Re: problem with unlocking the screen on experia S
no other suggestion other than try unlocking it using the gmail account, make sure your data connection is working over your device and log yourself over the gmail account, goto the android device manager and try unlocking your device from there !! I am sure this is going to work out if you device has an active data or wifi connection. Other wise I am afraid but you've got no other option than moving forward with factory resetting your device.
