    i managed to get back to a working system except now i have no wi-fi and IMEI, ICCID and Modem Firmware are all blank. I think this means that i have no baseband installed and i need to reflash the baseband. however i am not sure of my next step.

    how i got from the error 1011 to here was by doing the following:
    running ipsw in the pwnage tool and only choosing "activate phone"
    then restoring the custom ipsw file in itunes.

    there seems to be a new no wifi fix but i'm not sure if it applies to me and also i can't install bootneuter now on my phone as i have no connectivity over ssh etc, only ibooter or something....anyone got any ideas..thanks folks

    It seems you are in the same situation as me. Even though you can install bootneuter on your phone, bootneuter will hang when searching for existing bootloader settings.

    This is because we've corrupted bootloader/baseband and there is no fix for this yet.

    For those who are stuck on "Determining settings"...

    Please go to this wiki page, scroll down to Utilities, and grab the "sping" program. If you could run it on your iPhone (after unloading the CommCenter) and report the result, that would be useful info.

    Can you also run "bbupdater -v" and quote the errors it spits out.

    ok after running bbupdater -v
    it says the following:
    Resetting target...
    pinging baseband...
    baseband unresponsive to pinging
    Done

    This phone was a v1.1.3 OTB 16gb that i unlocked with Ziphone i believe. The Ziphone version that didn't automatically downgrade bootloader to 3.6. It was fine at first and then my friend reported that it just one day said repair needed. There was no ICCID, IMEI, WiFI address or BT.

    He ran iplus hoping to fix it. But he didn't know it was for v1.1.4 only. So iplus hanged in the middle of the process. We unplugged the phone and i've been trying all sorts of different things to re-flash bootloader and baseband to no avail.

    restoring in DFU to v1.1.1 v1.1.2, v1.1.3, v1.1.4 all give error 1011.

    If sping reports "unexpected result 0xc1" that's a bad sign

    It basically means that although the low-level bootrom noticed you knocking and accepted the serial payload, it refused to run it because it thinks the bootloader has started. But if the bootloader was still active you'd see more characters after the 0xc1, so that means the bootloader has passed control to the baseband and the baseband has spun out of control.

    The boot sequence is bootrom->bootloader<->baseband. The bootrom sanity checks the bootloader before running it, the bootloader sanity checks the baseband before running it. The sanity check is pretty weak though. If the bootloader passes CPU control to the baseband and the baseband is corrupted and throws an invalid instruction or data alignment exception (for example) early in the boot process, the exception vectors are not set up yet and you'll end up in tight loop using dummy handlers.

    In other words, your S-Gold is doing bootrom->bootloader->baseband->tight loop. The tight loop is preventing the bootloader from servicing interactive bootloader requests done by bbupdater, bootneuter, and the rest.

    In theory, if your baseband is empty at the right locations above a0040000, you may still be able to do the A17 hardware hack, which will trick the bootrom into thinking the bootloader is empty and so it would execute your serial payloads.
