Windows 7 doesn't recognize iPhone 4

I use Windows 7 64 bit and when I plug in my iPhone 4, it said USB cannot be recognized. It said something about the driver has been manufactored.
It just hapenned a couple days ago, before that I can still use my iPhone with my laptop.
I have tried to restart the Apple mobile device but it doesn't help at all

Tried uninstall re-install.. Nothing works. I just can't get this thing to work on my new PC...

  • Help, windows vista doesn't recognize iphone, can't restore

    Hello everyone, I'm having a problem syncing my iPhone 3g with iTunes to restore it. I received an iphone 3g 16gb from a friend because he didn't want to try to fix it. He told me it broke after he dropped it. Boots up to the apple logo and just stays there, sometimes spinning, sometimes not.
    So I started reading around the net trying to find ways to fix it. I've tried hard resetting (home and wake/sleep same time for 10 secs) and that didn't help. I've tried hooking it up to an itunes with the most recent update and restoring from there. The problem is, my laptop doesn't detect the iphone at all. I have a VAIO with VISTA Business and it is not detecting the phone at all when I plug it in, doesn't show up in device manager or give any indication that the iphone is plugged in other than when I plug it in, the phone boots up to the apple. I've tried plugging in the phone and going into recovery mode from there and I can bring up the screen that shows itunes and the usb cable but nothing shows up in itunes. I've tried getting into DFU mode, but my laptop is still not detecting it.
    I'm running out of ideas so I thought I'd post on the web. Has anybody run into this problem before? I've googled it and checked this forum and others and havent found anything. Is my iphone bricked? Anyone with any experience with similar problems, please let me know!

    A bit of a long shot but you could try and reset the nvram using a stop+N key sequence. Like I said a bit of a long shot which I do not expect to work as it seems you have tried most things.
    I assume that both keyboards work ok on another system and that there are not loose connections between the keyboard, mouse, monitor and the system.
    Does the system boot up, pass diags, etc when the ttya is used. It might be worth while stress testing the system with something like SUNVts.
    You need to also keep in mind this might genuinely be a connector fault with the motherboard, perhaps caused while taking the system apart or moving it.

  • Windows PC doesn't recognize iPod

    I have bought my iPod (20GB, click wheel) one year ago with an extended warranty of 3 years. It was working well all the time. But now my Windows computer doesn't recognize the iPod any more although I haven't changed anything on it.
    The battery can still be charged using the docking station. But as soon as I plug in the iPod on my laptop USB port the iPod freezes. The only message on my laptop screen says that the external hardware can not be recognized.
    The USB port is working properly.
    I have also tried to install the iPod update and to reset the iPod. Nothing is working. I guess I can't restore the iPod since it's not even recognized.
    Thanks, Annemarie

    I thought I was alone with this problem. I recently went traveling last weekend, and began to think the X-Ray machines killed my iPod!
    Whenever I connect my iPod to any computer using the USB connection, Windows will not mount it as a removable drive. The cable is good, because the iPod is being charged but Windows will not recognize it.
    I have tried all the different USB ports, even on several different computers. Including my work, laptop, and my desktop. Windows will not recognize my iPod using the USB connection.
    I'm in the process of restoring my desktop computer after a hard-drive failure (lucky me all my vital data were on a separate drive), so my desktop has a nice clean install of Windows.
    My desktop has a firewire port, so I tried connecting to that port and Ta-Da, Windows recognized and mounted my iPod as a removable drive! Unfortunately my laptop nor my work computers do not have firewire ports.
    Can anyone explain why the USB function suddenly stopped working? Does this mean I need to restore and loose all my music from my iPod? I do not let iTunes manage my music, I do that all myself. I can put my music back onto the device but it will be time consuming. If anyone knows the answer to this USB problem, perhaps you can reply to this thread or contact me.
    Thanks,

  • My computer using Windows 8 doesn't recognize my Canon Rebel. How do I fix this?

    My computer using Windows 8 doesn't recognize my Canon Rebel. How do I fix this?

    Hi MWCRILLY,
    To connect your camera to a Windows Vista or Windows 7 computer or Windows 8 computer, you'll need to change your camera's "Communication" mode.
    To set your camera up for this, please do the following:
    With the camera disconnected from the computer, turn the camera on.  Press the "Menu" button.  Now select the [Wrench, Hammer, 2] tab.  Scroll down to "Communication" and press the "Set" button.
    Select the [Print/PTP] and press "Set".  This process is more completely described (and illustrated too!) on page 121 of your Digital Rebel XT instruction manual.
    Now connect your camera to your computer and turn the camera on.  Your computer should now recognize and have access to your Digital Rebel XT.
    Unfortunately, Canon software cannot communicate with the Rebel XT when operating in this mode.
    You may download your pictures using Windows Photo Gallery.  If you haven't already done so, you may retrieve and install this program from Microsoft's download.live.com.

