Update failed. Bricked phone. Help!! topic

Tried to update to latest firmware using Sony bridge for Mac and about 10 minutes in, I got an error message and a failed update.
Phone now stuck in bootloop with message telling me update had failed please connect to computer and try again...... Mac won't recognise the phone now though.

Anyone got any ideas?
I've tried holding volume up and power buttons for 10 seconds and tried charging.... but the phone got really hot.

Anyone???
