Hi I need help unlocking this Cjb/Bcu I've replaced all main electronics due to immobilised state that no one could help with.
I have dealer Jlr Sdd diagnostics and they will not allow me to start vehicle as there is an ID mismatch basically the donor parts have different Vin to the original vehicle please help this is all I need I've thrown countless pounds and countless hours on this rather large ornament..

You need a new CJB or a full donor ECU set

Security cannot be altered in a used unit

Here lies the issue I already purchased a complete set of electronics how ever they were from a disco 3 all worked fantastic until we went to configure the vehicle also to clear any faults straight away the donor parts went over to the sport how ever because the Bcu ID was different i.e. It was of the donor vehicles part VIN it will not allow us to start car again.
