I have updated to ios 7 beta 4 before, with my iphone 5, and it went fine that time. But recently I updated to ios 7 beta 5 and found out the battery drain problem, thus I downgraded the phone back to ios 6. Now I would like to update to ios 7 beta 4 again, I tried to update with the same ipsw file i used to update my phone few weeks ago, but this message "This device is not eligible for the requested build" popped up I have searched for many threads and videos concerning the problem, but so far what I got from those did not contribute well to the problem. P.S. I don't have the "gs.apple.com" on my hosts file My connection is fine I have tried to turn off the firewall , but doesnt work for the update. ANYONE PLEASE HELP?? I've backed up some important doc. to iCloud during my ios 7 beta 4 usage >.< and now i cant get back those doc. THANKS!
