When trying to FTP image to Cisco FirePOWER module in boot recovery mode I got this error “110 Upgrade aborted“.
Two things to check in this case. First, confirm connectivity to FTP server. Output “Verifying” is misleading as one would assume connectivity was confirmed. You can ping FTP server easily from boot mode.
And second, try different FTP server. In my case, I had no issues with Microsoft FTP server and Quick n’ Easy FTP server.
Once you see Downloading message appear the issue is resolved.
