ZEKI Root Custom Roms Recovery

on Zeki Tablet you had to hold both the "Reset" button and the "volume up" button at the same time for about 15-20 seconds it than boots into Safe Mode which you can select a full factory reset. NOT VOLUME DOWN.

If this fails, 1 888 999 4215 is Zeki support. If in warranty, tell them of failure of factory reset. They may request it be sent to them.

Factory reset!!!!!!

You will need to backup your stuff and then do a factory reset.

Then download the latests updates before putting your stuff back on.

Look on the back where the jack is for the charger. Observe the symbol of the charger plug. There will be a + or - on the center pin. Match the charger with the tablet BEFORE you connect it.

You can try a factory restore, but if that doesn't work you will need to buy a new tablet. These cheap tablets are throw-aways unfortunately. Note that a factory restore will erase any files you have on the device.

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).
