Hello @dwtdlt3000,

You need to copy a valid image on C2621 again.

You can now recover the C2621 IOS image using one of the following ROM monitor commands *assuming you have a bin file as C2621 IOS*

--xmodem: Use your computer attached to console port has a terminal emulator that has xmodem capability.

--tftpdnld: use TFTP server directly connected to the Ethernet port.
