Stuck in blackscreen topic

Erm guys, I've pulled out my LGOG out of the cupboard after about 6 months. Now, when i plug in the charger, the LG logo shows up for a brief moment, and the phone is now stuck in a black screen.

I am trying to hard reset the phone by pressing Power + Vol Down but they dont seem to be responding.

Before my LGOG went into the cupboard, I unlocked it using FreeGee. People were saying that the phone should never be turned off.

I hope you guys can help me :P, or i will just dump this phone back into the cupboard...

Thanks
