Re: unable to unlock my lumia 720

Perhaps your only way now would be to use the Windows Device Recovery Tool or do a hard reset with the key combinations :

1.At the very beginning turn off the phone by using the Power button.
2.In the next step hold down the Power key until the device vibrates.
3.Then press and hold the Volume Down button until you see the exclamation point on your screen.
4.Now, you can release all keys.
5.Press the following sequence of buttons: Volume Up - > Volume Down -> Power - > Volume Down.
