It is, however, more likely that this is another SwissAir Flight 111 incident where faulty electronics or wiring caused a fire.

Possibly. But it seems the crew would have had time to get off a distress signal. There are also witnesses that saw the plane blow up.

Obviously at this point, we’re speculating. But based on what info we do have, it seems like there was no sign of fire in the cockpit, no smoke. The fire was all behind bulkheads and panels and it’s possible the pilots were trying to figure out these error messages on their screen that wouldn’t have seemed to have any real cause. By the time they figured out that there was a problem, their radios could have been out of commission.

People have seen crash planes ‘blow up’ before where that didn’t actually happen. One case in point happened in Texas a while back:

Dozens of people reported it blew up. It didn’t.
