Does that reveal anything?

Unfortunately not with me at the moment.  (I am in France for a while,
and my cable is in the UK.)

Can I do something to force Jose's phone to ignore whatever's in the
NAND?

Yes, that might be a factor.  The SD card holder in Jose's phone doesn't
close as well as it does in my phone: once his card holder is in the
closed position, it will still move down by about 0.5mm more if I press
it slightly on its left hand side.

However, I've tried holding it down (in that way) at the same time as
pressing the power button to switch on the phone, and that makes no
difference.

Also please recall that Jose's SD card seems to work fine in my phone -
so I think his SD card on its own is fine.

Overall, it looks like the remaining software possibility is the content
of the NAND, so please advise what I can do to investigate that further
(without an RS232 cable, unfortunately).
