These errors are typically resolved by performing one or more of the steps listed below:
Perform USB isolation troubleshooting, including trying a different USB port directly on the computer. See the advanced steps below for USB troubleshooting.
Put a USB 2.0 hub between the device and the computer.
Try a different USB 30-pin dock-connector cable.
Eliminate third-party security software conflicts.
There may be third-party software installed that modifies your default packet size in Windows by inserting one or more TcpWindowSize entries into your registry. Your default packet size being set incorrectly can cause this error. Contact the manufacturer of the software that installed the packet-size modification for assistance. Or, follow this article by Microsoft: How to reset Internet Protocol (TCP/IP) to reset the packet size back to the default for Windows.
Connect your computer directly to your Internet source, bypassing any routers, hubs, or switches. You may need to restart your computer and modem to get online.
Try to restore from another known-good computer and network.

  • HT1414 my daughter has iphone 3gs and it required an update , so i connected the iphone to itunes for update and the iphone locked up, I had to reset back to factory settings and now the iphone will not activate , what can i do

    My daughter has an iphone 3gs and it required an update. So i connected the iphone to itunes for the update and the iphone locked up . I had to reset the iphone back to factory settings and now the iphone will not activate , Please advise what i can do to get this working for her ?

    Generally this is a sign that the iPhone had previously been
    hacked/modified/jailbroken and the update relocked it to the
    original wireless carrier. If this is the case, only that wireless
    carrier can unlock your iPhone. You must contact them to see
    if they offer unlocking and if you qualify.
    Where did you acquire this iPhone?
    What wireless carrier did you use before this problem?
    Does the app Cydia appear on your iPhone?
    What does it say when you look at Settings=>General=>About=>Carrier?
    Unauthorized modification of iOS

  • IPhone 3GS unresponsive/bricked after iOS5 Update

         First let me start off by saying that I feel Apple is a SUPERIOR company and 99% of the time have excellent things to say about their products. I will, and in this case have once again, continue to buy their products over any other company. That being said....
         I updated my iPhone 3GS on 12 Oct 11. When the process was almost completed I received the message that iTunes was unable to continue with activation at this time. I have called customer support numerous times (Case ID: 252118395) and have gone to the Apple store where I live. No one can seem to figure out what happened with the update or my iPhone. I tried reinstalling the OS over 50 times now and receive the same message. I went three days without a phone before I was forced to buy the 4S model. I am a career soldier waiting to deploy and going that long without a phone was unacceptable. All my 3GS has on the screen now is the gray screen saying "iPhone" and different languages scroll across. The last 4 times I have contacted Apple reference this I sit on hold for about 20 minutes and then it just goes to a ringing sound with no answer. This is absolutely unacceptable and I know Apple is a better company than to just keep giving me answers of, "I don't know what's wrong; keep trying; Give it more time." The Apple store manager at the Colorado Springs store told me it was because iOS5 wasn't compatible with the 3GS model; though your website clearly says it is as I told her. I was also told by an "Apple Genius" at the same store my "best friend" in my case was to "Google" it to see about unlocking the phone and reinstalling iOS 4 but she, "Couldn't really tell me that." Of a side note the complete lack of professionalism and "hey bro" attitude at this store was in stark contrast to the professional atmosphere and service excellence that the late Mr. Jobs fostered. All I want is for my old iPhone 3GS to be restored so at least we can use it for an iPod Touch. I have exhausted all attempts to contact Apple. A prompt response would be greatly appreciated as I know you are a much better run company than this and you give no real e-mail link to help out with such matters. Has anyone else had this issue???

    HI All,
    My iPhone 3Gs is not detecting any carriers.  I have just upgraded to ios 5.
    I have tried my SIM in another phone and it is working OK.  The phone was unlokced by O2 and I have tried an O2 SIM in it which also does not work.
    When I manually search for carriers then none are found.
    I'm beginning to think this is a hardware fault.
    Any ideas?

      i got my iphone 3gs.. and since i updated it to 5.O from 4.1 ive noticed a recurring shut off when im open any of my application..

    Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup, then as new).  Has any of this been tried?

