I have a cisco ASA 5550 firewall. I lost my image.
I tried to boot from tftp using rommon to upload new image but it doesn't work, now i want to get back to boot from flash but i'm stuck with the tftp.
When i change the confreg it restarts immediately, it doesn't wait for sync command that saves the configuration to the nv-ram, so all changes are lost ad it starts again in tftp.
What can cause this this problem, what should i try?
This is how i proceed :
rommon #0> confreg
Current Configuration Register: 0x00000010
Configuration Summary:
