I dont mean to be rude but if you damaged the connector during a repair you have little chance of attaching a new one which needs to be soldered back on and requires some serious micro soldering skill. Take it to a local PCD specialist along with the new connector. The only exception to this is if the top latch has come off, you can fit a new latch by inserting it at the open position and fix it by closing it, now it should be fixed in and can open / close normally.
