google verify your account this device was reset

I won a Samsung Galaxy S6 Edge, signed into it with my Google account, played around with it, wiped it, and sold it.

Now the person can't get past setup because it's saying he must login with an account previously synced to the phone.

Is there anything I can do from my side to remove this lock?

当出现 这个界面的时候 打开cmd

用手机连接上usb, 使用下面命令

adb shell am start -a android.settings.SETTINGS

打开设置，  Backup & reset -> Factory data reset -> Reset PHONE -> ERASE EVERYTHING;

再重新启动就不会再有上面的问题了。
