It sounds like you did not solder some pins completely, or damaged the trace or a near by component when removing the old connector.
You can try another data cable. I switched over to Sony/Ericson or Blackberry data cables. They are the best you can get, as the OEM cable do not last long. I have gone through 2 of them, one failed to connect USB to computer the other did a melt down at the tablet connection. Almost damaged my tablet before noticing. Depending on the damage to a USB data cable, the two pins that control Data and Fast charge will only connect one way but not both... Data is considered slow charge, Fast charge will not allow data connection.
