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: boot TFTP image Do you wish to change this configuration? y/n [n]: y enable boot to ROMMON prompt? y/n [n]: enable TFTP netboot? y/n [n]: enable Flash boot? y/n [n]: y select specific Flash image index? y/n [n]: y/n [n]: go to ROMMON prompt if netboot fails? y/n [n]: enable passing NVRAM file specs in auto-boot mode? y/n [n]: disable display of BREAK or ESC key prompt during auto-boot? y/n [n]: Current Configuration Register: 0x00000001 Configuration Summary: boot default image from Flash Update Config Regist Booting system, please wait...
