I'm relatively new to the world of routers, and was messing around in my lab today when I renamed(?) the flash file, causing all kinds of mayhem when I restarted the router:

Cisco 2600:

On startup:
System Bootstrap, Version 12.2(8r) [cmong 8r], RELEASE SOFTWARE (fc1)
Copyright (c) 2003 by cisco Systems, Inc.
C2600 platform with 131072 Kbytes of main memory

loadprog: bad file magic number: 0x0
boot: cannot load "flash:"

If anyone out there may have an answer, an idea, or just helpful destructive advice, it'd be appriciated!

Thanks!
 
sounds like you have the wrong flash for your router. Delete it and load a new flash for your device.


It is what it is!!

Hello there, to be able to help can you please answer the following:
1. Is the router booting into rommon mode? If so just do the following in the romon mode:
dev
dir falsh:
b flash:<and the new name you gave the image>
the router should load the renamed image. However, if you do a dir flash: and next to the image name you get this error (or similar) file does not contain a valid magic no it means that the image in flash is corrupted and you will need to do an xmodem from romon mode and upload a fresh image on flash.
2. If the router boots after all you can rename back the image to the original. As a tip the very top part of the show ver will always show the image version regardless of the name you gave that image ( as seen below in the flash area)... Cheers
 
I was getting this message when I replaced the flash, the new flash had no IOS image on it.
ahh the joys of working in RMON getting a new images...
 
Yes, it boots right into ROMMON mode. I've been very frustrated trying to figure out where to get a non-corrupted image file. I'm eager to try the xmodem piece, but can't find a file to replace the bad one with.
 
Hello there,

You did mention your lab. Do you have any other 26xx on your lab or in production, if yes you should be able to make a clean copy and send it to a tftp server and upload it using xmodem command in romon mode....
