B777 flight crew descended below the glideslope in vertical speed during an ILS approach. At 390 ft ...

Narrative:

Was left a little high on the glide slope (GS) by ATC when given the clearance heading 190; 2;500 ft; cleared ILS; 180 kts to the FAF. Abeam the airport we were presently flaps 5 approximately 180 kts. I put out a little speed brake to help the descent to 2500 ft so as to get on the GS. We intercepted the localizer a dot or more above the GS. The jet started to level at 2500 ft so I asked the first officer (first officer) to roll the MCP altitude down to 2000 ft. Putting the gear down would have helped but I didn't even think of it. At 2000 still above the GS the jet leveled. I reached over and rolled the MCP down to 00000 and in the same movement rolled it back up to something say that 'zero is allowed'. I told the first officer to set something so I could v-speed down. Got the flaps to 20 and lowered the gear late; 1400-1300 ft; landing checklist. But the speed brake was still out. From here we became totally unstabilized. Relief pilot (international relief officer) right aft seat called-out 'go around.....go around.' he said it twice because I didn't hit the toga switch and only pushed up the throttles so he couldn't see things happening and neither could I. I think I hit the autothrottles button; I did not hit toga so I had very conflicting info in front of me. Somebody yelled 'speed brake' and I pushed the speed brake lever down. That helped a lot! At some point I finally got it climbing with lots of coaching just via raw data. There was late gear retraction; and flap retraction. We kind of stabilized at 1000 ft; my first officer told me he reset both flight directors and got things cleaned up. I flew to 3000; the ma altitude and then flew to 5000 as cleared by ATC. At this point I gave the first officer the jet. We blocked in with 18.3 fuel remaining.

Narrative: Was left a little high on the glide slope (GS) by ATC when given the clearance heading 190; 2;500 FT; cleared ILS; 180 kts to the FAF. Abeam the airport we were presently flaps 5 approximately 180 kts. I put out a little speed brake to help the descent to 2500 FT so as to get on the GS. We intercepted the LOC a dot or more above the GS. The jet started to level at 2500 FT so I asked the First Officer (FO) to roll the MCP ALT down to 2000 FT. Putting the gear down would have helped but I didn't even think of it. At 2000 still above the GS the jet leveled. I reached over and rolled the MCP down to 00000 and in the same movement rolled it back up to something say that 'zero is allowed'. I told the FO to set something so I could V-Speed down. Got the flaps to 20 and lowered the gear late; 1400-1300 FT; landing checklist. BUT the speed brake was still out. From here we became totally unstabilized. Relief pilot (IRO) right aft seat called-out 'go around.....go around.' He said it twice because I didn't hit the TOGA switch and only pushed up the throttles so he couldn't see things happening AND NEITHER COULD I. I think I hit the autothrottles button; I did not hit TOGA so I had very conflicting info in front of me. Somebody yelled 'speed brake' and I pushed the speed brake lever down. That helped a lot! At some point I finally got it climbing with lots of coaching just via raw data. There was late gear retraction; and flap retraction.
