I got a 2611 router, I upgraded the Dram and flash on it.  I did tftpdnld and got the router pulling the ios image from my tftp server, but when it completes copying, i get this error:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
File reception completed.
TFTP copy: operation terminated due to bad checksum comparison.
rommon 14 >

now why is this?  when i reboot the router, it says there's no valid flash as well.

Bad checksum means that most likely the IOS image is corrupted.  You may want to download the IOS image from Cisco's site again and retry the copy to flash.

I wonder if the Flash memory you upgraded with is bad?

Sure sounds like it is bad memory.  Do you have another router laying around that you could test the memory in just to be sure?

Hey JFrederick29, I had to use xmodem transfer.  I was hopping not to do the xmodem because it's a pain to compared to tftpdnld.  :)

Just wanted to let you know.  :)
