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!

To fix your iPhone stuck in a recovery mode loop is restore it in DFU mode and a common mistake is that people think dfu mode looks the same as in recovery mode but thee is a difference of the look if it shows up with "connect to iTunes" it is in recovery but if it shows up on iTunes but still looks like it is turned off then it's in DFU mode.
