I am unable to install an IOS on my Firewall (ASA5520) through tftp in ROMMON mode after repeated attempts. When i restarted my Firewall i got the message "Checksum verification on compression loader failed".
I thought that my IOS File was corrupt so i tried to upload another copy of the IOS from ROMMON.
The attached file shows my working and the error which i am getting.
Any help will be appreciated. thanks in advance.
