Q7 Android TV Box Bricked - Unable to flash firmware due to "Download Firmware Fail" error

Hello,

I have recently purchase a Q7 Android TV Box from Geekbuying,http://www.geekbuying.com/item/Q7-TV...ck-324259.html
After pressing the recovery button on the back of the device it will no longer work, it only displays a black image and remains that way.
After searching through most of the threads related i have decided to flash the firmware .
I am using Rockchip Batch Tool v1.7 to flash the firmware.
The firmware is http://blog.geekbuying.com/index.php.../#.Uxp1C4UVAdE.
In order to enter recovery i plugged in the micro usb cable while holding the recovery button pressed. The square in the Rockchip Batch Tool turns GREEN and it recognise the device.
After that i clicked Upgrade/Restore. Eventually i receive the error "Download firmware fail " in Rockchip Batch tool, image below.

Tried other stock roms and custom roms specifically for my type of device, same error every time : ""Download firmware fail ""
What am i doing wrong? Can it be fixed or is it bricked permanently?
