Welcome to Android Central! You're in Download Mode -- to get out of it, press and hold Power and Vol Down for about 20 seconds to force a shutdown, then power back on normally. Or were you trying to get to Recovery Mode?

How did your nephew change your PIN? Can you ask him what it was? FYI, it's pretty much impossible for a young child to change your PIN, because they'd have to navigate to the Security part of the system settings, select the menu to change the PIN, enter the existing PIN, then enter a new PIN, then re-enter the new PIN to confirm.
