i have researched this and havent found any luck yet. iPhone 5s ios 8.1.2 When i try to restore normally , it gets stuck on waiting for iPhone When i restore via DFU, i get error 21. When i restore in recovery mode it gets stuck preparing for restore. My hosts file has nothing apple related in it. i reset it a few days ago. When i run diagnostics, it says "No iPhone ipod or ipad found." gs.apple.com brings me to a page that says "This page is just a place holder" it has three links, one to apple, one to apache web server and one to tech probs. For weeks now i have been unable to restore. It works on my brothers computer, but that is really a hassle and i want to get my music from this computer. Any help guys?
