Im trying to import pictures from a usb onto my tablet

tablets use the charge port as a usb extension
try using a usb connector from the usb stick plugged into the charge port

try a windows emulator app on your android, leave it as it is but play windows games on it
see link below

Norton Norton Security antivirus Android Apps on Google Play AV for Android

you have to go to your home computer and go to google.com and reset your password then login to Google on your tablet you should be ok

You did try to hold vol+ while powering on, and keep on holding vol+ until you get the menu?

Try to reboot it

Try going to system settings and select 'About Tablet' then checking you are fully charged and in good wifi signal select 'system updates' Update to any new version it finds.
Make sure it is fully charged with the screen brightness down (so it will last for hours, just in case). The last thing you want is a power down during an update...
