Make sure that your maprom jumper from the B1260 card is removed (open). IIRC from your previous posts, you have a B1260.
If you are trying to create a single-reboot system, make sure that the extracted modules are from BB2 rom update. You only said "rom update" so you could be talking about BB1... I don't know, only speculating. :-)
Finally, here's an example of a BlizKick line designed for a single reboot and all or most of the relevant modules active:
