I posted it in some other similar threads today and have had three people reply that it worked for them too, and nobody so far saying it hasn't worked. And yes, everything was still on my iPad; contacts, web bookmarks, all photos, nothing was changed. It just didn't update to iOS 7. After I got it working again I just used wifi and upgraded to iOS 7 over the air with no problems, using it as I type this. If you're still stuck, trying this will not endanger anything at all on your device. Worth a try at least, and I'm guessing it'll work for you to recover lost data of
iPhone stuck in recovery mode. Good luck!
