For the last months I've been developing a midlet using se JCOP part of the secure element in the 6131. It’s been working perfectly until recently I suddenly got the “Problem with the secure element. Contact service provider” when I try to communicate with the reader (Cardman 5321). As I thought it was a failure with the phone I bought a new 6212, and after a while the same thing occurred with that one as well. The only thing I can imagine is that we’ve being doing some work with standard Mifare cards on the same reader (including changing the auth. keys). Could this have provoked the locking of the SE? Is there any way to work around the locking? If not, is it possible to change the SE in the phones?
