    Hello, so I have strange nokia 3120 network bug, well, I had 2 nokias and assembled one :D When I insert one simcard from operator "1" it can't register on the network and after some time gives me network registration failed, with operator "2" simcard it works well(this operator thery rarely blocks cell phones by IMEI, and I think this operator was seller of the phone, and it usually had been locking phones for that network) I thought it was SP(Service Provider) lock, the checked by code SP lock status it gave me error, used DCT4 unlock code calculator, tested 3 codes - on all the same, code error, when I first turned on the phone with operator "1" simcard it showed me message "Check network news"(it's translation from my language), before phone came to me it worked on all networks(for some time(well for 3-4 years)).
    And my question: Is the phone blacklisted or the firmware got damaged?
