Cisco UC 520 CUE Reload

Hello,

Trying to reload a Cisco UC 520, CUE, only, the CF card went bad, I replaced it.
There were no backups
Using cli, I did a service-module integrated-Service-Engine 0/0 reload and confirm, then service-module integrated-Service-Engine 0/0 session
config
then boot helper
I get bad magic number, see below
I think I have the wrong PKG file, Cisco web site does not have a download for a download specifically for a 520, which is what I need , I think
Any one know where I can get one ?
