Wifi and Google Play access after factory reset for off contract Sprint HTC Evo 4G
A factory-reset deletes all the user data. It's as if you had a brand-new tablet (but any system updates you've previously installed will still be there).

This means the tablet won't have the password for connecting to your Wi-Fi network, nor the password for your Google account. The first time you turn it on, it will take you through the same initial setup process as when it was new: it'll prompt you to connect to a Wi-Fi network and log into a Google account. If you log in with the same Google account as before, it'll still be able to access all the apps (and books, music, films, etc.) you previously installed/bought from Google Play
