That sounds like the APU was working but the APU bleed air was not. It is the APU generator that is needed for ETOPS, not the APU's bleed air.
The 767 RAT is only used if both engines fail. It provides hydraulic pressure to operate the flight controls. (I flew the 757/767 briefly at a previous airline). Here's a picture of a deployed 767 RAT in the maintenance hangar. Not a UAL airplane or hangar but it would look the same.
