I did a reset on my zeki 8 inch screen,now its stuck on the main meep tablet screen,can you help?

The answer depends on what you wish to do. The reset button on the back of the Meep will get you out of a stuck application. To remove all content from the tablet, you'll want factory reset which you perform through the Settings menu. The reset button does not remove content or return the tablet to factory state.

Go to this site for the instructions on how to do a hard reset on your tablet.

Reboot to factory settings.

You will need to reset your tablet Zeki Tablet. To do it, make sure your tablet is fully charged then press and hold the volume button. Tap reset and continue holding the volume. Go to http://www.zekitablet.com/zeki-support.html for details.

Resetting is unlikely to resolve a power issue if it truly can't turn on... if that is the case, you could talk to an OSI call center. If it just gets stuck on the startup screen, you can try the reset on the back or rebooting... neither of which will erase anything. A factory reset would remove content, but if you can't get it to boot up, you can't get to the Settings menu to run a factory reset. If you did run one, all content is recoverable in the Meep Store

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).

For the power button, you'll need to contact the OSI call center. For the other, a factory reset through the Settings menu may resolve it.

There are two things you can try for this. The first is to reboot the tablet using the power switch. The other is to press in the Reset button on the backside of the Meep. If neither of these helps the situation, you'll want to contact the OSI call center.
