Thanks a lot.FWIW, this is a destructive operation and will wipe all your data.
power off the device
hold the power and volume up simultaneously until you get to the recovery screen.
use the volume up and down to select "wipe data / factory reset"
use the power button to select the option.
This should reset AP200. But this will reset the language back to Chinese. Before doing make sure you know the operation to choose your preferred language once it reboots. If you still have a firmware download there is a file called "System Language Settings.pdf" that has pictures to help out.
I did exactly that, everything completely wiped. After clean install, changed the language from Chinese to English. Still when trying to make new login to Google Play Store, getting the same error message "Unfortunately, Google Play Services has stopped".
