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

1. Connect your tablet to a wireless network.
2. Download and install the Android version of the Netflix app from the Play Store.
3. If you have a subscription to Netflix, open the app you just installed and enjoy ! Otherwise, subscribe to Netflix and then do Steps 1 and 2.

Hope this helps.

You need to do a factory reset!

1. Make sure your tablet has a full charge
2. Press and hold the Volume - button and tap the Reset button
   (The reset button is located between the HDMI and USB ports)
3. Continue holding the Volume - button until the boot screen appears
4. Release the Volume - button
5. Use the volume controls to navigate to "Wipe data/Factory reset"
6. Press the power button to select
7. Navigate to "Delete all user data"
8. Press the power button to select

Your tablet will take several minutes to reboot to a factory default setting.

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).

what format is the file your trying to open in? (i.e. .doc,.pdf,.jpg)
