How to Factory Reset Your Android Phone or Tablet When It Wont Boot

You will lose all your personal data... but the only thing I can think of to do for this is to do a factory reset. To do that you have to hold down the start button and the volume button until it comes on and gives you a menu. Then navigate from there.

Go get yourself a bigger card too. 8mb is way too small.

Usually you have to reset the unit. Try turning off the power then press the power button for about fifteen seconds then let it go and see if this solves the problems.

Turn it off completely. Either by reset or shutdown.
Leave it off.
plug in charger and leave it alone for 4 hours.
Power it back on.

did you buy it from a reliable source? lots of bad tabs and "pads" being sold online lately. might be bad internal power source. suggest take it to local dealer and let them troubleshoot, take the advice then fix yourself if you are good with electronics, or let them fix it or trade it in.
