thanks for your reply

[balaji.bandi]

here is the steps :

1. power off the device

2. connect console cable. (Configure the terminal to operate at 9600 baud, 8 data bits, no parity, and 1 stop bit (9600 8N1). 

3. Power on the device, as soon as you see console output, use break key  or cntr + c

you see ROMMON1 >

not sure what you want after that your choice.

If @balaji.bandi instruction does not work then format the bootflash: and reboot the router.

[balaji.bandi]

if you want to reset the password, if the password option not disabled.
