IOS Upgrade and Console Problem

[batumibatumi]

Hi All,

I have using Cisco 2901 Series Router. 

I wanted to upgrade ISO but unfortunately i can not do it.

My Syntax is:  boot system flash c2900-universalk9-mz.SPA.154-3.M2.bin

after reboot no result. Then i wanted to see what's happening during the reload and i attached wit console and reload the Cisco but during the restart there is no output from the Cisco to the Console. 

in the attached, you can see the image, i was connected via console port, reload my router and no result. During the reload, there was no result.

Could you please advice me what to do to fix it?

Thank you in advance!

Hi Charles,

Thank you for your prompt respond.

I tried this syntax also but no result. The ISO working pretty well more the two years, i only first time need to check why new ISO cannot be loaded in the system but i cannot see the output during the reload, also the i pushed the BREAK button to enter the rommon but cannot access, as i cannot see the output from the console.

Thank you !

Where is the iOS stored?

dir?

may need to try 

boot system flash flash0:/(file)

or flash1:/((file)

possible the baud rate has been changed on the console port?

i would try other baud rates.

can you access the router from the console?

Hi,

boot system flash flash0:/(file)

This was the correct command

Thank you!

Console into the router and boot the router.  I'm suspecting the new IOS is corrupt.
