Charge your phone for an hour > on your PC > run PCC > follow all the steps > then try to update your phone once more

The phone has to be turned off 

PC Companion (PCC)

Bridge (for Mac)

Performing a system repair using PC Companion - This will factory reset your phone and erase all data

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 on screen 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

Yes so disconnect your phone from the Pc then when prompted hold volume down and reconnect your USB cable then the process should begin

Nothing happened , have disconnected the usb cable and waited for 5 seconds then reconnected the usb cable and held volume down button till led flashed a green light then off and nothing happened .

Odd, what if you press and hold the volume up before you connect it to the computer, you could also restart your PC and try again.

Open your Device manager and connect your phone in the way mentioned - Do you have a missing driver?
