Had to do a complete reset on my iPad. Backed up the data from it before with iTunes. Restored the data from the backup after the reset. The PDFs that were in my iBooks app are missing, just like Apps that are no more available in the AppSotre. How to bring them back? If you cannot do it with factory tools, any third party software for this?
What I figured out so far:
-When I open the Backup archive with iBackup Viewer, I can see the missing Apps are listed in the backup. Does it mean they could be brought back from there somehow, or it is just a reference for that App, and the App files themselves are actually missing? I don't have the .ipa files for the Apps in question, I checked the iTunes/Mobile Applications folder, and unfortunately the ones concerned are not there.
-When I finish the restore from the backup and open iBooks, the missing PDFs appear for a moment, then disappear, and then they are not visible any more. Only the ones I purchased through the iBooks app. Does it mean they are actually there, just don't appear for some reason, or it is just their thumbnail that appears for a moment, but after the App recognises they are actually not there, it removes them from the list?
Some additional data: usually I have iCloud backups turned off. I am not sure what setting was on for individual Apps regarding iCloud drive, especially for iBooks, but I thought iTunes backs up every data, so I relied on that only. And actually all things are there, Safari bookmarks and history, etc. etc., only iBooks is missing.
