Battery is totally knacked,its possible something like a light has been left on and this is draining the power from the battery you used to try to jump it as well. Either new battery or take out old one and charge for 24hrs and try that,if cent locking etc are not working it is deffo battery,not starter...by the way check that the jump leads are not broken...that is also a common reason you cant jump it.
