Hi Team,
I have cisco 2800 in my office where the IOS is damage cannot boot at all. How can i upload a new IOS inside the flash drive using card reader or any method to make the router works again?
I've try to delete the file using card reader and upload a new IOS, and reboot the router again & console to it. But its not work.
I used = c2800nm-adventerprisek9-mz.151-4.M10

Hi Closer,
Refer to attached PDF Guide
Make sure your USB format is FAT32 :)
Anyway, since that's a router, use ethernet, don't complicate the recovery process
Though im not saying that it's no possible :P
USB is still an option but just too much steps to be done

You have it right there the way your trying to do it with the card reader , have you verified your md5 incase its corrupt download
did you check you had enough dram and flash to support such a new image as the older routers are usually 256 dram
what are you seeing on the terminal when its trying o boot ? does it go into rommon as you can tftp from there as well ?

Maybe a silly remark, when tftp isn't working make sure your firewall on your laptop or pc is disabled.

I too have tried uploading IOS in 2821 the very same way. But sadly it didnt happened. Better you try XMODEM or TFTPDNLD.

I think I recall the CF used in a 2800 might be dependent on its capacity and how it was formatted. I.e. using any CF in an external card reader might not work.
I also recall, some 2800s could boot directly from a USB stick, but there too, only certain USB sticks worked (like Cisco's). Direct booting from the USB stick also required a boot ROM that supported it (earlier 2800 could be upgraded by flashing their boot ROM).
Does the 2800 boot into ROMMOM? If so, can you "see" files on the CF? If so, you can tell it to try to boot one.
