookies etc) but not photos/videos

# * Flash device (via phablet-flash)

# * Add applications from collections PPA

# * Restore data

# * Reboot

#

# Assumptions:-

# * Device already running some build of Ubuntu Touch and is connected via USB

# * You're on Wifi and want the device to be on the same Wifi network
