APN 616-0347 compatible replacement

walshpjs2112, these should be the compatible batteries: 616-0431, 616-0432, 616-0433, 616-0434, and 616-0435. So it could be the battery, but this error can also be caused by security software (antivirus or firewall) on your computer interfering with the update. 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.
