Reset the phone to factory settings:
Tap on Settings --> General Management --> Reset --> Factory Data Reset
We will not be managing the phone with Meraki any longer so set the phone back up again like you would set up a personal phone. When asked to sign in, use a NON-GCISD Google account. If you don't have one, you can create a free account. This will be a personal account and will allow Duo and other apps to be downloaded from the Google Play Store.
You can now begin configuring your phone setting to your preferences.