  • HT201274 attempted to download new ios 6 software. wiped out sim card and computer doesn't recognize iphone now. blinking apple icon is only thing I get

    Need help with iphone 4. tried to download new software and it zorked sim card and phone. Only get a blinking apple icon. Computer doesn't recognize iphone so I can't restore

    Hello henry lfrommiami,
    Thanks for using Apple Support Communities.
    To troubleshoot this issue where your iPhone gives you the message "No SIM Card installed" please follow the steps below.
    Update your iPhone to the latest version of iOS.
    Turn airplane mode on and then off again.
    Restart your iPhone.
    Check for a carrier settings update. Go to Settings > General > About. Install any available update.
    Remove the SIM card and make sure that it's a valid SIM that your carrier provided. Also make sure that it's not damaged, worn, or modified. Then reinsert it.
    A SIM tray that comes with one iPhone model won't necessarily work with a different iPhone model. When you insert the correct SIM tray, the SIM tray should be flush with the device.
    If you have another SIM card, insert it. You can use a SIM card from any phone with the same format as your iPhone SIM card. If your iPhone works with that SIM card, contact the carrier that issued your original SIM card.
    Restore the iPhone.
    If you still see the issue, contact Apple support.
    If you see 'No SIM' alert on iPhone
    Cheers,
    Alex H.

  • Windows & iTunes Does Not Recognize iPhone 4 But It Charges?

    I have an iPhone 4 16 GB Factory Unlocked. Yesterday it was fully working. I don't know why, today, my PC doesn't recognize it, even as an camera. I don't see Apple Mobile Device USB Driver listed in the device manager. Tried several programs concerned with iPhone, but no luck.
    Uninstalled everything related Apple like iTunes, Bonjour, Apple Application Support etc., and used a program called "ByeTunes". Reinstalled iTunes but it does not work. I tried plugging it to my laptop, still doesn't work.
    Also, I'm using Windows 7 x64, and re-installed Apple Mobile Device Support for 64-bit several times. It didn't work.
    However my phone charges, does not beep that plugging sound or show charging indicator but the battery level increases, when I plug it to my computer. But when I try to charge with firewire it works.
    And last, my PC can recognize my phone in DFU mode, fortunately. But I'm afraid of being stucked at restoring process.
    What should I do?
    Thanks.

    I am facing the same issue. Tried everything like, Reinstall Itunes, Tries the sync on 3 diffrent laptops with windoes 7, XP and vista, Connecting in restore mode, DFU, Apple mobile devices restarted..nothing has worked. I am not sure if i do "erase all setting and content" will help  because if the i tunes cant recognise the i phone now, then after erasing everything will it recognise to restore??
    Can any 1 help if i do " erase all setting and content" will help and will itunes recognise the iphone then?

  • Failure to backup while updating 3GS to iOS5 - now iTunes doesn't recognize iPhone!

    Hi, I'm trying to update my 3GS to iOS5. Working on a brand-new Macbook Pro with Lion 10.7.2. Made sure I had the newest iTunes (10.5), synced my phone, transferre purchases to the computer, backed up manually for good measure. Downloaded the iOS5 update with no problem, and started the update process. Seemed to be going slowly but surely through the "backup" step of the update process. I left for five or ten minutes, and came back to a possible disaster:
    - computer had gone to sleep (guess I could have changed preferences, but I assumed that the update-in-progress would keep the computer awake)
    - iPhone screen shows the "plug USB into iTunes" graphic
    - when I woke up the computer, it showed an error message - upgrade failed. I'm pasting the text from the iPhone Updater Log below... it ends with "Restore Error 2009."
    - iPhone no longer shows up as a device in iTunes (or iPhoto). Tried closing and opening iTunes, disconnecting and reconnecting iPhone from USB port, and moving to second USB port. None of these worked. iPhone screen continues to display the "connect USB to iTunes" graphic. I found some relevant lines in the "all messages" log - pasting those below too.)
    Anything I can do, short of bring both computer and phone to the Apple Store? (The phone is past warranty but I have AppleCare for the new computer)
    Does the failure to back up mean that there is no previous backup I can get to? Any way to check if there's a working backup on the computer without it recognizing the iPhone?
    All my apps, contacts, calendar items, music and photos are on my computer, so at least it seems that my data is not all lost. But the phone-to-computer connection doesn't seem to be coming back. Wonder if restarting computer could get it to recognize iPhone, but afraid of doing any more damage.
    Any help appreciated! Thanks,
    Adam

