Base Band 5

Base Band 5

Base Band 5, often abbreviated as BB5, is a network locking system implemented on newer Nokia mobile phones.

The system is designed to prevent unlocking of handsets which has not been approved by Nokia or the network. Just like the DCT-4 locking system, the unlocking code is unique to each handset. However, unlike DCT-4, the unlock code is much harder to calculate as each code is randomly assigned to the handset and stored on a special chip.

In May 2007, an engineer named Dejan Kaljevic from Serbia (who earned his fame from the free DCT-3 and DCT-4 unlocking solutions), has released a free program which can unlock many of the older Nokia BB5 phones such as the Nokia 6630, Nokia 6680, Nokia 6681 and the Nokia N70. There were reports for other models include the Nokia E60, Nokia E65, Nokia E70, Nokia N71, Nokia N90, Nokia N91, Nokia N93, but was deemed to be fake, since the unlocker only supports older BB5 models. This is easily done by the end-user through the phone's Pop-port connecting a legacy FBus compatible cable such as DKU-5, to a computer running his unlocking software package. Since then, commercial unlocking solutions have been offered by some others along with successful claims on some newer Nokia BB5 phones as well.

In July 2007, Kaljevic released the instructions and schematics to build a hardware solution for unlocking the Nokia N95. However, it is not designed for end-users, since it requires more advanced knowledge in electronics and soldering skills to accomplish.

In August 2008, Kaljevic released a full unlock box for newer BB5 handsets that doesn't require any soldering.
