Hey there,

Since i had many requests about SBK because i had to stop my webserver, i decided to write a small Windows tool to generate easilly your SBK if you already have your CPUID. (Infos about getting your CPUID -> http://forum.xda-developers.com/showthread.php?t=1624645)


Easy to use :

Extract both exe and dll in the same folder.
Launch SBCalc.exe, type your CPUID, clic "Generate", and it will return your SBK.


Update :

v1.1 : Support 15 or 16 digits for CPUID

For Linux fans, the following piece of code (adapted from Skrilax_CZ's boot menu) seems to work too:
Code:
#include <stdio.h>
#include <stdint.h>
#include <string.h>
#include <ctype.h>
#include <stdlib.h>
#include <arpa/inet.h>

int
main (int argc, char *argv[])
{
  char uid[16], *p;
  uint32_t sbk[4];
  int i, j, mult;

  while (--argc)
  {
    p = argv[argc];
    if (p[0] == '0' && p[1] == 'x')
      p += 2;
    if (strlen (p) != 16)
      continue;
    strncpy (uid, p + 8, 8);
    strncpy (uid + 8, p, 8);
    for (i = 0; i < 16; i++)
      uid[i] = toupper (uid[i]);

    memset (sbk, 0, sizeof (sbk));

    for (i = 0; i < 4; i++)
    {
      sbk[i] = 0;
      mult = 1;
      for (j = 3; j >= 0; j--)
      {
        sbk[i] += uid[4*i+j] * mult;
        mult *= 100;
      }
    }
    for (i = 0; i < 4; i++)
      sbk[i] ^= sbk[3 - i];

    printf ("0x%08X 0x%08X 0x%08X 0x%08X\n",
        htonl (sbk[0]), htonl (sbk[1]), htonl (sbk[2]), htonl (sbk[3]));
  }

  exit (0);
}

Same thing in Perl:

Code:
#! /usr/bin/perl

sub chunk
{
  my ($mult, $res);

  $mult = 1;
  $res = 0;
  for (reverse unpack 'C4', uc shift)
  {
    $res += $_ * $mult;
    $mult *= 100;
  }
  $res;
}


for (@ARGV)
{
  my (@sbk, $i);

  s/^0x//;
  next
    if (! m/^[[:xdigit:]]{16}$/);

  @sbk = map { chunk $_ } unpack 'x8 (A4)4', $_ . $_;
  for ($i = 0; $i < @sbk; $i++)
    { $sbk[$i] ^= $sbk[-$i-1]; }
  @sbk = map { unpack 'N', pack 'L', $_ } @sbk;

  print +(join ' ', map { sprintf '0x%08X', $_ } @sbk), "\n";
}

Thanks so much for the Perl code! You can see it in action at my new SBK Calculator site: http://a500bootloaderflash.tk/sbkcalc/
I hope you don't mind me using it in the true spirit of Open Source! :)

Hello vache,

great tool, but i've got a problem...
if i get my cpuid with "adb devices" it is just 11 digits long...
your tool said that it have to be 15 digits.

and if i use your a500 manager there are 16 digits and characters in my serial number
