Hello,
After step 4 (loading the image), when you reboot the router, the router
will come up with "Router>" prompt. At that prompt, you type "enable". Then
you will come to "Router#" prompt. At that prompt, you need to do the
configurations outlined in step 5:
Router(config)#configure terminal
Router(config)#config-register 0x2102
Router(config)#line con 0
Router(config-line)# speed 9600
When you do the last line, you will loose connectivity. Then you need to
close the hyperterminal, and create a new connection and set the speed to
default (9600). Then you can continue with Step 6.

Hope this helps.

Hello,
In the picture, you are trying to enter "configure terminal" command at
"Router(conifg)#" mode. The router is already in the configuration mode, so
you cannot enter the "configure terminal" command again. Also, the title of
your hyperterminal connection (in the picture) says that it is 115200 bps
connection. So, did you already change the speed and you are trying to
access the device using the new speed or you are yet to change?

Hello,
My bad. I did not check the latest images (for some reasons, I did not find
them attached when I checked before). Anyways, seems like you are in ROMMON
mode again. At ROMMON mode, you cannot type any of those commands. Can you
issue "dir flash:" and post the output here?

Hello,
Try this:
boot flash:c870-advsecurityk9-mz.124-15.T4.bin
If that did not work, just try issuing "boot" command.

Hello,
What is the baud rate settings? Can you try 9600 or 115200 and see if one of
those work?

now a different story. after i create another new connection with 9600 bps, and i type command: "Router(config-line)# speed 9600", then it prompt "Router(config-line)# ". which i need to type the steps 6 first command. once i type, it comes with "^". error message is: "invavild input detected at "^" marker. so whats the problem.

Please read an introduction to IOS configuration before making further attempts.
You are missing the necessary basis and understandings to accomplish any task.

Hello,
In step 6, you should have your hyperterminal connection baud rate set to
115200. When the router comes up, you should see
Router>
At that "Router>" prompt you type "enable"
Router>enable
Then you will get "Router#" prompt. Now you type "configure terminal"
Router configure terminal
Now you will see a different prompt "Router(config)#". At this new prompt,
type "line con 0"
Router(config)#line con 0
Now you will get into line configuration mode "Router(config-line)#". Now
you type "speed 9600". After you type that command, your screen becomes
blank. Now close the current hyperterminal connection, create a new one with
baud rate of 9600. Once the connection is open, hit enter. You will again
see "Rourter(config-line)#" prompt. Now you type "exit". You will go back to
"Router(config)#" prompt. At that prompt, you type "config-register 0x2102"
Router(config)#config-register 0x2102
You will get a message and router will come back to "Router(config)#"
prompt. Now you type "exit" again. You will see "Router#" prompt. Now you
type "Wr mem"
Router# wr mem
You will see a message saying that the router is saving the configuration.
Now you are all set.
