Please, Can anyone translate this C small function to autoit

MTK IMEI Algorithm:

int calc_imei(char inp_imei[15], char out_imei[12])
{
    char out_mask[12] = {0xAB, 0xA0, 0x6F, 0x2F, 0x1F, 0x1E, 0x9A, 0x45, 0x0, 0x0, 0x0, 0x0};
    int i=0, j=0;

    for (i=0, j=0; i < 15; i++, j++)
    {

        if (inp_imei[i] < '0' || inp_imei[i] > '9')
        {
            return 1;
        }
        out_imei[j] = (inp_imei[i] - '0');

        if (i >= 14)
            break;

        if (inp_imei[i+1] < '0' || inp_imei[i+1] > '9')
        {
             return 1;
        }
        out_imei[j] += ((inp_imei[i+1] - '0') << 4);

        out_imei[j] = out_imei[j] ^ out_mask[j];
        i++;
    }

    out_imei[j] = out_imei[j] ^ out_mask[j];

    out_imei[8] = 0x57; //Может быть и 0x0, ни на что не влияет
    out_imei[9] = 0xDB; //Может быть и 0x0, ни на что не влияет

    out_imei[10] = out_imei[11] = 0;

    for (i = 0; i < 10; i++)

you can test EXE (Down it from attach)

I don’t think folks are going to want to do your work for you. You would not learn anything.

Autoit has arrays and for loops so this is not really that hard.

Post what you tried so far for better results

adelbak · February 26, 2018

believe me i tried many times but i cant
i have problems with loop

Earthshine · February 26, 2018

Can you post your script so others can also look at it and help?

Even if it does not work

Im coding MTK imei repair tool, and i need this algo to generate imei file and inject it NVRAM file

This algo convert IMEI to HEX

Examble from original tool:

imei.exe 531302165213560 501939357823635

This generate New IMEI in file (MP0B_001_NEW) with this content:

‍‘ON:/ےEWغ}.®1ü|ک,¬@WغEô

IN hex:

9E 91 4F 4E 3A 2F FF 45 57 DB 7D 2E AE 31 FC 7C 98 2C AC 40 57 DB 45 F4

Let's Start with this :'(

Func calc_imei($inp_imei)
    Local $out_mask[12] = [0xAB, 0xA0, 0x6F, 0x2F, 0x1F, 0x1E, 0x9A, 0x45, 0x0, 0x0, 0x0, 0x0]

     For 1 To 15
         ;Your code
     Next

   $out_imei = BitXOR(1,$inp_imei)
   Return $out_imei
EndFunc

anyway he wants us to do it all it seems

Subz · February 26, 2018

Looking at the cache of stackoverflow, they closed that post because he didn't post any code, there wasn't anything nefarious so don't see why it would be blocked on AutoIt forums.

Earthshine · February 26, 2018

Ok. I’ll look at it when I get in office but he better post code here. Not Gimme deh Codez

im about learning. If they’re not coming here to learn and they’re wasting their time and mine

He’s already got most of the difficult stuff done just need to create the arrays and fill them with the shit that he needs

I noticed that he’s not passing two arrays in the main function and he needs two of them

Hello adelbak,

I need to ask you a question: Are you intending to increment twice the "i" variable in the for loop ?

the first for statement initialize i to 0 and j to 0 and an the end of the for loop, I can see is i++, which means, you are incrementing "i" by 1 and also, the for loop when it reaches the close brace "}" will also check for the condition if "i" still less than 15 , if that ok, also increment "i" again. So you are incrementing "i" twice . Also, I can see that you are incrementing "j" at the same time. My question is : Are you intentionally incrementing "i" twice ? if yes, then last "i++" should be removed and then the for loop at the beginning should be like this if I understood your code correctly:

    int i=0, j=0;
    //for (i=0, j=0; i < 15; i++, j++)
    for (; i < 15;)
    {

        if (inp_imei[i] < '0' || inp_imei[i] > '9')
        {
            return 1;
        }
        out_imei[j] = (inp_imei[i] - '0');

        if (i >= 14)
            break;

        if (inp_imei[i+1] < '0' || inp_imei[i+1] > '9')
        {
             return 1;
        }
        out_imei[j] += ((inp_imei[i+1] - '0') << 4);

        out_imei[j] = out_imei[j] ^ out_mask[j];
        //i++;
        i+=2;
        j++;
    }

is that what you intended ? to increment "i" twice ? and "j" will be always incremented to 1 ?

why write their code at all? what do they learn?

@Earthshine, I agree with you, I wrote the code so @adelbak can learn how can be done in AutoIT, but for sure next time he will do things by his own. Also, the trick is not actually by writing the function only, it was also by saving the output to a file, because showing a message box by itself and trying to write the string will not solve the issue as 4 bytes of data for every char will be written, but instead we have to have 1 byte for every char. That's why I wrote all the whole script

yes. you can still do the challenge! do it! and then eek it out so they learn. that's what this site tries to do anyway.

Well being that his upload is a virus or at least a false positive and he had the source I doubt he will do much of any learning since it would have been just as easy to recompile it from source as convert to Autoit
