feature will only be available if and when LG makes a newer firmware version

and notes that appear at each step before proceeding. Please note that removing
the USB cable during the upgrade may seriously damage your mobile phone.

models at its own discretion and does not guarantee the availability of the newer
version of the firmware for all handset models.
