    I got libgmp to compile on my Intel Mac. You need to run ./configure with --build=none-apple-darwin9.1.0 (change 9.1.0 to your Darwin version; depends on your OS X version).

    Anyway, I modified it to brute force a 15-digit NCK. On my Core 2 Duo, in about 260,000 hours I'll have my NCK. So I'll see you all in 29 years after my NCK has been cracked.

    Here's what to do:

    FIRST, YOU NEED A 64-BIT SYSTEM. This means, G5, or Core 2 Duo.

    When you compile libgmp, compile with the build x86_64-apple-darwin9.1.0.

    Then, make KEYSPACE a signed long, instead of an int.

    Also remove the if (argv[3] > 8) check in the main() routine.

    Recompile with -arch x86_64.

    you might want to test with ltoken_test first because with 64b I have noticed in a 64b linux box the algo didn't find the test NCK. I'm guessing an endianness issue, but not a good idea to run 29 years with wrong endianness :p

    This means bruteforcing for an NCK of an iphone with bootloader 4.6?


    with 1000 cores with the same speed u have, it would only take 10 days!

    This is a amazing useless use of power for cracking one shitty iphone?

    The news: "Global Warming increased by iPhone hackers."
    hehe

    i think the cheapest and easiest way is to get a turbosim, or i am wrong?:p

    Is it possible to extract the ltoken off of a 4.6 phone? No.

    Anyway, the code is not exactly fool-proof.

    It does find the test NCK on my system. It has two problems however:

    1. The IMEI is not detected (it shows up as some junk). I hardcoded my IMEI into it to fix this.

    2. After so many NCKs it starts going into the negatives. Endianness? I'll try to fix this.

    That's my 64-bit, 15-digit NCK brute forcer. It still has the bugs I talked about above. Myself and another coder are trying to fix them; if anyone can help, please do so!

    The IMEI problem has been fixed.

    New download:

    It still can't correctly verify the NCKs. That needs to be fixed.

    What I've found is, that main() seems to be okay. It's the brute force function that is causing problems. I've verified that everything (dep1_norid, dep2_chipid, A, etc.) are the exact same when run with the 64-bit version and the 32-bit/8-digit version.
