I just have seen that you did flash other flash chips successfully. Also
the boot block protect mode will not be active after hot-swapping,
because it is reset by power cycling. The behaviour you are observing is
indeed interesting: We can be sure that write cycles reach the chip, as
otherwise, probing would not have worked, but the chip does not respond
to the erase command.

Also we have confirmed working erase on the original Winbond chip. So
currently I am out of ideas why this chip does not erase.
