I understand from some news sources that the authorities in Indonesia have given up searching for the flight data recorder.
I can't believe they'd give up the search for the FDR. There is too much riding on the contents of the recorder that would influence the future sales of the aircraft. Like AF447, they will likely spend lots of money and effort to find it.
This recent news article suggests they have brought army specialists in to help in the search:
