  • The iPod 'iPod' could not be restored.An unknown error occured(9).

    I got my iPTouch 16 GB on Oct.13 and on hooking to XP SP2 PC got it on the iTunes ver 7.4.3.1, was able to download music after charging. iTunes showed that a new software ver 1.1.1 for iPTouch was available(of150MB).Got it downloaded to iTunes but when it started to download to iPTouch, it failed and asked to do resotre. All this happened in just few hours of getting it.
    Since then, even after reinstalling the iTunes, my iPTouch is not going beyond showing the icon of a plug and a CD.Every time iTune is able to detect the iPTouch saying that it has detected an iPod in recovery mode, you must restore it. And on doing so that error of 'The iPod 'iPod' could not be restored.An unknown error occured(9).' comes up and it again asks to restore.
    Though every time iTunes is able to detect an iPTouch, my XP does not show it in 'my computer' as any hooked device or drive.
    May I request Apple and other members on this forum to help me out. It is clearly a software problem.
    Many thanks in advance.

    Thanks to all members for sharing in. In my case finally, I got a brand new replacement from Apple through their Authorised Service Provider,A-1 Infotech, Mumbai. Since in India, Apple does not have a widespread presence,the service and support I got was amazing.
    In my case though I never came to know whether the problem was of software or hardware, but the simultaneous step I had taken was to call the toll free number of Apple in India and got my problem registered. Since the iPod Touch was under warranty, I got it replaced without much hassels. I advise the same path for other users and if possible get the additional Apple Care Protection Plan for additional one more year.
    Though I have yet to find out how to avail that Protection Plan in India.
    Best wishes,

  • How do i fix [The iPod "iPod" could not be restored. an unknown error occured -1]

    I've been looking through all the discussions regarding similar problems (with different error codes), but all i know is that I cannot restore, I cannot turn on/off my iPod, and I cannot find a discussion to fix this issue.  Any insight would be greatly appreciated.  (P.S. holding down the power and home buttons does squat)

    The cable wasn't the issue.  It was simply turning off every piece of ad/mal/spy/virus scan app that I had running inorder to allow the restore to occur.     (problem solved)...

  • The IPOD 'Ipod' could not be restored an unknown error occured (6)

    just Got my Ipod touch and when I tried to set it up, I got a message that said, 'Itunes has detected an IPOD in recovery mode, you must restore this IPOD before it can be used with Itunes'
    Then I followed up the instruction on my computer but then another subject came up (as what I wrote on the subject)
    I repeated 3-4 times but I got the same message !
    How to fix it ? thanks

    Well, this problem could be an easy fix. Just enter DFU Mode, and then you should be able to restore with no problems. A video on how to do this, is right [Here|http://fr.youtube.com/watch?v=PbTI2quSqew]. There was a better one, but it has been removed. Be sure to have your timing pretty precise, or else it won't work.
    Hope this helps,
    Darie.

    Instructions to get the phone back working temporary.. till there is a real fix.
    1. turn off the phone
    2. fire up iTunes
    3. press and hold the home button, plug in the cable, hold till you get to see the recovery mode
    4. iTunes will the allow to choose restore the phone back to 5.0.1 ( no other choice)
    5. iTunes will then ask you to choose which previous backup to would like to recover.
    (note: please do not reboot your phone unless necessary, i realize at times after reboot, it goes back to sq1)

    My iPhone 3GS 16gb, is stuck in restore mode, downloaded and tried to do a restore multiple times. Keep getting an error The iPhone "iPhone" could not be restored. Unknown error occured (-1). Cannot get it out of restore mode, keeps rebooting!
    I have tried to hold the "home" and "power" button to reboot
    I have tried powering it off
    I have tried, to unplug the cable, hold the "home" button and then plug it in.
    Can't check the SN or warranty, cause it is stuck in restore mode.
    Is the hard drive gone? Should there be something replaced.

    Error 1 or -1
    This may indicate a hardware issue with your device. Follow Troubleshooting security software issues, and restore your device on a different known-good computer. If the errors persist on another computer, the device may need service.
    Usually this is caused by your antivirus or firewall blocking iTunes access to the Internet. It can also occur if the phone is jailbroken or if the computer you are using was ever used to jailbreak an iDevice.

  • The Iphone could not be restored.An unknown error occurred(1604)

    I'm trying to restore my iphone as my iphone suddenly stopped working.I just see silver colour apple symbol when i switch on then it displays usb to itues symbol. thats all..
    so when i trying to restore the iphone i get the below message.
    The Iphone could not be restored.An unknown error occurred(1604)
    i have tried from diffrent computer but i still get the same error.
    can someone help...please...thanks

    Try the following, which worked for someone else:
    Disconnected all other USB items (ext. hard drives)
    Disabled Symantec Anti Virus
    Reset the iPhone to get the screen with the lead pointing to iTunes (Hold down lock button on top)
    Plug iPhone in when this image of Lead/iTunes showing
    Start iTunes
    iTunes recognised iPhone in Recovery mode, offered to restore
    Clicked Restore, it unpacked then tried to run
    iPhone flashed then went to black screen, eventually iTunes gave the dreaded 1604 error.
    I then unplugged iPhone, but instead of resetting it again (which I've tried about 20 times already), I left it with black screen (although black, screen is definately on as not totally pitch black).
    Shut down iTunes
    Plugged phone back in (Still with black screen)
    Started iTunes, again noticed recovery mode, pressed Recover
    The black screen then popped in to life and had a small recovery icon at the bottom in the middle and the restore worked perfectly!!!

    These errors typically occur when security software interferes with the restore and update process. FollowTroubleshooting security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service.
    Also, check your hosts file to verify that it's not blocking iTunes from communicating with the update server. See iTunes: Advanced iTunes Store troubleshooting—follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > Mac OS X > The hosts file may also be blocking the iTunes Store. If you have software used to perform unauthorized modifications to the iOS device, uninstall this software prior to editing the hosts file to prevent that software from automatically modifying the hosts file again on restart.

  • The iphone could not be restored an unknown error occurred 1013 ATTt iPhone

    AT&T iPhone 4
    Last night when I plugged my phone in to iTunes, it told me I needed to update my phone. So I tried to do it. Then it said I need to restore it. So I pressed the "restore button". After several minutes, I get a pop-up error box stating "the iphone "iPhone" could not be restored an unknown error occurred 1013". I've read other discussions with the same issue, but none of the solutions work.
    Please help.

    Exact same thing happened to me. I took it to a local Apple Store and they told me the port was corroded and so they replaced the phone. I took the phone back home, plugged it into itunes, told it to restore my old contacts, and BOOM same error. Iphone could not be restored an unknown error occurred 1013.
    Seeing as how the nearest Apple Store is a two hour round trip from here, I'm very upset. What is up with this last update?