  • Windows Vista doesn't recognize Mac Pro RAM

    I have installed Windows Vista Business on my Mac Pro using Boot Camp, and have found some anomalies that seem strange. It is basically working well (for Windows....).
    1. I installed this on a 500Gb HD on my Mac Pro. This machine is a fully configured box doing video editing, with extensive AV files. It has all four drive bays filled, 3 of them with 1Tb drives, the thrid with a single 500Gb drive. I was a bit surprised to find that Boot Camp won't allow partitioning of its OSX installed boot HD beyond a Mac Partition and the Boot Camp paritition, or a secondary entire HD dedicated to Windows. This is not very practical with these large drives, since even though HD storage is fairly cheap, I don't want to give Microsoft more than maybe 100gb on a drive. All of the other HDs are partitioned for multiple parititions, which I need to preserve. The OSX boot drive has 3 OSX partitions already installed. Any ideas on how to do this better? Yes, I know I can use Parallels or VMWare, and do, but find that native Boot Camp Windows is better.
    2. Windows Vista is running on a dedicated HD in Boot Camp on this machine (to all appearances running fine), but doesn't recognize more than 2Gb of RAM on my machine which is configured with 10Gb of RAM which is recognized appropriately in OSX. What am I missing?
    I would appreciate any help on a partitioning scheme that works to support multiple partitions on these large drives, and a reason that only 2Gb out of 10Gb of RAM is recognized by Windows Vista Business in Boot Camp.
    Thanks!!!

    Thanks for your response.
    I am running in Boot Camp, which runs in native mode without emulation. The advantage is that if you are going to run Windows, which is my goal, it doesn't have the overhead of OSX. Indeed, most Mac machines are among the fastest Windows machines available for equivalent hardware when running Windows in native mode. There are a few more arcane advantages to running natively, particularly in terms of connecting to external devices. There is no background RAM overhead when run natively.
    Thanks....

  • My Windows PC doesn't recognize my iPod as an iPod

    Hi,
    I recently bought an iPod Touch 5 gen and when I plug it to my computer it doesn't recognize it as an iPod but as a non specified device. What's the matter? iTunes doesn't start up when i plug the iPod in, even if I check the box that says it. I must sync the iPod manually, and last.fm software doesn't recognize it as an iPod as well. I tried to plug my iPod to another PC an it works just fine. I cleaned the system registry but it didn't worked. I use Windows 8.1 and the latest version of iTunes.The strange thing is that even when the iPod isn't plugged in, iTunes says that it is plugged in. I really don't know what to do.

    See
    iOS: Device not recognized in iTunes for Windows
    - I would start with
    Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP

    Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
    However, after your remove the Apple software components also remove the iCloud Control Panel via Windows Programs and Features app in the Window Control Panel. Then reinstall all the Apple software components
    - Then do the other actions of:

    I sent hours trying to upgrade my Iphone 3gs to io5 and now Itunes doesn't recognize the phone sim card, I only have a message saying 'There is no sim card in the Iphone you are trying to activate'.   Iphone is no longer under warranty, so I don't know what to do if doesn't work any more.
    Any advice very welcome Thank you!

    Same problem with my 3GS :
    Impossible to activate IOS 5 because itunes say "sorry there is no sim inside"...
    I tried everything and the problem is found on many forum. many people can not activate their iPhone after installing the update.

  • Macbook Pro doesn't recognize iPhone 4Gs

    Macbook Pro doesn't recognize my iPhone 4Gs
    My Macbook Pro 15 (Mac OS X 10.6.8) doesn't recognize my iPhone 4Gs (iOS5.1)
    Suddenly it stopped, last time was April 11 via Wi-Fi.
    Now even with the device plugged it can't be recognized.
    On iPhone Settings, the "iTunes Wi-Fi Sync" tab is grayed.
    Few days ago iPhone started to behave strangely, refusing to power off, sometimes not charging when plugged to USB port, sometimes does.
    Don't know what to do.
    Thanks in advance
    best

    What kind of phone is this? an iphone 4? or an iphone 4S? ( note there is no such phone as an iPhone 4gS)
    What you describe here is in my eyes the beginning signs of accidental damge, such as water damge of some sort.
    This is a great oppurtunity to see if the same issues you are having when connecting to your computer, replicate when conencted to another computer.
    You need to find out if there is a way to test with a new USB cord if possible to rule that out.
    Trying to isolate this to, or away from the iphone.
