Mostly this could be solved by applying heat from the rework station to the PCB. You may not direct the heat at any component but just look for an empty portion or space on the board to direct the heat to. For instance, in 9850, I applied the heat on the empty space under the charging connector and allowed it to stay for about 2-3 minutes @ nearly 650 degrees.
The heat will normally travel around the PCB evenly and all sleeping and dormant ICs will wake back to life hopefully. I have succeeded in fixing BBs through this simple but helpful process.
