    Unhappy [1.1.4] No Service/no Signal/no Iccid/no Imei

    my iphone has" NO SERVICE/NO SIGNAL/NO ICCID/IMEI/MODEM FIRMWARE problem"!

    I think it's baseband has been broken,I have tried every method to erase the baseband ,but it seem that we can't erase / reflash baseband with 4.6BL.

    I also try to downgrade 4.6BL to 3.9BL,but also failed. because it will check
    baseband first when downgrade the bootloader.

    so, it is an endless loop, anyone can help me. I found many people has the
    same problem.

    I had that problem after testing bootneuter, and all my restores kept failing. I fixed it but running pwnage and installing a custom IPSW that did not activate/unlock/fakeblank, it only installed bootneuter and images. Then I restored that image onto my phone. Note that my phone had already been pwned before. I don't know if that matters.

    I tried pwned, it's no help for me.
    I think the key is how to reflash bb with 4.6BL.

    I also have the same problem with a phone someone asked me to fix. I'm trying to get BootNeuter on the phone to try to downgrade to 3.9, but its not an easy task without Wifi and I don't have a Mac so Pwnage is out of the question for now.

    Does anybody have a solution? I've even heard that Ziphone might help with erasing the baseband and letting iTunes fix it? Does this make sense?

    I had same problem here after trying to pwn my iphone to 2.0 beta3. i've managed after 3 hours with baseband eraser from installer (iClarified source), restoring 1.1.4 and activate with Ziphone.

    Since BL 4.6 will only allow you to flash a newer Baseband you could try that *cough* leaked beta of 2.0* cough
    but even if you are successful you could be left with an iTouch (depending on which firmware you flash and if that firmwares baseband has been patched) or a complete brick
    or you could google SoLoR tools, somehow when i was unable to erase my baseband with all other available methods this was the only thing that worked

    Thank you for your help!
    I think iphone don't allow to flash the newer baseband , because it can't check the version of current baseband (I think it must have been crashed) .
    perhaps, it can't be fixed unless someone find one tool can reflash baseband or bootloader without checking current baseband
