Try FonePaw iPhne Data Recovery, 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 iPone; contacts, web bookmarks, all photos, nothing was changed. It just didn't update to iOS 8. After I got it working again I just used wifi and upgraded to iOS 8 over the air with no problems, using it as I type this.
If your iPhone 5 are still stuck in recovery mode, 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 too. Good luck!
