So apparently the 3600 series do not support the tftpdnld to upgrade your ISO when you upgrade your flash. You have to use the Xmodem transfer as described here: Xmodem Console Download Procedure Using ROMmon http://www.cisco.com/en/US/products/hw/routers/ps259/products_tech_note09186a008015bfac.shtml

everything is going great but it is going to take another 3 hours :(

Now when i installed the new flash at bootup it said the "device does not contain a valid magic number" now that is just because the flash is not formatting correctly and downloading the new flash file automatically formats the flash setup? Can someone explain this to me?

make sure to change the raid on your serial connection so you have more bandwidth to push it across. I did a recovery on an 1841 with my rate set to the default cisco 9600bps. That took a while. Other than that, cisco has some neat guides on their website which are pretty straight forward

It has you set it to 115200, which is the max.
 
Oh, here's the best trick to learn. Put the smallest IOS you can find on there and boot into it, then TFTP the IOS you want to use.

I am upgrading the flash so I had to do it this way. I took the 8MB stick our and replaced with a 16MB. The flash I had was already full.

Can you tell me what the "device does not contain a valid magic number" means? is that just when the flash is nor formatted?

"The Flash is empty or the filesystem is corrupted. Copy a valid image on the Flash, and while copying, you will be prompted to erase the old Flash (if one exists). Then reload the router. See Software Installation and Upgrade Procedure for instructions on how to copy a valid image onto the Flash."

Thanks.


Now why on earth does the 3640 not support tftpdnld from ROMmon?
 
Ok after the transfer completed it started doing this stuff. I have never seen this before and it is taking forever? is this normal?

completely normal for this platform, those numbers should be changing at a normal interval.
 
non XM models should take roughly around the same time depending on the code.
 
I am going to strongly advise that you tape in the console connector.

I've only had to do xmodem a couple times - turns out the damn router had some bad flash, so I ended up trying to reflash a couple times (at 8 hours per).

Right. I'm saying to xmodem a very small IOS on there (anything with TFTP... which is basically anything). Then boot that one and use TFTP to copy the one you want. The IOS you're copying is huge and therefore takes a long time.
 
Finally finished and everything is working great!. Thanks for the help everyone. great learning experience tonight.
