This issue is documented as Field Notice: FN - 72278 - Some C9120 and C9115 APs Might Get Stuck in Bootup with 'Uncorrectable ECC Error' Displayed - Workaround Provided and as the Cisco bug ID CSCwa12652. To recover them, you must console into each AP, and load in a special image via TFTP. These units log 'uncorrectable ECC error' messages to the console during bootup, and are unable to boot successfully. 27, 2021, Cisco manufactured a number of C9115 and C9120 access points with a bad image.
