is this bricked

im flashing a liteon using dosflash i made a homemade serial and extracted the keys and files everything seemed to go well. i then made a dummy bin verified it withdsdbfixer and made the hacked firmware after erasing. now before the flash i failed to power cycle. when i inserted a disc to test the 360 it wouldnt open it it just said opening. i then erased the firmware and rebooted and now the pc is not detecting my drive not in the post or in junglefalsher furthermore ive plugged everthing nback in and i get an e64 error and one red light
