I need to unlock my son,s noria jr.tablet! he forgot the password,since December! CAN YOU HELP?

Since it's not on a Network it basically impossible. I'd reset to factory defaults and start over. I'd first takes out any memory card and the hold down both the power button and the volume up and when the Samsung logo appears hit hte volume down button and you should geta menu that includes the wipe data and factory reset option. Use the volume button to select it and then the home button to activate it and then select yes and use the home button. The just be patient and it will eventually rest.
