It is a 5S 4000mah. Is there a way to resurrect the flat cell? What is the recommended procedure?

Isolate the cell and slowly charge it. Not sure what charger you have, but A carefully watched nimh charger usually works well. Charge at a low rate, like .3amp until the voltage gets up to 3v or so. Then swap back to a lipo charge until it gets to around 3.8v. Then charge the pack as you normally would and balance it at the same time. Let it sit for a day or so and then check the cell voltages. If the bad cell is loosing voltage you may want to trash or reconfig the pack.
