I updated to iOS5 on my iPod, but the restore process failed with:


an error occurred while restoring this iPod (-1).

iTunes could not restor the IPod "Brenda's iPod" because an error occurred.


I can't find any examples of this error on google searches.  I can setup the ipod touch as a new device, but I loose all the game data(and my wife literally has 100 games she plays). 


I've tried disabling firewall/anti-virus.  Restarted computer and ipod.  Any ideas?

iPod touch, iOS 5, windows

    this error is always security software... instead of disabling those firewall and anti-virus you need to try uninstalling them...


    If it isn't a program or software on the computer contact your Internet Service Provider and/or Router Company for help to configure or disable the firewall in the router settings.


    To isolate the issue to this you can also try disconnecting the router and plugging your computer directly in to the modem.

    At least i'm getting new errors now:




    at twice i got:

    itunes could not connect to this iPod because an unkown error occurred (0xE8000065)


    let's see what the third time gets me....


  • brendafromissaquah Level 1 (0 points)

    itunes could not restore the iPod "Brenda's iPod" because the backup was corrupt or not compatible with the iPod that is being restored.


    I'm running a chkdsk next.


    I fear i'll be sleeping on the couch for a bit

    holy cow that's a lot of errors... **** sorry to hear that

    what generation ipod is it and it is an ipod touch?

  • brendafromissaquah Level 1 (0 points)

    iPod Touch 3Gen

    The chkdsk didn't fix any problems.  My only assumption can be AVG blew away some part of the backup.  But i'm at a loss for repairing the situation.

    what error messages are you still receiving? as far as losing the contents that can't be prevented if you didn't back up the device before doing the ios 5 update. itunes restores the device to factory settings anyways when doing the update

  • brendafromissaquah Level 1 (0 points)

    I did backup the touch prior to the upgrade.  I also transfered all the purchases.  Currently I'm getting error (-20) followed by the backup is corrupt.


    As far as i can tell (-20) isn't a listed error code

    Yea this absolutely confirms it's security software...


  • imanog Level 2 (395 points)

    there is something blocking the connection between the computer and the servers that it is trying to connect to.


    If you have a solid internet connection and can browse to websites fine it's either an anti-virus program or a firewall on the computer OR a firewall in the router's settings that you use to connect to the internet.


    Reconfigure any security software to allow Apple's servers to pass.


    Useful information for configuring your security software:

    IMPORTANT: iTunes must be allowed to contact Apple using the following ports and servers:

        ▪    port 80

        ▪    port 443



    iTunes uses well known ports and these ports may need to be opened for iTunes: 80, 443, 3689, 5297, 5298, 5353, 8000-8999, and 42000-42999.


    iTunes also contacts VeriSign servers during an iPhone restore and activation:




    Temporarily disable or uninstall your security software

    If the current available version of your security software is incompatible with iTunes, you can disable the security software and test if it is the source of the issue. It might also be necessary to temporarily uninstall security software after making sure you can reinstall it and note any required licenses. A temporary deinstallation might be required because parts of some security software remain active in the background though they appear to be deactivated.

    To reduce any security risks that security software is designed to prevent, consider making sure all files needed to reinstall it are available and disconnect network connections before uninstalling security software. Should this not be possible, such as if a download without active security software is required, that required step should be the only process completed without security software. For assistance in checking your configuration, disabling, or uninstalling your security software, please contact the manufacturer.

    Once disabled or uninstalled, perform only the steps required to verify your issue has been resolved. Complete whatever update, restore, syncing, back up, activation, or other task you were troubleshooting. Once that task is complete, install and configure compatible security software to ensure your PC is protected.

    AVG has been uninstalled since the first reply.  Also Windows firewall has been disabled.  I've now run a dedicated new network cable from the cable modem directly to the computer.  (FYI:  a different computer on the same network i had no problem updating my iphone4 --> iOs5.)


    Also i don't think (-20) = 20....but apple seems to imply them the same on other error codes.


    Let's see what i get this time.....

  • brendafromissaquah Level 1 (0 points)

    Still get error (-20).  Now i'm putting in a USB NIC....

  • brendafromissaquah Level 1 (0 points)

    Now it's failing without any error code only:


    iTunes could not restore the iPod because the backup was corrupt or not compatible with the iPod that is being restored.


    So am I now officially SOL?
