You mention 2811 but this is a 2600.

In any case, format flash and copy image again using tftpdnld.

Note if it is not an XM model with maximum RAM installed, you will never be able to use latest IOS.

hi i have cisco 2611 router not an XM model. i have tried via tftpdnld and xmodem. but the result is same.

Old ios image no c2600-is-mz_122-3.bin

As said above you cannot load recent IOS because too little memory.

2600 non-XM is practically useless.