    Hi there Katherine,
    I have an article here that addresses this error code and can give you a few more troubleshooting suggestions for this issue:
    Resolve specific iTunes update and restore errors
    http://support.apple.com/kb/ts3694
    Check USB connections
    If there’s an issue with the USB port, cable, dock, or hub, or if the device becomes disconnected during restore, try troubleshooting the USB connection, then troubleshooting your security software.
    Common errors: 13, 14, 1600-1629, 1643-1650, 2000-2009, 4000, 4005, 4013, 4014, 4016, “invalid response”, and being prompted to restore again after a restore completes.
    To narrow down the issue, you can also change up your hardware:
    Use another USB cable.
    Plug your cable into a different USB port on your computer.
    Try a different dock connector (or no dock).
    Add (or remove) a USB hub between your device and computer.
    Connect your computer directly to your Internet source, with no routers, hubs, or switches.
    If you see your error after changing your USB connections, continue to the next section to troubleshoot your hardware.
    Thanks for coming to the Apple Support Communities!
    Regards,

  • IPhone 3Gs and Mobile Me not updating Issues

    I have an iPhone 3Gs and a mobile me account, everything was working well and if I entered info in my Calender or contacts either on the iPhone or my G5 Tower at home then they would sync up and merge so that the same dates or addresses were in both places.
    Since updating the iphone to 4.0.1 I have had issues with date and contact merging.
    If I add an entry in the calender it appear in my mobile me web calender when sync'ed, but does not transfer to the iPhone. I have checked that on the G5 the calender date book is the iPhones date book. I have checked that Calenders and Contacts are on the mobile me web. but they are not filtering down to the iPhone.
    If I add a date to the calender on the iPhone they are not hitting the G5 tower.
    This was never a problem prior to the phone software update. I have shut the phone down fully and restarted it incase that was an issue. I have also checked the phones Settings
    Settings> Mail, Contact, Calenders and Fetch is set to Push every 30 Mins
    Push > Set to On
    Advanced schedule> Push (Have also tried Fetch as well)
    and
    Settings>for my .Mac email> Mobile Me >
    Mail> On
    Contacts> On
    Calenders On
    BookMarks> On
    Notes>On
    and
    Settings>Calender
    New Invitations Alers > On
    Sync> All Events
    Time Zone Support> On
    Is anyone able to to suggest how I can cure this issue

    I am having the same issue (actually only noticing on phone Mail, haven't checked calendar yet). And this is an iPhone 3GS without the 4.01 update. Been noticing this for a couple of weeks at least. I'll even hit refresh in Mail and it acts like it's trying, but old emails remain (that I trashed at work) and new ones I saw at work iMac are not shown. They eventually update, but not like they should, especially after I have told the phone to refresh. Not the behavior I've known and loved for years.

  • IPHONE 3G STUCK ON RESTORE AND UPDATE AFTER 4.2 UPDATE FAILED HALFWAY THRU

    I plugged my iPhone 3g in to iTunes and a new update was available for it (update version 4.2). So I downloaded it and started the update, and it got to the very last step and it quit and a pop out came saying "The iPhone "iPhone" could not be restored or updated. An error occurred (37)." And now it the iPhone won't even turn on unless its plugged in and even when it's plugged in it only shows the screen that says to plug into to iTunes, which just keeps repeating "iPhone is in recovery mode, needs to be retored to be used". And I have already done EVERY SINGLE TROUBLE SHOOTING STEPS REPEATEDLY. Nothing seems to work, if there is anyone that can help I would appreciate more than anything, this is my sisters iPhone, I was just borrowing it, now I broke it haha, I could really use someones help.
    I also have an iPod Touch 2g from a year or two back that had the same problem but it was completely black no matter what, holding the home and power button or anything wouldnt work. But it still says its connected but is doing the same thing as the iPhone, it won't restore, it quits right at the end and says the same error message.

    Your antivirus or firewall is blocking the update.
    "Error 20, 21, 34, 37: These errors typically occur when security software interferes with the restore and update process. If you are using a PC, follow this article to resolve this issue."
