That's pretty odd. Either the writes are not passed through to the chip,
or another probe sequence irritated it too much. You chipset talks
directly to the Parallel flash chip AFAICS.

Could you perform a cold boot (including removing the power plug), and
run flashrom exactly once after boot with the following command line:
flashrom -V -c W49F002U
That should give us more hints why the ID of your chip doesn't show up
at all.
