You see this error during the upgrade:
FAILED Unable to Load the LWAPP Recovery Image on to the AP
When you see this error, complete these steps:
Verify that your TFTP server is properly configured.
If you use the Upgrade Tool embedded TFTP server, a common culprit is personal firewall software, which blocks the incoming TFTP.
Check if you are using the correct image for the upgrade.
The upgrade to lightweight mode requires a special image and does not work with the normal upgrade images.
Have another close read of this doc (especially the section deatailing the Upgrade Tool);
