Hi all
I think maybe you flash your phone with a full flash of 2Mb and changed the IMEI with this, them the phone do not accept SIMs, all locka are closed by this (also if the Nokia Tools says are opened), they are all locks.
Solution is flash with the Dejan Box (not Dejan cable) and restore to the original IMEI with this Box.
I have one on the same situation of you of a friend of mine than do this .
Good Luck
