9. Using hard reset
If your phone does not restore to the original
condition, use a Hard Reset (Factory Reset) to
initialize it.
When the phone is turned off, press and hold the
Power/Lock Key + Down Volume Key .
After 5 seconds, keep pressing the previous keys
and touch and hold the Menu Key + Back Key
(must be done before the touch key LED lights turn
on). When the LG logo appears, release the Power/
Lock Key but keep pressing the rest of
the keys. The phone will perform a factory reset
immediately.
WARNING: If you perform a Hard Reset, all
user applications, user data and DRM licenses
will be deleted. Please remember to back up
any important data before performing a Hard
Reset.
