You have to reset it to factory default just follow those steps:
1. shutdown the tablette
2. hold volume up button and press the power button
3. when manufacturer logo come realise the power button but keep hloding the volume button to get into recovery mode
4. in recovery mode use volume up/down button to navigate and the power button to select
5. choose WIPE DATA / FACTORY RESET than select YES .... wait a moment then select WIPE CACHE PARTITION
6. finale step select REBOOT
keep in your mind the all data in the phone will be erased (apps & games)
ALL DONE!!!!

well that happened to me but i went on this website where you can reboot the whole tablet to take off the password and it still keeps all the data you stored on the tablet.

its brand new and you forgot everything already if you did the google mail password assist then open that if dont know that or didnt do it can try provider for assistance and most lockouts are either 1hr or 24hr

You do not need gmail.com only tap on SETTINGS to factory-reset your tablet.
