[Q] Bricked. Can't get computer to see OPO topic

My friend bricked his OPO, so I am attempting to fix it for him. I have came across the numerous fixes for bricked devices, although there is one problem I cannot seem to find a solution to. My PC does not see the phone at all. When I hold Vol down+ PWR I get nothing but a vibration every 2-3 seconds. No connect noise through my computer that it at least sees the phone or it doesn't pop up on the device manager. I only have a windows 7 computer.
