This should do the trick,
1)Make sure the tablet is NOT connected to the charger
2) Power off the tablet by holding down the power button for about 10 seconds
3) Once it is off, hold down the HOME button and connect the charger while the button's being held down.
4) When you see the HKC logo come up, let go of the HOME button.
5) Eventually, you'll see an Android logo with a red exclamation mark. If you don't, repeat step 3-5.
6) If you do see the Android logo, hold down the POWER and HOME at the same time for one second and just let go of the HOME which should bring up a "Recovery mode" menu with blue letters. Make sure you let go of the POWER button as soon as you see the menu pop up, otherwise your tablet will just shut itself again.
7) Navigate to "wipe data/factory reset" using the HOME button and select with the POWER button.
8) Navigate to "Yes - delete all user data" and select it.
9) Once it's done, you should see the menu come up again. Navigate to "Wipe Cache" and press the POWER button
10) It should take you back to the recovery menu. Simply press the POWER button while highlighted on the "Reboot system now"
