[AC Question]

I have no details. My son was fooling around with it and it shut down, never to restart again, I'm afraid. I am not a techie, so I need an EASY fix. I've taken the battery out and put it back, but that's all. I need help, fast! Anybody?

You would need to do a factory data reset which will result in you losing all the data in the phone and returning it back to "factory condition".
Hold the Volume Down and Power button together for a couple of seconds and when the LG logo is displayed, keep pressing the Volume Down and then press the Power button.
When the factory data reset page comes up, select yes using the Volume button followed by the power button.
If even this method fails, you would need to flash back the stock image which can get a bit tricky, but you can always revert to this forum!
