    I have a cyclone box. To fix the downgrade contact service problem you need either a full Nokia RPL or the latest version of the cyclone software.

    When you downgrade a 5800 the superdongle keys in pm308 become corrupted. After that you have the contact service problem.

    With the latest cyclone software you can fix this by repairing the superdongle keys and then rebuilding the simlock.
