Note, After installing the Play Store apk, you might see the message ” Unfortunately, Google Play services has stopped ”
At this point, please perform a “Factory data reset” from the settings menu.
Once completed, the Play Store will function normally.
If you encounter a message telling you that your device is not Google Certified, you can still install Google Play but you must first register the device. Below is the process.

Find your device’s GSF Device-ID. There’s a simple app on the Play Store called ‘Device ID‘ (https://play.google.com/store/apps/details?id=com.evozi.deviceid), but since you obviously can’t access the Play Store I have mirrored the application here (https://www.androidfilehost.com/?fid=673956719939830832).
Open the app and copy the code in the second line called “Google Service Framework (GSF).”
Go to this webpage (https://www.google.com/android/uncertified/).
Enter your GSF Device-ID in the “Android ID” box.
After you tap “Register”, your registered ID should appear on the page.
Complete the process and click Ok at all prompts that require.
Reboot the device.
Occasionally there is a bug that forces you to have to repeat the registration process one more time.
