Locked out of my Kids Tablet 7 inch touch screen Android 4.1

If your kid ends up forgetting his or her password here's a easy way to do a hard reset. Simply hold down the volume down button - not the + for about 10 seconds then hold the power button firmly til you see the boot screen logo a android picture fallowed by some options for reboot and recovery. scroll down using the volume keys and the power button or camera button as the "Enter" key. and about a minute you will be asked to do a factory reset of the device, it takes about 15 minutes to finish the hold recovery. hope this helps.

You did try to hold vol+ while powering on, and keep on holding vol+ until you get the menu?
