En fouillant un peu sur Google, j'ai trouvé ça : http://discussions.mea.nokia.com/t5/Connectivity/nokia-e71-pc-suite-problems/m-p/741288
Je cite un des posts : The RM-443 belongs to the Nokia 6303c. I guess your E71 is reflashed with a wrong firmware. Your firmware version is 06.40, it should be in this xxx.xx.xxx format. You better bring your device in to a Nokia Care Point.
