I haven't heard anything lately, so I looked up the topic and found something which looks interesting.

Is this proof that flight MH370 was downed by a 'blow torch' fire in its cockpit? British lawyers claim missing jet could have suffered same fate as another Boeing 777 three years ago

Investigators pinpointed a problem with the cockpit hose used to provide oxygen for the crew in the event of decompression.
A total of 280 Boeing 777s had been delivered with the faulty wiring, Mr Healy-Pratt said
Following the 2011 blaze US aircraft owners were instructed to replace the system - it is not clear if Malyayisa Airlines had carried out this change,
Mr Healy-Pratt said.
He said the fault can cause a 'blowtorch type fire' that will melt aluminium in a matter of seconds.
