What does it mean when you power up an ASA and get the following errors repeated endlessly:

Invalid Key: 0020

Invalid Key: 0064

Invalid Key: 004B

Invalid Key: 0020

Invalid Key: 004B

Invalid Key: 0020

Invalid Key: 004B

Hi Denise,

We can try and recover the unit from the rommon using the 
steps in the following link. The 'file' needs to be a valid ASA image, 
eg: asa824-k8.bin

Hi Bro

The ASA software image is either damaged or corrupted. You'll need to reinstall the software image on your ASA FW. Here's a Cisco document for your kind reference;
