  • I have an ipod touch 2 and rebuilt my laptop.  Reinstalled ITUNES and can't find my applications on ITunes after login.  I tried to activate Itunes again but it didn't.  How can I get my applications to display on ITUNEs?

    It sounds like you essentially have a new computer and unless you restored from a backup your iTunes library would be empty.  You can transfer your iTunes purchases from your iPod to the computer by:
    iTunes Store: Transferring purchases from your iPhone, iPad, or iPod to a computer
    SInce you changed syncing computers. after you move the stuff you need to restore the iPod to factory defaults and sync the stuff back to your iPod.  If you had the iPod backup file you could restore from backup.
    If you have non-iTunes pruchases you can copy them to your computer by using one of the third-party programs discussed in this previous discussion:

  • Iphone 5 says "device unknown" when doing the setup

    I try to do the initial setup of my Iphone. When I get to the part of inserting a sim card, the phone "searches" and after a while he says: device unknown, and that I have to contact an apple store...
    Anyone knows what this means?

    this is what they just send me:
    Hi Robert,
    From what we were able to find out, it looks like the micro SIM in your phone is not seated correctly. Please take the phone into your nearest carrier store and have them check the SIM card to make sure it is seated properly. If this still does not work have the carrier replace the SIM card.
    Thanks Again,
    Lorraine
    but I think that's not going to work, because I already tried it with 2 different simcards, and so have you with your simcard from hongkong and the Canadian.

    my iphone says an unknown error occurred (9) when trying to restore in iphone recovery mode

    Hey there ejs11201,
    I see that you are getting an error code when attempting to restore your iPhone. Here is an article that addresses that specific code with some troubleshooting steps and will help you resolve the issue:
    Check your security software
    Related errors: 2, 4, 6, 9, 1611, 9006. Sometimes security software can stop your device from communicating with either the Apple update server or with your device.
    Check your security software and settings to make sure that they aren't blocking a connection to the Apple servers.

  • HT5624 Restore back up of my iPhone-password not recognised. After restore, itunes can not restore because it says the password is incorrect. But I can sign into my apple account with the password.

    Restore back up of my iPhone-password not recognised. After restore, itunes can not restore because it says the password is incorrect. But I can sign into my apple account with the password.  My iPhone is now set to factory settings as a new phone, what can i do to access the back up from my phone before I reset it. 

    That does happen.  It depends on how hard the server is being hit, as well as the connection speed of your system.  If you are on a windows system, you will want to disable any antivirus or firewall software during the download.

  • I resetted my iphone 5s and now it says device unknown. What should i do?

    I havent had service for 2 days now (tmobile), one of the technicians told me to do a reset and so i did but now it says device unknown and directed me to the "Service Answer Center" link. What should I do?

    iOS 7 is a developer Beta only, it can only be installed by registered developers, and issues with the beta can only be discussed in the private Developer forums.
    If you are not a developer, we can't help you as the forum rules prohibit us from discussing the Beta version issues here, and you forfeited support including help from these forums by installing a beta software not intedned for final users at this time.
    There is nothing we can do to help here.  You are on your own.

  • I restored my iPhone 5 to IOS 7.1 on computer and tried to restore from icloud back up. It says "restore completed" but Apple logo keeps popping up every 5 seconds. It restored only contacts and sms. I can access the phone but have to stop if logo pops

    Hello khanhlinh98,
    I would recommend performing the following steps in order to stabilize your iPhone.
    Will not turn on, will not turn on unless connected to power, or unexpected power off
    Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
    Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
    Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
    After at least 30 minutes, if:
    The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see the battery icon in the upper-right corner of the screen. Then unplug the phone from power. If it immediately turns off, seek service.
    The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
    Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
    If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
    If the display turns on, go to step 4.
    If the display remains black, go to next step.
    Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
    If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
    My issue is still not resolved. What do I do next?
    Contact Apple Support.

  • I was in the middle of the latest update and my iPhone now says it needs to restored will I be able to back it up first. I have photos on it I can NOT loses

    I was in the middle of the latest update and my iPhone now says it needs to restored will I be able to back it up first. I have photos on it I can NOT lose

    It should have backed up automatically at the start of the update process. And you should be saving photos from your phone to your computer regularly, just like you would with any digital camera. If you were not doing this you MAY lose the photos, but if your backup at the start of the update was successful you will not. Just DO NOT sync after the update, until you have restore the backup and verified that it is OK.
    What error message did you get during the update? Before you restore do the following:
    Reboot your computer
    Connect to a USB port on the computer directly, not a hub
    disable your antivirus and firewall
    Launch iTunes
    Finally, connect the phone and restore.

  • My iphone 3gs says I need to restore my phone with itunes.  when i connect the phone it says i need to unlock the phone which i cannont due because of the caution saying i need to restore.  does anyone have any idea how to fix this problem

    My iphone 3gs says I need to restore my phone with itunes.  when i connect the phone it says i need to unlock the phone which i cannont due because of the caution on the phone.  How do i fix this?

    Hold down the power button and home button at the same time until the phone powers on, shuts back off, powers on again and continue to hold it until it shows the itunes logo to plug in to itunes. This should allow you to restore without unlocking it.

    Hi there computerfailure,
    You may want to try removing and reinstalling iTunes as an initial troubleshooting step. Take a look at the article below for more information.

  • I restore my US version  iphone 5s  by connecting itunes after restore it shows hello and select country, and activation, but it does not activating why? is it work in china ?

    i restore my US version  iphone 5s  by connecting itunes after restore it shows hello and select country, and activation, but it does not activating why? is it work in china ?

    If the iPhone is locked to a US carrier, you cannot use the SIM card of another carrier on it to either activate it or use the iPhone.
    If you want to use your iPhone with China unicom, you need to get it unlocked by your US carrier.  Contact them to see what their unlocking policy is and if you qualify.

  • Iphone 4 has no service after replacing screen and updating, phone company says sim is fine. any ideas? thanks

    iphone 4 has no service after replacing screen and updating, phone company says sim is fine. any ideas? thanks

    We had this happen with a ipad mini, took it back to person who worked on it, after a week with trying to get it working again, he replaced it. I will agree with the other replies take it back to repair place there must be something inside the phone that if you don't do repair excalty right it messes up all phone functions. Also I would give the repair person a time frame to either get it working or replace it.
