How to unlock lock screen Pattern On lg g2

I can't unlock my lock screen, I watched some videos on YouTube and it said to reboot the device I tried to by pressing the power button and down volume button the lv icon came on then pressed the power button then the up button and nothing. Anyone have any suggestions on how else I can unlock my phone? Thanks.
