Xperia Z2 tablet bricked after firmware update

[bryan_g]

Hi

I recently did a firmware update and my Z2 tablet has refused to boot since.
The power button is unresponsive, the LED light isn't displayed when connected to the charger and the screen remains blank.

I followed the steps below and have been unsuccessful. Any help would be appreciated

To repair the phone software
1.     Install PC Companion on a Windows PC from Support
2.     In PC Companion, under Support Zone and click Start.
3.     Under Phone Software Update, click Start.
4.     Click repair phone.
5.     Follow the on-screen instructions.

Connect your phone to a wall charger > press and hold power & volume up for 10 seconds > let it charge for 2 - 3 hours > even if it doesn't show signs of life

I was prompted for an update this morning & device has been unresponsive. All the button combinations aabove & running PC Companion have not helped. Any other suggestions?
