Following situation. I am using the "iSafeBox" Password Safe on my iPhone 6s where I keep all of my account and password details. After upgrading to ios11 however, I found that the app is not compatible and that the developer will not continue development. To make things worse, I also cannot go back to iOS 10 as it is not signed anymore...
I have an old iPhone 6 running iOS 10.3 and was hoping I could restore that one with the backup of the 6S, but iTunes tells me that the version is too old and cannot be restored with the iOS 11 backup.
When checking the backup of the iPhone 6S running iOS 11, I found that the unsupported app was still there and got transferred over into my itunes library. I am now wondering if there is any way I can extract that specific app + data, and load it onto my iPhone 6 running iOS 10.3, then continue using it there?
I am open to jailbreak and all sorts of shady stuff as long as I get back access to my passwords T_T
