LG C800 (Hard Reset) Factory Reset:
When the phone is turned off, press and hold the
Power/Lock + Volume Down + Qwerty F + Qwerty A Keys at the same time (for over ten seconds). The
phone will turn on and 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.

I have an LG C800 that I bought and I have found out that it has an unlock password and I need to know if I can do a factory restore without going into the phone?
