Xperia Z3 Compact Software Update - Won't Power Up

[BrokenPhone9999]

I received an update to my Xperia Z3 Compact this morning which I installed using the update centre. Now my phone will not switch on. I have tired resetting it, and it will just not power up any longer. There was planty of battery life, and I have also tried connecting to the mains again. When doing this, it doesn't even come up with the charging symbol. Anyone have any ideas how I can sort it out?

Try performing a system repair using Pc Companion as this will often fix issues - This will factory reset your phone

Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)
Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the onscreen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process

If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP

Sorry it's taken a while to get back, but just back from work.  The phone is already off.  When I start PC companion and connect the phone, the phone doesn't get picked up by the PC.  I think this is because it just isn't responding at all, even when I press the small yellow reset button.  Not sure if I'm missing something?

Connect the phone to a wall charger > press and hold Power & volume up for 10 seconds >let it charge for 2 to 3 hours

OK, have done that.  The phone didn't do anything, but have left it plugged in and will see what happens in a few hours.
