5. Using the hard reset
If it does not restore to the original condition,
use hard reset to initialise your phone.
When the phone is turned off, press and
hold the Volume down key + Power key
for over ten seconds. When the screen
shows the LG logo, release the Power key.
After the screen shows the hard reset
screen, release the other keys.
Leave your phone for at least a minute while
it performs the hard reset, then your phone
will be turned on.
Caution: If you perform a hard reset, all user
applications and user data are deleted. This
cannot be reversed. Remember to back
up any important data before performing a
hard reset.
6. Connecting to Wi-Fi networks
To use Wi-Fi on your phone, you need to
access a wireless access point or "hotspot."
Some access points are open and you can
simply connect to them. Others are hidden
or use security features; you must configure
your phone to be able to connect to them.
