ZTE Blade Algo in PHP (need testing)

[..::SuB::..]

I've ported the well known ZTE algo from Delphi to PHP. I can't test it now because i dont have Blade in my hand (lol sounds weird like arrow in the knee

function zteCalc ($imei)
{
    $imeiMD5 = md5($imei);

    $tmp = str_split($imeiMD5, 2);
    
    for ($i = 0; $i <= 15; $i++)
    {
        $tmp[$i] = '0x'.$tmp[$i];    
    }


    $key = '';
    
    for ($i = 0; $i <= 7; $i++)
    {
        $key[$i] = ((($tmp[$i] + $tmp[$i+8]) & 0xFF)*9)/0xFF;        
        $key[$i] = (int)$key[$i];
    }
    $key = implode("",$key);

     return $key;
}

I want to extend this algo with the new one, still in progress. If somebody has it in any programming language and want to share so they are welcome.

Mates i have decompiled the Phone.apk and found the calCode function myself. Then tried to decompile a B04 rom but found the same function. What are the differences? Rather than i think i decompiled the wrong roms. Pelase If you have a ROM dump from a ZTE Blade which do not accepting the old code upload it to somewhere, i want to analyze it a bit.

Thanks in advance.

private String calCode(String paramString)
    throws NoSuchAlgorithmException
  {
    MessageDigest localMessageDigest = MessageDigest.getInstance("MD5");
    paramString.getBytes();
    paramString.length();
    localMessageDigest.update(paramString.getBytes(), 0, paramString.length());
    byte[] arrayOfByte1 = localMessageDigest.digest();
    for (int i = 0; i < 8; i++)
      arrayOfByte1[i] = (byte)((0xFF & arrayOfByte1[i]) + (0xFF & arrayOfByte1[(i + 8)]));
    byte[] arrayOfByte2 = new byte[8];
    for (int j = 0; j < 8; j++)
      arrayOfByte2[j] = (byte)(48 + 9 * (0xFF & arrayOfByte1[j]) / 255);
    return new String(arrayOfByte2);
  }

Solved B04 version:
Contact me if you need the algo.
