Please don't put personal contact details on public forums for your own protection.

If the phone failed to power on after an update you may have run the battery flat.

Use only the factory charger. Plug in and wait several hours for the chip in the battery to "wake up." When it does the phone will boot and start taking a charge normally.

Side question: Did you remove the SD card before applying the update? You should.
