Apple’s greatest media player throws out some of the weirdest errors we have seen. Here’s another error message iTunes spewed out on Windows screen when you are trying to update your iPhone, iPad or iPod Touch to either iOS 5 or iOS 6 firmware. Here’s the complete error message, untouched:
An error occurred while backing up this iPhone (-5000). Would you like to continue to update this iPhone? Continuing will result in the loss of all contents on this iPhone.
If you have plenty of important stuffs on your iOS device, then you will know the last line of the error message means the world to you — losing all your contents for the sake of updating to a new firmware that’s buggy as hell is not a reasonable decision. This error appears on all the Windows OS including XP, Vista, 7 and we guess even on Windows 8. But we have a solution, thanks to a Apple forum member.
Solution: “Had the same error, disabled antivirus software (MS Security Essentials) and everything worked fine.” (link)
Such a simple solution, isn’t it? Note that Windows 8 has Microsoft Security Essentials built-in, and here’s how to disable the program: Launch Microsoft Security Essentials, click on Settings > Real-time protection and uncheck “Turn-on real-time protection.”
Another member confirms that turning off Microsoft’s antivirus fixes the -5000 error. Don’t ask us how, just disable it and update your iPhone, iPad or iPod Touch to the newer version, and re-enable the program once again.
I had the same problem with an iPad 2 updating from a Windows 7 machine. Rebooting everything didn’t fix it. Disabling the virus software, Microsoft Security Essentials, solved the problem. Worked perfectly after that.
