    Guys
    I have an ideal to trick the 1.1.2 OTB to downgrade bootloader from 4.6 to 3.9 .

    last night I try to restore my 1.1.1 phone back to factory mode using Shift+restore button to select 1.1.1 restored file locally ,during the package is extracting I just disconnect the Usb cable with the phone .However the restoring process is still running without knowing that the phone has been disconnected ,I just wonder what if that time I would have a 1.1.2 OTB to plug in and the Itune may recognize the 1.1.2 OTB as an 1.1.1 previously connected to Itune and Itune will be force to restore 1.1.2 OTB back to 1.1.1 with 3.9 bootloader ??? it may works never know if we don't try it ,unfortunately I did not have a 1.1.2 OTB to try it

    Can someone please try to do that and see how it turn out .I really want to know how it will be turned out ,If we could able to manage 1.1.2 OTB back to 1.1.1 with 3.9 bootloader then we have a temporary solution for 1.1.2 OTB running on 1.1.1 FW with 3.9 bootloader and unlock it with Anysim 1.1

    I love to have 1.1.1/3.9BL with Anysim 1.1 ,so far it's very stable and safer than 1.1.2/4.6BL with Anysim ?.?.? (unknown yet)

    whatever you are saying just dosent make any sense, the bootloader does not get written in a firmware restore.

    go check the nortool of george:


    void openbaseband()
    {
    int t1=0;
    int t2=0x126;
    struct termios options;
    fp=open("/dev/tty.baseband",0x20002);
    ioctl(fp,0x2000740D);
    fcntl(fp,4,0);
    tcgetattr(fp,&options);
    ioctl(fp,0x8004540A,&t1);
    cfsetspeed(&options,0x1C200);
    cfmakeraw(&options);
    options.c_cc[16]=0;
    options.c_cc[17]=5;
    options.c_iflag=(options.c_iflag | 0x5) & 0xFFFFF0CD;
    options.c_oflag=options.c_oflag & 0xFFFFFFFE;
    options.c_cflag=(options.c_cflag | 0x3CB00) & 0xFFFFEFFF;
    options.c_lflag=options.c_lflag & 0xFFFFFA77;
    tcsetattr(fp,0,&options);
    ioctl(fp,0x20007479);
    ioctl(fp,0x20007478);
    ioctl(fp,0x8004746D,&t2);
    printf("Opened: /dev/tty.baseband\n");
    }

    and tell,me, am I this noob?.. go talk $hit somewhere else...
    Hey Car_45, in no means was I referring to you as a noob. Why would I?, I don't even know who you are. I was referring to the fact that maybe the person who posted on the other website was someone who accidentally messed up his phone by executing some commands without knowing what they do.

    So no offense here. Btw, if you notice the footer I usually post, I live by truth, compassion and tolerance, so whatever I write, it is never meant to upset anyone. If it did, I apologize

    Best, PmgR

    Regarding this option that bbupdater ask you to upgrade the bootloader to 1.8 or later, even IF we find out what some people did to get into that state I don't think we could do that with the new bootloader, as it won't allow us to trick with the baseband at all... (so, we won't be able to corrupt it or change it in any way)...

    I see some options at the moment:

    1- Geohot is able to find a hardware hack again... (that will ignore all checks/signatures/everything)... and so we could change the baseband/bootloader.. (that would probably happen soon, but none really like to open the iphone, do some soldering... really hard work)

    2- If the bootloader update check is only on bbupdater.. (I really don't believe in that, it would be too good to be true)

    3- We find out another backdoor/bug that allows us to write to the baseband with the new bootloader. (Let's hope the new bootloader dump will be avaible soon, so everyone can look for backdoors/bugs)

    4- We can somehow corrupt the bootloader and be able to get into that "restore to 1.8 or later" state. As I said in the beggining of the message, even if we find out how people did that, we probably won't be able to do the same on bl4.6, as it would probably forbid any thing that is able to corrupt the baseband.. (I really hope I'm wrong on this).

    Any other ideas ?

    The exciting news about this is they still ahve COMPLETE access to the phone and can still SSH into it, i have replied to the thread and PM's both of the people involved to try and find out EXACTLY what they did to get to this situation!! They have obviously corrupted their Bootloader and we need to find out how, and will a reflash of the old bootloader fix their problems!!

    Heres the link to the thread on modmyifone - http://modmyifone.com/forums/showthread.php?t=16314
    PSPSully,
    It seems these guys in the following thread were all having the prior symptom to the "bootloader older than 1.8...." message.

    Hi everyone!

    As far as I understand iTunes does a baseband reflash if the phone is in recovery mode, right?
    What if we disconnect the phone when the firmware gets erased. Difficult to find that moment... but...
    Then we can use the hw hack to flash anything via the bootrom (including a new bootloader) to the phone!

    Default The Checksum

    THE CHECKSUM IS NOT POINTING THE RIGHT OFFSET..

    int Checksum(CmdHeader * packet)
    {
    int sum = 0x00030000;
    sum += packet->opcode;
    sum += packet->param_len;

    int len = packet->param_len;
    unsigned char * buf = ((unsigned char *)packet) + sizeof (CmdHeader);
    int i = 0;

    for (i = 0; i < len; ++i)
    sum += buf[i];
    return sum;
    }

    SOMEONE???

    PLEASE HELP!!
