************************************************** **********************************
And here is the code I can't understand:

(1)the 7th line:1F 10 00 40 00 13 01 01 B5 01 2C 82 B9 5B 1B 8B C1 BA 27 1F 94 42 0E 85 48 63 01

I know 'B5' is a security command,and '82 B9 5B 1B 8B C1 BA 27 1F 94 42 0E 85' is MSID ,but I don't know what '48' mean.Does it staid ?

(2)the 9th line:1F 00 10 40 00 19 00 01 B6 2C 5C F8 29 08 43 5E 2E E8 91 AC 7D E3 00 00 00 00 00 00 00 FF BA 23 56

I know '00 00 00 00 00 00 00' is the IMEI I want to change ,and I guess 'B6 2C' is the command change IMEI,but what is the code '5C F8 29 08 43 5E 2E E8 91 AC 7D E3' mean? And when I change the IMEI, for example '00 00 00 00 00 00 01',the code also change to 'C1 88 FE 82 1B 6E E4 24 A3 A3 CE 78'.So ,if I change the IMEI random ,the code also change,but how does it change ?

(3)the 25th line:1F 00 10 40 00 1D 00 01 BA 2C DA 94 E1 65 05 7C 2E D8 EC 47 C0 C7 16 97 03 1E 93 06 2C B9 34 FF DC CF 05 FF 92

What is the meaning of the command 'BA 2C' ,I know the last byte '92' is the ChkSum,but 'FF' isn't the SeqNO,why? And what does the code 'DA 94 E1 65 05 7C 2E D8 EC 47 C0 C7 16 97 03 1E 93 06 2C B9 34 FF DC CF 05 FF' mean? How does it calculate?

Is anyone can help me?
Thanks in advance.
