Hello, I have upgraded to iOS 8 GM, but I was having some wifi problems and didn't like to lose my jailbreak at all. I tried restoring back to iOS 7.1.2, but every time I try to restore my backup (whose I did with all my files) itunes prompt me an error telling that I can't restore the backup because the lower version of the iOS (7.1.2). So, let me ask you: Is there a way to revert back to iOS 7.1.2 using my backup? All I want is my whatsapp history (I can't restore from iCloud backup on iOS 7.1.2 too), messages history and all my photos! Any help? Thanks anyway!
