    Default [1.1.2 OTB][IBrick] HW Upgrade Stuck reasons/Source code/Experts can help?

    Hi all,

    I took my bricked Iphone and checked the source code of Geohots hw upgrade tools.

    My symptoms are the following:

    ienew stuck at waiting for data

    iunew stuck at Spamming AT, Waiting for response

    Now I checked the source code and found two possible reasons for this:

    Eather a write call is blocking, or the select call is only returning 0 or blocking.

    iunew (iunlocker):

    void getheader()
    {
    fd_set nfp;
    FD_ZERO(&nfp);
    FD_SET(fp, &nfp);
    struct timeval tv;
    tv.tv_sec=0;
    tv.tv_usec=10000;
    hlen=0;
    while(select(fp+1,&nfp,0,0,&tv)>0)
    {
    hlen+=read(fp,data+hlen, 0x1000-hlen);
    printf("Attempting to read[%d]...%x\n",hlen,data[0]);
    }
    }

    And in main:

    printf("Spamming AT, waiting for a response\n");
    do {
    data[0]='A'; data[1]='T';
    if(write(fp,data,2)==-1) {printf("Can't write\n"); return -1; }
    //else printf("W\n");
    getheader();
    }while(hlen==0||data[0]!=0xc0);

    I guess that those calls are pretty close to the hardware and I assume that
    the reason for those calls could be a broken trace (A17 ? ), I'm going to check that and maybe try to fix it then ....

    Maybe somebody has another idea why those calls fail ...

    hi schueppi,

    where are you from?

    i have the same problem here.
    another person told us the same that the reason is a broken trace.
    now i think about how to check the trace. a magnifying glass is not good enough.

    what are you gonna use to check the trace? and if its really broken how you gonna fix it??

    thx
    gstar

    edit:
    question: if you can fix it what unlock do you choose? the HW unlock or the new SW unlock? iam just curious.

    A Magnifying glass should be enough to check the trace.
    In any case, try redoing the trace with a pencil, the graphit in there might be enough to connect it again. If its not you might want to solder them back together.

    - H/W downgraded to BL3.9 then unlocked.
    - Now soft upgrade to 1.1.3, still jailbroken and unlocked.
    - Restored to 1.1.4 and unlocked using repo by iClarified.
    Works like a charm, if you have questions: PM me!

    I can help personally or by remote, webcam is an advantage.

    you mean a "bleistift" is enough? and this can fix it forever?
    i thought about a conductive pen for trace repairing.

    Yes a "bleistift" might be enough to fix it
    Well if you have such a pen then use that one instead but watch out that you do not hit any other traces connecting them!

    @techcity: Put it in dfu mode, restore to 113 using itunes then use ziphone to activate and jailbreak.
    Then install bsd and anysim1.3, set auto-lock to never, put the phone in airplane mode and run anysim1.3

    this is not mine - and i cannot find the thread to quote - but thanks to original poster


    this worked for me:

    make sure the CommCenter plist is unloaded. make sure, while inside folder, you chmod 777 *. if that fails, type ps -A and find the PID's of everything running in the /System/Library/Fr... and then issue kill -9 123 (replace 123 with the PID number of the process). once all those are killed, try bbupdater -f *fls -e *eep command and hopefully it works.

    and by the way - when i was stuck @ "AT spamming" or "can't write data" i DID turn the phone on and off cause the terminal was not responding.

    everything is working - now but do at your own risk
