How to recover IOS from ROMMON

rommon 1 > IP_ADDRESS=172.30.10.20 (gives IP address to current device)

rommon 2 > IP_SUBNET_MASK=255.255.255.0

rommon 3 > DEFAULT_GATEWAY=172.30.10.1

rommon 4 > TFTP_SERVER=172.30.10.100

rommon 5 > TFTP_FILE=c3640-jk9o3s-mz.123-14.T7.bin

rommon 6 > tftpdnld  (this command will start the download of IOS from TFTP server)
