Cisco 3925 router loadprog error not an executalbe ELF file

[paul dungey]

Good morning,

I have a cisco 3925 router that has come in from a customer with no flash cards installed,

I copied an Image from my pc to a Verbatim 256 MB flash card and installed c3900e-universalk9-mz.SPA.151-4.M4 

upon booting the router in rommon mode I issued the command boot flash:c3900e-universalk9-mz.SPA.151-4.M4

rommom tried to boot from the flash card but I keep getting the error "loadprog error not an executable ELF file"

can I please get some help as to why this happening.

much appreciated,

Paul

Hello!

I recommend you to download and prove with another IOS, this can be corrupt. The extesion of your file is .bin?

Also keep in mind that 3925 (using c3900-... IOS images) is not the same as 3925E (using c3900e-... images)...
