..:: For educational purpose ::..
I know how to calculate the SPCK in the ZTE cell following:
SFR 232, SFR 341, SFR 342, ORANGE Vegas, VODAFONE INDIE, X760, X761, X960, GX760, GX761, T-Mobile Vairy Touch.
To calculate the SPCK in this cell, you take digits of IMEI number from 4 digit to 15.
The digits are reversed, put the remaining 12 digits and below the 12 digits of NCK. Then we sum digit by digit, and if it is greater than 10, put the digits on the right and BINGO!
as i show, any examples:

To calculate the NCK all part of: 688950000000 and the respective algorithm...
so nck = a*(a+b+c+d+e+f+g+h+i+j+k+l), b*(a+b+c+d+e+f+g+h+i+j+k+l), n*(a+b+c+d+e+f+g+h+i+j+k+l), ..., l*(a+b+c+d+e+f+g+h+i+j+k+l)

This is based on the whole theory by elcapitel, i have only realized of one little step but most of the work was done by elcapitel, we must thank him for this wonderful research.
Let's begin explaining how it is done, but if you have read this whole thread you should know most of what i am going to explain here.
let's take the following imei (only important 12 digits are used)
000002 243814
our first step will be to sum all digits: 0+0+0+0+0+2+2+4+3+8+1+4=24
then we will calculate a line which is the result of our sum 24 by each digit of imei.
0x24=0
0x24=0
0x24=0
0x24=0
0x24=0
2x24=48
2x24=48
4x24=96
3x24=72
8x24=192
1x24=24
4x24=48
this way we have:
000008 862246
now the second step is based on this chart:
Code:
1 ............... 8 2 ............... 6 3 ............... 4 4 ............... 2 5 ............... 0 6 ............... 8 7 ............... 6 8 ............... 4 9 ............... 2 0 ............... 0
but with a little trick, we have to tak our imei and split it in two halves like this:
000002 243814
and now based on the chart we have two make another line based on the digits in the chart which corresponds to the digits on the imei, and inverse the order. it sounds a little confusing but i know you will understand. so for our imei
000002 243814
we have:
284426 600000
pay attention to halves colors so you can understand it better. you can see, for instance, that for the number 2 you get number 6 and so on.
now third step is to use the following line:
688950 000000
which is the magic line you get when you calculate the nck with all 0 in imei.
if we put all three lines in order we get:
000008 862246
284426 600000
688950 000000
we can easily sum digit by digit, and in this case we get this:
862374 462246
which for our surprise will be the nck for the given imei.
so for imei 000002 243814 we get nck 862374 462246 i have tried we a couple of examples and the result is the same, don't have delphi here with me now but sure someone can code this algo and make more tests to see if everything is correct.
this is another test i did:
000012 243814 --> imei sum: 1+2+2+4+3+8+1+4=25
000050 005050 --> firs line
284426 680000 --> second line
688950 000000 --> third line
862326 685050 --> nck
once again thanks for all interested and specially to elcapitel for his hours dedicated to understand this.
Using our method you will get from imei 352353026840550 the following:000002 243814
and now based on the chart we have two make another line based on the digits in the chart which corresponds to the digits on the imei, and inverse the order. it sounds a little confusing but i know you will understand. so for our imei

once again thanks for all interested and specially to elcapitel for his hours dedicated to understand this.
353026840550 --> sum=41
353026840550 --> first step
000024860404 --> inverse using chart described, second step
688950000000 --> fixed line, third step
--------------
931990600954 --> nck
this was done manually, if we compare the nck with the one from VM_Hacker we can see it is the same, so yes, our method seems to be correct, hope you clear your doubts now, luck
In my opinion zte modems are not supported by imei calculator, need to be connected.
This algorithm is for this phones:
SFR 232, SFR 341, SFR 342, ORANGE Vegas, VODAFONE INDIE, X760, X761, X960, GX760, GX761, T-Mobile Vairy Touch.
and zte - G R230 tested by @powerbook here thanks.
may work at other phones zte...

In step 2 is not needed 2 halves, this is just confusing.
Just take digits from right to left of IMEI_12, make table lookup
and write them from left to right.
Code:
IMEI = 354249030017193 IMEI_12 = 249030017193 <-- <-- IMEI_12 Reversed = 391710030942 === TABLE == INDEX: 0,1,2,3,4,5,6,7,8,9 VALUE: 0,8,6,4,2,0,8,6,4,2 INDEX = Digit of IMEI_12 Reversed Table lookup: 3>4 9>2 ... so on Result of step 2: 428680040226

you take line 1 in the picture case : 353026840550
then you take every digit and do it * 8 mod 10 ( multiply with 8 then take the last digit out ) like 3 * 8 = 24 mod 10 = 4 ... when you have done every digit you will get : 404068420000 reverse that and you will get : 000024860404
then you do something like :
var
calc :string;
begin
for i := 0 to 12 do
calc := inttostr(line1[i] + line2[i] + line3[i] mod 10);
code := code + strtoint(calc);
end;

To calculate the SPCK in this cell, you take digits of IMEI number from 4 digit to 15.
The digits are reversed, put the remaining 12 digits and below the 12 digits of NCK. Then we sum digit by digit, and if it is greater than 10, put the digits on the right and BINGO!
