If you console into the AP, can the AP ping the Management IP Address of the WLC? If you can, you need to do the following:
1. The AP should have an IOS with the prefix of "RCV", if it has, you need to delete the other IOS with the command delete /f /r flash:c1130-k9w8-mx.124-13d.JA. Once you've successfully done this and other non-RCV IOS, reboot the AP until it loads using the "RCV" image.
2. When you've loaded from the RCV image and you can ping the Management IP Address of the WLC, in enable mode, enter the command lwap ap controller ip address .
Make sure that the CAPWAP UDP ports 5246 and 5247 (similar to the LWAPP UDP ports 12222 and 12223) are enabled and are not blocked by an intermediate device (like a firewall) that could prevent an access point from joining the controller.
