My z1 shut down on its own with half battery and wasn't doing anything special just texting and facebook. It wouldn't turn on so did a hard reset and it came on, i plugged it into the computer to see about any updates to fix it. It started to do an update then turned off again and will not turn back on even after a hard reset, when on charge it repeatedly turns on, the sony logo appears then says, software update failed. make sure your phone is connected to a computer and try again. i plug it into a computer and nothing happens at all not even the repeated message. Any ideas, have i done something wrong, i only had the phone a couple of weeks what a letdown.

press and hold power & volume up until the phone is off then connect it to a wall charger for 40min or so > repair it with SUS > do not turn on your phone, also remove the SIM and SD cards
