Als ik dit mag geloven is mijn telefoon een BB5.0 type en is het onmogelijk:
I’d came across this site and this site (GsmSolutionsLtd), both detailed that it’s almost impossible to unlock Nokia cellphones of BB5.
I’ m not sure that Dejan Kaljevic has came out a working BaseBand5 (BB5) unlock tool box. But, according to gsmsolution reply in thread, exceprt as follow:
…. the essence of BB5 is main procssor “RAP3G”. This name is codename used by Nokia to describe very good Texas Instrument integrtaed prcosseor developed for mobile solutions. It’s new technolgy OMAP 1710(up to 220 MhZ).
Most of the vital terminal/phone information such as locks, customisation etc have been encrypted/signed using a private key before downloading to the phone. This happens in the production phase.
If the information is is changed (ie lock status) the phone will recognise this and will not switch on.
The security system of the phone will apply a reset to the phone after 3 minutes if the security certificate is missing. If the certificate becomes corrupted the phone will reset every 30 seconds.
So to summerize:
BaseBand5 is structured in 2 blocks:
-application engine (AE) and cellularphone engine (CE)
-both are operating indepenently from each other (different OSes)
-both are heavily secured against modifications with all kinds of checksums and public/private key encryption (certificates)
-there is no direct way to communicat/interface CE (Unknown OS); only very indirectly through AE
-AE (Symbian) does not allow to load device drivers which are not included in the ROM (Z:\)
-unlock keys are not based on algorithms but on randomly chosen keys stored in some Nokia database where we probably never get access to
-private keys of Nokia are unkown and its also very likely that we never get access to it
-checksums of Nokia’s public keys along with some loader code are probably stored on processor (OMAP1710 has a internal ROM of 48kb, RAP3G could have something similar)
-RAP3G is not for sale, OMAP1710 is only for cooperated customers with high quantity sales (so no way getting virgin, non Nokia branded, processors to replace them) >>>>
the advice stated that:
DO NOT buy unlock software for Nokia bb5 handsets IT WILL NOT WORK
DO NOT buy unlock hardware for Nokia bb5 handsets IT WILL NOT WORK
