GSM7328S v1 FW update problems after 6.2.0.6.opr, boot code update error

I have now come to the conclusion that it is the boot code update that is causing problems.

When the boot code is updated, what files are changed and what does the system do?
Can I do something to wipe it, refresh it, etc?

If I connect to the switch consol at start up, enter Boot Menu and choose option 6, "Update boot code", only thing that happens is:
