How about to backup image using rommon?

The problem could be related to two things:

1) change the port to Ethernet0/1 and connect the tftp server to that port.
2) maybe the ASA image file is corrupted.

I had the same problem, the way i fixed is by changing the config register to xxxf so the las byte had to be f so that it used the boot config to boot up.

Looks like you have either a corrupted image or you have stored the image in a different location in flash

shaig,

try the following command which tells the asa firewall to boot from the flash image:

ASA(config)#boot system flash:/asa804-23-k8.bin
