If you did not get your problem resolved, I would check OS. No success under 10.11.3 but 10.7.5 worked. Remember to have the Apple 5.1 firmware update mounted as well (and not the B07 firmware like some idiots did. like myself)

HI, Coming very late to this, but I have exactly the same issue. May I ask how you resolved it? Thanks in advance
