    how do I open up Microsoft Security Essentials Issue? I have diabled my Norton firewall and auto protect, but nothing happening. Please help

  • Rubez71573 Level 1 Level 1

    I am using windows XP professional, this disabling option is not available on my MSSE. Are there any alternative fixes?

  • dholleyman Level 1 Level 1

    I have disabled MSSE, I also have symantec endpoint protection which I have also disabled.  Neither of these have worked.  It is still giving me a -5000 error when trying to update my iPhone.

    It seems that if your device is not activated or if you can't receive cellular data you will get this problem. 


    The workaround is to go to Settings, General, Network and turn off Cellular Data.  After the update is complete just make sure to turn it back on.

    I have diabled MSSE.  I have turned off CELLULAR DATA.  I am still getting the same error message :


    “Anerror occurred while backing up this iPhone (-5000)” “Continuing will result inthe loss of all contents on this iPhone” "


    My iPhone is a 3Gs.  iTunes is 10 .5 .1 . 42.


    I'd love to update my iPhone and then my iPad to iOS5.


    Any suggestions ?

    I am still getting the error when trying to update my iphone 4 to the new ios5. This is absolutely ridiculous. I have done everything in this thread. Disable my security on the computer, turned off celllular data and everything. I can't believe Apple hasn't come up with an easier way.

  • GMMV Level 1 Level 1

    I have the same problem.  My itunes and I pad are up to date, but I can't get my iPhone 3Gs to updateKeep getting the same error code: An error occurred while backing up this iPhone (-5000).

  • amyblack Level 1 Level 1

    Did anyone have any more luck with this issue?  I've tried turning off the firewall, turning off the cellular data, and still getting the freaking message...  My husband plugs into the same computer and has no problem so I'm thinking it is with the phone and not the computer???

  • denstop Level 1 Level 1

    I'm getting the same (-5000) error. I've also tried everything , turning off routers, modem's, computers  Iphone even the power to the house. Nothing works. I can't find any error 5000 in any Apple book either. I hope Apple or somebody knows about this and is working on the problem. I have a Iphone 4 IOS 4.3.3.

    Received the - 5000 error.  I'm on a Windows XP machine. 


    Turned off antivirus, turned off firewall, tried again and it upgraded without any trouble.  Hope that helps.

  • databaseguru Level 1 Level 1

    This thread has helped me get past the -5000 error. Thanks, guys.


    (iPhone4, upgrade to iOS 5, on XP Pro SP3)


    A minor update to joc512's suggestion which didn't work for me but put me on the right path:

    1) turn off anti-virus (in this case AVG Free) by setting Serice to disabled & reboot PC

    2) stop Windows Firewall service (or disable it & reboot)


    Seems that just setting the Firewall to 'OFF' wasn't sufficient in my case.

  • bhongkag Level 1 Level 1

    My problem solved. I have Avira. Turn off any antivirus and you're good to go

  • rdkushner Level 1 Level 1

    Thanks, that solved the (-5000) error problem for me.


    I was running Windows XP with Norton Internet Security. I just disabled Norton's "Smart Firewall" and "Anti-Virus Autoprotect" and the backup worked perfectly.
