The problem at first was an intermittent AoA signal. That meant no airspeed and altitude for the captain sometimes because AoA is included in the calculation.
After the change of the AoA sensor in Denpasar the signal was not intermittent but offset by 20 degrees on the previous and the accident flight.

So it could still very well be either that the sensor itself was faulty and not properly checked at the factory or the installation was done "creatively".
