You can reset the Zeki by Powering off. Then at the same time press the volume up button and the power on button, hold them until the Android splash screen pops up.

I'm assuming it is the Zeki 8" TBDG874B. What I would do to get it of the flashy Android logo is hold down the volume button on the minus (-) side and get a small pin or needle to tap the reset. While holding the volume it will reset, then tap the power button still holding volume it will bring up a list. Do a factory reset (you lose all data but that's what I would to do to be on the safe side).
