Algo for Megafon CP09 - GSM-Forum

mix3584 · 02-19-2012, 13:03

Hi!
I write code calculator. today made several models of huawei, zte, alcatel, bb. I would like to add support for megafon cp09 (an analog of zte s320 but with a different algorithm). Does anyone know its algorithm? Upon completion, I'll post the source code of the program.

new MEMBER but the question is look like old member in hosting.

why you hide your real username?

do you have SFR 131 (Huawei) algo ?

mix3584 · 02-19-2012, 15:51

131 never seen before. Is this an analog of a megaphon? Then i try to look for it. Thanks

mix3584 · 02-20-2012, 06:50

Another calculator.
All algorithms are found in this forum. In the source code is a reference to the relevant to topic. Unfortunately, the Megafon algorithm is not found. I would appreciate it if someone would help.

The program is written in Qt 4.7. If you know C++ it will be easy to understand.

If you do not have libraries of Qt, they can be downloaded here:

Qt 4.7 is for Linux or not?

mix3584 · 02-21-2012, 21:51

Qt for windows and linux. that's why I used it. in the source code binaries for the two systems

still looking for a megafon. Here's a screenshot of the one program

and http://forum.gsmhosting.com/vbb/f272...codes-1180949/

Any ideas?

mix3584 · 06-10-2012, 10:55

Guys, I'm tired by what I can not find an algorithm Megafon

i found multiple dependencies:
1. If the sum of all the imei's digits is even, then the NCK will also be even, and vice versa
Example:
35844 80 20545 82 7 sum of digits 65, nck # 75 77 13 37 #
35706 50 30520 81 3 sum of digits 48, nck # 08 08 46 46 #

2. Knowing the sum and the NCK, we can calculate the difference
Example:
3 5 5 1 1 0 0 3 0 3 2 1 0 7 7 sum 38, nck 08 64 00 86
the difference is 20862208 (formula (sum+diff)%10=nck)
3 5 5 1 1 0 0 3 0 3 2 1 6 9 7 sum 46, nck 80 46 86 24
diff=24802068

3. I assumed that the nck's computation starts from imei[6]. And we can see the difference, what need to add to the sum and imei's digit
Example:
___imei:3 5 5 1 1 0 0 3 0 3 2 1 0 7 7---->code 08 64 00 86, sum 38
_sum+n 1 3 3 9 9 8 8 1 8 1 0 9 8 5 5
________________+2+7-2+3 0+1 0+1
____________________+8
___imei:3 5 5 1 1 0 0 3 0 3 2 1 6 9 7---->code 80 46 86 24, sum 46
_sum+n 9 1 1 7 7 6 6 9 6 9 8 7 2 5 3
________________+2+1-2-3 0-1 0-1
____________________+8+7 +9 +9

An interesting relationship.

Can anyone help in the search algorithm?

We need more imei and there correspanding codes to see well

I have a few:

357065030520813 # 08 08 46 46 #
357065030508867 # 13 51 99 77 #
357065030596789 # 71 73 73 97 #
358448020548318 # 95 75 17 93 #
358448020545827 # 75 77 13 37 #

It is indicative of the two:
3 5 5 1 1 0 0 3 0 3 2 1 0 7 7---->code 08 64 00 86
3 5 5 1 1 0 0 3 0 3 2 1 6 9 7---->code 80 46 86 24

differences in the two digits

try ida with megafon

I tried but could not find an entry point to the flash. Can you tell what address should start to disassemble?

**.:hack3r2k:.** · 06-14-2012, 12:35

FIrst of all that phone isnt MTK based nor ANDROID running and algo isnt free and noone will post for from simple reason teams having it arent retard. Right 922 ?
