Mad mad at auth.seForgot to mention a second method to extract kc from a running phone, using Nokias with netmonitor display 52. Again, only some phones have this specific display in their netmon, 3310 I've seen don't. Sim card phonebook entry no 34 has to contain the hex file number (6F20) and after running display 52 phonebook entry 35 should contain the file content. Better check the usual netmon docs for further instructions. Regards, Mad
