[gsmsalers]

Hi.
How to make nokia flash unmodifiable,especially ppm area. How to protect ppm file further modification? Becuase we did many efford to translate and editing for ppm. Is it possible to protect make ppm file from editing edit or make ppm and mcu file unsplitable?Is there have anyway apply some wrong structure for ppm chunks,so ppm editors can't edit, but still can used in phones?
Thanks for attention.
