Here's the dilemma: My nephew decided to start a new game on GTA vice city which wiped out my hard worked progress. I have the progress in an old backup from a year ago. However, I would like to not lose the data I have from other apps.
What I have: iPhone5 iOS 9.3.1
What I have tried: iExplorer and iPhoneBackupBrowser
Story of my attempts: I have found the GTA data in iExplorer and have saved to my desktop. However, the app doesn't have iTunes file sharing enabled so I cannot replace the existing files in the "documents" for the app from the backup. I have also tried to downgrade the iPhone to iOS 8.3 but as the ipsw is unsigned, I cannot downgrade.
So: What is the best way to achieve this? I could restore the phone from the old backup and then backup only the GTA app to iCloud, the restore the phone from the recent backup and then sync with the cloud. However, I feel that it will simply wipe out all other apps and only restore the one selected app. Is that correct? What other options do I have? Could I merge the backups somehow? Could I do this via iTunes sync where the data of the correct GTA savegame is synced and replaces the unwanted data?
Could I swap the files in the iTunes backup folder with the relevant files from the historical iTunes backup folder and then restore the modified backup to the phone?
Any pointers in the right direction will help.
