    Please answer as asked


    1. What error (number) thrown out by iTunes ?


    2. If iPhone connectted to computer or a wall charger and the it reboots, does the "NAND error" still shows ?

    For errors 1611 and 1603 see

    If it does not get restored/resolved, it is a hardware failure.

    Check Hosts file of computer. Is it redirecting iTunes away from Apple servers ?


    Delete all lines containing gs.apple.com. Reboot and try restore.

    I know this won't be re-assuring at all but I thought I'd add the extra info..... My 4s died back on the evening of Tuesday, July 9 and was giving the same error.  So today is Friday and I was going to take a drive to the Apple store and have them look at it.  I plugged it in to give it some charge and was having breakfast when I heard the familiar chirp announcing missed calls and messages. Somehow it seemed to rise from the dead and is still acting ok now, maybe three hours later.  I didn't do anything special other than trying to hook it up to Itunes and confirm I could get to the restore optionby holding down the home button, which I did accomplish.  I'll update this link if I learn anythng more.

    I have the exact same problem.

    The only differance is that when I plug in my phone to my computer, it won't pop up on itunes at all and it does not show up in my finder menu. I just want to try resoring it, but I can't even do that.

    So frustrated at the moment.


    Did you end up fixing your phone?

  • bernkraf Level 1 (0 points)

    After my reply of July 12, I did hook up to my computer and do a backup, which I realized had been done when I last plugged my phone in prior to the crash.  The phone has been ok since except for two instances.  In both cases, I had set up to take a photo and then the phone spontaneously rebooted. After the reboots it was ok so I'm trying to hang on with this until I decide to do a replacement.  We're eligible with our carrier now so we're strategizing about when.  Wish I could offer more hope but that's all the info I have right now.
