I have seen a thread in this forum telling you how to save a brick in QHSUSB_DLOAD mode.
Of course it didnt work, he said it was for the Moto X, Your phone is Hard Bricked and there is no way to recover it unless you send it in for Jtag Repairs.
sorry man it happens, i have hard bricked 4 phones before, just gotta be careful and read all the directions and make sure you download the correct things.
