After I upgrade my IOS, its throwing now an error "Error : compressed image checksum is incorrect 0x4B3A9956".  I know I can recover from this

crash through tftp by uploading IOS but the problem I'm having now is the router is not accepting break signal either through putty, teraterm, minicom. Everytime I send break signal to get to rommon mode it keeps loading bootstrap.  Any solution on this?

 

Thanks
