Is the ribbon cable itself damaged beyond use? What about the connectors, is only one messed up, or both of them?

I don't know if these are the exact parts used, I don't have the cable handy to look them up, but this is the kind of stuff you need to order.
The cable itself is kind of expensive if you have to buy a whole roll of it.
