Try the basic, force restart the phone > press and hold power & volume up for 10 seconds > charge your phone for 1 hour then try again 

if that doesn't work then 

run PCC > follow all the steps to repair it > turn off your phone > connect your Xperia S

Hi msd1986,

You may also want to try an alternative PC to perform the software repair on the device, as this may be related to the drivers on the PC other then the handset.

Let us know how you get on with the software repair.
