Is it truly possible to interrupt a restore at the very beginning and be successful at retrieving photos from an iphone that has been disabled after an ios update?
No Not even apple Hopefully you have an iCloud Backup
Actually there is :) but only if you connect to itunes and it syncs. If so download iFunbox and go into app manger and click photos one you are in photos you can view all of the photos and select them and export them onto your computer.
