The search for the Lion Air 737, which crashed last Monday and killed 189 people, was extended after divers lost contact with the aircraft's second black box.
The "ping" from the cockpit voice recorder was on Saturday, but the signal was lost yesterday as the divers struggled with heavy currents and murky waters.
Seekers also seek to collect as many personal items as possible and have so far found 859 items.
At least 105 body bags containing passengers' body parts were handed over to the Disaster Redundancy Identification Unit of the Jakarta National Police Hospital.
Lion JT 610 crashed into the sea of Tanjung Pakis in the Karawang district of West Java Province with 30ms of water.

Australian Road Safety Officers assist the Indonesian authorities in downloading and analyzing the flight data recorder that was recovered last week.
It is assumed that the download process was started yesterday, and it is hoped that it will quickly provide clues as to which systems will not work on the almost new level.
The authorities are being pressured to publish the data as the 737 is one of the most used aircraft in the world.
Although this information is extremely important, the cockpit voice recorder is crucial to understanding the pilot's response to the problems.
Security experts ask why the pilots have not simply turned off the autopilot and are flying the car on standby instruments.
However, the authorities will question the pilots of the previous flight from Bali to Jakarta on the nature of the problems.
During this flight, the aircraft had irregular speed and altitude changes for about 10 seconds before the 737 stabilized.
The pilots had requested a return to Denpasar airport before canceling it when the system returned to normal.
