- Verify m5sum (checksum) of the intended image and or download it again , as a sanity check.

Hi,

As explained here: https://community.cisco.com/t5/routing/recover-cgr1120-from-rommon-1-while-bootstrap-is-empty/td-p/3080907 you need to boot from extracted bin file via tftp. it worked for me. Only Eth2/2 interface works when issue "set ip" command under rommon.
