Both of these messages relate to the image version you are putting on. Older S90 images will not go onto new S90’s. Try downloading a current image and push this. Also if you are using Rapport 4.4.1 make sure you have all the patches on.
Basically the board changed in the S90 to comply with RoHS restrictions in Europe, these new models have the designation as 9S92 and need the newer image,
