For those who didn't read in between the lines....
Instructions on how to wipe the phone clean:
1. Turn of Phone
2. Hold Volume Down+Home key+Power button
3. Enjoy your resetted phone
This can be found in the instruction manual which you can download from LG support.
Note: This is for people that have not messed with their recovery, if you have installed custom recovery, you cannot factory reset, but you can flash an entire custom ROM.
Ok, you want help? I am here to help. But if you can't read, I can't really help you.
Why on earth would anyone help someone who does not read? This is a forum, the purpose of it is to read.
