I don't know if it's a good job but i wase very funy
just take the very good howto on this thread, open
your oO calc and do it step by step.
It will give you the base of how it work and how to do it with other tool.
it's not very hight math level but you need to know what is a modulo

I will now do it with PHP
I kow someone have already post it in php but it's a 100 lines long code
to do something very simple.

sory for Pascal, turboXX, VB, or other microchit plateform language
but I'm linux lover :-)

yes moron its all free now.. did you read first where section you enter Gsm Programming & Reverse Engineering

the topic is how to create unlocker soft not looking for unlocker

Just save it as mypage.php on your server and open it by
http://mysite/mypage.php?imei=xxxxxxxxxxxxxxxx

It's possible to make it shorter for example without the three loops
and the comments.
But more easy to understain as it for php novice


<?
//Code by Comdif-Telecom//

$imei=$_GET['imei'];

//remove 3 first digit
$a=substr($imei, 3);
echo 'Use 12 last IMEI digits: '.$a.'<br/>';

// make digit's sum starting with value 0 and make a loop for 13 time to increment the value
$sum=0;
for ($i=0;$i<12;$i++)
{
$x=substr($a, $i,1);
$sum= ($sum + $x);
}
//display the sum
echo 'Sum digits: '.$sum.'<br/>';

//make a loop to give a VAR value to eatch digit digits must be modulo of IMEI digit X Sum
for ($i=0;$i<12;$i++)
{
$x=(((substr($a, $i,1) * $sum)) % 10);
define("A".$i."", $x);
}

// Display the first magic string
echo 'FIRST - STEP: ';echo A0;echo A1;echo A2;echo A3;echo A4;echo A5;echo A6;echo A7;echo A8;echo A9;echo A10;echo A11;

// Function to replace some digits by other will be used later
function replace ($string) {
$table = array('1'=>'8', '2'=>'6', '3'=>'4', '4'=>'2', '5'=>'0', '6'=>'8', '7'=>'6', '8'=>'4', '9'=>'2', '0'=>'0');
return strtr($string, $table);
}

//make a loop to have all IMEI digits defined as a VAR
for ($i=0;$i<12;$i++)
{ $z=substr($a, $i,1);
define("B".$i."", $z);
}

//To display the second magic string need to use the function replace and order them starting with the last
echo '<br/>Second- STEP: ';

echo replace(B2);echo replace(B1);echo replace(B0);

//This is the magic constant number
echo '<br/>Magic- number: 688950000000';

//OK calculate NCK with sum modulo of the three strings
echo'<div align=center>

And this is education version for peoples who whant to learn some
PHP and HTLM base.



<?
//Code by Comdif-Telecom unlock ZTE PHONE and learn php//

// first lesson php code start always with <? in top of code each instruction line or instruction line writed on multi line finish with ;
// line starting with // are just comment you can remove it for final version you can also use the /* and */ balise for multiline comment as above

/* let's start with echo instruction echo does mean write in the page d'ont forget finaly ouptut page will be simple html code
if you put start ' and end ' after echo it does mean take it as texte so I start with simple html balises like <div align="center">
and as in html balise is take as a balise and not displayed in page, ok let's go */

// first send a html balise just to center

echo'<div align="center">';

/* create a form you have to indicate methode GET or POST get methode create link like http://server/page.php?imei=xxxxxxxxxx and post send request without
display the IMEI var it's more secure depending what you whant to do
you can see I close the ' and make something like '.PHP var.' it does mean I whant this part of echo line to not be taked as texte but real php value
action in form is used to indicate on what page you whant to send request: $_SERVER['PHP_SELF'] is same as HTML #SELF it does mean on same page
if you what to have separate page with the form and script just make something like <form action="script_page.php" method="get"> */

echo'<form action="'.$_SERVER['PHP_SELF'].'" method="get">';

// create here an imput text box and give the var name imei by this way when sending it will have the imei=value of the text box page.php?imei=xxxxxxxxxx

echo'IMEI: <input type="text" name="imei" />';

// just add here the buton to send the form and close the form

echo'<input type="submit" /></form>';

// close the first html instruction

echo'</div>';

// Second step script to make calcul based on sent IMEI just start with a check if imei value is received so use the if instruction
// you can see I use the ! before empty ! is a comparator in php it does mean not equal or different so !empty does mean not empty :-)

if((!empty($_GET['imei']))

//after if you have to englobe all instructions to be executed with starting { and ending }

{

// just receive the imei sending by form and put it in a var named $imei

$imei=$_GET['imei'];

// remove 3 first digit of $imei with the substr function substr($imei, 3) does mean take the var value starting by the digit 3
// digit 3 is in fact the 4th because substr count starting with 0 like that 0,1,2,3

$a=substr($imei, 3);

// so you have now only 12 digits and use echo to display, <br/> does mean go to next line

$x=substr($a, $i,1);

// now just add the digit value to $sum variable

// close the loop with }

}

//display the sum witch is normaly now after the loop digit1 + digit2 +digit3 ... magic :-)

Whats about phone which ask 16digits? Example Rio2 and Panama?
Sometimes there that phones which ask for 16digits unlock code....
