Did you check each cell individually? Is there a single bad cell? If not, it may be a bad connection.

I've tried to revive lipo cells that had a low charge when I bought them - they worked OK for a bit, but didn't do well in the long term. Others may have had more success.

It has been possible to revive 'dead' lipos by charging them using nimh/nicad mode on your charger, just use a low charger current and hit it until the voltage rises above ~3.2v per cell ( of 6.4v total for a 2s pack ).

If there are zero volts though I would agree, check each cells individually, sounds more like a broken or cold joint inside the pack..
