    On a good note,

    A guy has contacted me who has had the "Your Bootloader Is To Old Problem". He has shipped the iPhone to me for repair so i can have a good look at it.

    The problem is he hasnt a clue how he got it there

    hey pspsully thats good news for shure. When will the phone arrive?

    i tried many tricks on my OTB 112. Nothing worked to corrupt the bootloader
    i killed bbupdater on flashing Bootloader, tried to kill ieraser in process etc.
    But nothing happens...
    I even ran ieraser and bbupdater at the same time.

    pspsully :

    are you part of the dev team?

    A lot of tech talk in here that I don't understand :-)

    Am i right in thinking you are persuing a method to flash phones with 4.6 BL to a 3.9BL so we can use old unlocking methods?

    Cheers

    Cool

    I was just thinkin: would it be possible to write a piece of sowtware that pretends to be a sim card. It would be like a virus taht sends wrong info for the bootloader which then accepts its.

    I am awake and back on Track,

    A theory:

    after many many attempts yesterday , of Dumping the firmware with the new boot, I realized that the software creates the file "dump.bin" but doesn't write anything on it, the phone halts and we go back to nothing, I had change pointers of the Dump class (inside NOR-Dumper) and it absolutely reads nothing,

    I'm trying to see where, the program, halts the iphone and then after a while it restarts the iphone again!!!!

    I'll keep you posted guys!!!

    This sounds like a new Harry Potter title to me:
    Harry Potter and the secret of the new bootloader.
    No seriously, keep up the good work guys! I appreciate all the efforts in finding a solution for cracking this new bl. Wish I had the knowledge to help...

    How we doing on this front guys?

    I dont quite understand all the techlingo you're using. So can someone summarise for me?

    Is it looking possible to flash the 4.6bl down to 3.9?

    so we can all understand:

    the EraseReq structure.

    // Erase
    // This command seems to have a backdoor:
    // if low_addr == 0xA03D0000 then size is hardcoded to 0x20000
    // else if low_addr == 0xA07D0000 then size is hardcoded to 0x22000
    // What is interesting is that because the NOR is 4M long:
    // 0xA07D0000 - 4M == 0xA03D0000
    // so... same address, one fold cycled, and erase an extra 0x2000
    // mmm... factory reset? Who want to risk his phone? (assuming you
    // can go around the secpack)
    // Also from the NOR dump, it looks like this range (0xA03D0000 -> 0xA03F2000) is
    // hidden by the read command (would need to disassemble the low level
    // read command to be sure)

    this is inside the NodDump and it might be the key to bypass the new boot


    the range range (0xA03D0000 -> 0xA03F2000) has change!!!?

    is anyone up and reading this... ??
