What I mean by bricking is when the access point image get corrupted the during upgrade. The corruption has typically manifested when image was transferred over CAPWAP over WAN link. When an image is downloaded on the flash of COS AP, an upgrade script (upgrade.sh) is executed which verifies the image and returns two success or error codes. In case of first error code, the upgrade is halted but in case of second error code, AP ignores the error and continues to install the corrupted image resulting in AP getting stuck in boot loop.

Are Access point service packs accumulative? What I am asking is will the fixes from service pack 1 through 6 be also included in service pack 7.
