Tìm hiểu cấu trúc RPL BB5

Chúng ta nghe nói nhiều đến RPL .Nhưng để hiểu rõ cấu trúc của nó
thì....Khi sử dụng MXkey để read( hoặc Open bằng Notepad ) ta sẽ thấy nó
gồm rất nhiều section.Nhưng có mấy cái quan trọng như sau :

1. NPC - Nokia Public Certificate - without this - phone has no imei and the
security watchdog timer will switch the phone off after 3 minutes
(Security Watchdog is Hardware module in the CPU that monitors software
activity and restarts power to all CPU logic).

2. Simlock Data - this data is needed to be able to accept simcard, if damaged
the phone will be in Contact Service. This data is not related to other permanent data.

3. Energy Management Data - this data holds values for the analogue part
of the chipset, needed to have proper charging and other important power
distribution values.

4. RF tunning data - those are value for the Radio part of the phone. Various
parameters that are needed to have correct working receiver and transceiver

5. Super Dongle Key data and signing - this is special area that contains SX4
key exchange data + signing of the Energy Managment Data and the RF Tuning Data
