Default [Q] Lumia 920 bricked

Hello, my phone Lumia 920 was bricked and it doesn't boot up or respond to any of the input combinations(Vol up +power ) or ( Vol. down + power) it's just showing a black screen and when I connected it to a windows 7 pc it showed as (QHSUSB_DLOAD) and windows failed to install drivers for it I searched online and I reached the Qualcomm drivers for (QHSUSB_DLOAD) mode and now the device is readable as (Qualcomm HS-USB QDLoader9008) in the Ports(COM & LPT) section in device manager and can't do anything beyond that ... any help on how to recover this state to a normal working one using any method even if on a Linux based system computer? I need real help
