I hope Paphitis can correct me if I'm off track here.
Chris Goodfellow is focusing on the nose gear tyre burning on takeoff. It was a night takeoff, so you would think if the tyre got a flat and heated up due to friction and caught fire, others on the ground would have seen something. They did not.
The pilots would have felt the vibration if one or both the nose gear tyres were gone flat as well as indicators showing the tyre(s) were flat, which if it was at a point of no return for the take off, the captain would have told the tower and ask to return back to the airport after dumping some fuel to reduce the weight for landing. He did not.
Anything like a vibration would result in a rejected Take Off before V1 = point of no return. At Kuala Lumpur, V1 equals Vr (rotate) with 239 passengers on board - a light load for a B777. Therefore, they could reject the Take Off at any point up to Vr (rotate). If there was a problem airborne, then the first choice is to dump fuel and land back at Kuala Lumpur. The Runways at KL are 4kms long.
You would not continue with electrical unserviceabilities and no comms.

As far as I know, the landing gear compartments are not pressurized, which means it gets freezing cold in there, hence people who try to stow away in landing gear compartments turn into popsicles upon arrival at temperatures minus 50+°C. So if it's not pressurized, then the landing gear compartment is sealed off to the rest of the aircraft, not unless the tyre fire has burned a hole through and smoke has gone into the cockpit as well as the whole aircraft, which means that the whole aircraft has also lost pressure. Why does he assume smoke ONLY found itself into the cockpit and nowhere else?
To have a fire you need three things, Fuel, Oxygen and Heat. At minus 50°C in a closed compartment, I don't think any fire can stay alight, not to mention it will be very hard for any Oxygen from outside to get into the closed gear compartment, so the fire would die out soon after take off and killed for good once the temperatures drop to freezing within minutes after takeoff.
Lets assume smoke is coming into the cockpit and the captain has decided to land at a different airport without telling anyone on the ground how ever unlikely that may be. You think he would have at least told the rest of the crew and his passengers for them to prepare an emergency landing. Don't you think some people would start using their phones to try and call their love ones? Chris Goodfellow also assumes that the captain or the co-pilot is no way involved in any foul play. How can he be so sure?
I still stand by my feelings that this aircraft has not crashed, but it safely landed somewhere. For what purpose is what I don't know.....yet.
The Electrical Nav Compartment is located underneath the cockpit. There is a small access panel just behind the Pilots. If there was a fire there, one of the pilots can extinguish it. The pilots would turn off most of the Electronics, but not before Sqawking 7700 and making a Distress Radio Call.
Aviate, Navigate and Communicate is true in that order but also a bit of a cliche they would over use in training, but turning off the Transponder and not making any radio calls is crazy. It's like turning off your eyes and ears.
Landing elsewhere also sounds far fetched. Where on earth can you hide a B777 when the whole worlds Satellites are looking for it?
