ASA corrupted IOS

[DeverickDurham82799]

Hi,

I made mistake with upgrade of ASA 5555. Both ASA are down as a result... I need help to understand get a loadable image to the ASA. I have a console cable to a remote laptop, and I'm wondering if xModem can be performed on a ASA. I have reached, but I have no solid answer to get started. There are no options for Xmodem in rommon, only tftpdnld. Is this the case? Will I have to use tftpdnld for my understanding?

MY first time with an ASA.

Regards,

Hi @DeverickDurham82799

Yes, use TFTP from rommon to load the image to the ASA. Here is an example:
