Hi. The left over part is the small black ground clip on the upper screw of the battery connector. The picture show you where to put it :) You can see it on step 5 in the "iPhone 4S Battery Replacement"-guide Just slide it underneath the batteryclip For the error 4013: Put the left over part back in right place ;) Check the dock connector. Is it connected to the logic board correct? If all seems fine, you could try to restore thru DFU-mode. Check this guide: http://thebigboss.org/guides-iphone-ipod-ipad/dfu-mode
