Based on 8.10.151.0 code, AP needs to run 15.3(3)JK5.
Download this file "ap3g3-k9w8-tar.153-3.JK5.tar" from Cisco and put it in TFTP server.
On the AP CLI issue the command "debug capwap console cli", then run the following command.
archive download-sw tftp://<tftp server IP>/ap3g3-k9w8-tar.153-3.JK5.tar
