So I was still running iOS 6.0.x. Not only did apps start to require later ios versions, but also, apple threatened to release iOS8, which - as far as I heard - is rather iCloud-heavy (which is not a good thing). Thus - and because iOS 7's control center could now at least partially replace the SBSettings - and despite my likely missing some features like the unrestrictor, I decided to unjailbreak my device before I was forced to upgrade to iOS8 if I wished to unjailbreak later. Pretty much the standard way, too: - backup - reset (including forced update to iOS7.1.2) - restore from backup However, I now get a "The App GoodReader was not installed on the iPad due to an unknown error (0xe8000007)." in iTunes. The app icon is there - grayed out, though - and clicking it will do perfectly nothing except change the App's name from "GoodReader" to "Waiting...". I'd appreciate some help resolving this.
