My Sony Xperia Z won't start /turn on after failed update attempt

When I plug the phone into the wall charger, the LED comes on red, the SONY logo appears on my screen, followed by a message indicating that "The Software update failed. Make sure that your phone is connected to the computer and try again.", and then the phone turns itself off. The cycle repeats itself with no indication that my phone's actually being charged.

Fully switch off your phone and make sure it is disconnected from your Pc then start PC Compannion and select Support zone then Update my phone/tablet then in Blue select Repair my phone /tablet and follow the onscreen instructions and when prompted making sure your phone is still switched off hold Volume down and connect your USB cable which should enter your phone into flashmode and start the repair process

Re: My Sony Xperia Z won't start /turn on after failed update attempt

Sony Xperia Z is my business phone. It won't work now, due to the failure in the software update process. As far as I know, I can't restart my phone without losing my private data, including business contacts. This is the last product I will ever buy from Sony!
