Turn of your phone.
Open SUS.
Next then read read
choose phone XPERIA U
Connect plug to computer . do not plug to phone now
then press the volume down button and plug the cable in phone at the same time.
keep holding
IF successfull green light will light at the bar. IT WILL ONLY LIGHT HALF SO YOUR PHONE IS NOT DEFFECTIVE.
You are good to go. Read and next next.
