    Ok ... might want to elaborate on that What do you mean under access? Login access and ability to utilize all CPU-s? What kind of configuration are they in etc? 10 BlueGenes (if they are the newer ones) would mean a minimum of 20 000 cores as a single rack is 2000 cores and that's the minimum config of a new BlueGene. Older ones might be smaller, but still

    Question

    Could this also help to fix the IMEI 0049 problem with the really f*cked up seczone? To rebuild it?

    Sorry, was just a question!... Everybody is caring about the unlock of 1.1.2 but not about the hundreds of bricked phones...

    I ran the nckbf.exe but at the end it only says:

    your best bet would be to open your own thread to this question

    Maybe a post that will help you guys:

    Q: Does the current Brute Force application on geohot's website help you unlock your iPhone (1.1.2 OTB or any other)
    A: NO

    any way you execute that code and run it the maximum you can come up with is an answer that the NCK is found and then you can send that to geohot and he can unlock his iPhone

    THIS IS A CODE SAMPLE FOR DEVELOPERS, don't take it for anything else.

    Ok, I ran some profiling on the code, obvious place where to start looking for improvements is the TEA decipher/encipher functions:

    Code:
    Each sample counts as 0.01 seconds.
      %   cumulative   self              self     total           
     time   seconds   seconds    calls  ns/call  ns/call  name    
     51.09      3.76     3.76  8340137   450.83   450.83  tea_decipher
     20.92      5.30     1.54  3553634   433.36   433.36  tea_encipher
     17.66      6.60     1.30                             bf
      8.70      7.24     0.64   670411   954.64   954.64  SHA1ProcessMessageBlock
      0.95      7.31     0.07   734790    95.27   966.26  SHA1Result
      0.68      7.36     0.05   767565    65.14    65.14  SHA1Input
      0.00      7.36     0.00   686366     0.00     0.00  SHA1Reset
      0.00      7.36     0.00        8     0.00     0.00  HexDumpLine
      0.00      7.36     0.00        1     0.00     0.00  genkey
    One can gain about 30-50% by just enabling the gcc compiler optimization option -O3, but I guess to improve 10x or 100x we need to work on the TEA part...

    Default Re-encrypt and re-write ltoken

    Seeing as we know the ltoken plaintext, would it be possible to re-encypt it using a known NCK, such as 123456, and re-write the ltoken to the iPhone?

    I guess this is similar but more elegant than what IPSF does (zero out the token entirely). Of course, this would only work on early bootloader phones.

    Would this work?

    A small update to the profile, I copied here the profile which was for a very short run, now running 8 threads and 8+ minutes (the full 8 digit keyspace) the profile is this:

    With regard to encrypting the ltoken with another NCK I think that's what geohot did to test that his BF code works.
