Downgrading LWAPP to Autonomous with WLC
In a previous article I was telling about restoring the LWAPP to autonomous, but it’s also possible if you got access to the WLC.
(Cisco Controller) >config ap tftp-downgrade 10.10.10.15 c1250-k9w7-tar.124-21a.JA1.tar L1252-1
And you won’t see anything at the WLC, but you can see at the AP :
