An error occurred when I tried to restore flash IOS using “tftpdnld”command in router series 2600 and 3600. The backup of the routers’ IOS was taken using TFTP server. The routers entered into ROMMON> mode and the IOS could not be restored. The backup of flash IOS of both routers are available in the PCs. However, I am not sure whether the available IOS is corrupted or not. Please go through the attached screen shots of the router boot up and kindly suggest a solution to set it to the default configuration.
