iOS 7 deleted all my PDFs on iBooks

i am having same problem. I restored from backup and now can't see tany book, pdfs etc. They appear for 2 secs and they are gone. Need help. Thanks

I've had numerous problems with iOS 7 including missing videos and in iBooks. After erasing my iPad and replacing everything I finally figured out that only the PDFs that I generated on my Mac (with the latest OS 10.8.4) via Preview or Adobe Acrobat Pro (v9.5.5) will NOT work. Books purchased via the Store will work. Downloaded PDFs will also work.

Sorry for the delay in replying. The iBooks database is a file named something similar to iBooks_v10252011_2152.sqlite which resides on your iPod. If you plug your iPod into a Linux computer it will let you browse the files, but I don't know what other ways there might be of finding it since normally Apple prefers to show you the actual book files. I believe iExplorer works perfectly for this, but I haven't tried it.

Deleting the database can change the order the books appear in but if you've got them sorted into categories those will still exist. I've often fixed a crashing iBooks by deleting the database.

I'm having the same exact problem is you my PDFs appear for like two seconds and then disappear I restored from a back up and it don't work i'm pulling my hair out

I'm wondering if I can get into my file system and access in there through a computer, Apple obviously has a problem they need to fix this

I spent about 30 minutes on the phone with Apple when it made my PDFs unreadable. There is no way to fix it short of an update to iOS 7. I gave up on having my PDFs in iBooks and just use Adobe’s PDF Reader for now. I will probably switch soon but for now it does the job. (I upload the PDFs into the app via iTunes, then sync) The people at GoodReader have been very helpful but have also been forthcoming in saying that their app still needs work in being fully iOS 7 compatible.

I swear, deleting the database fixes the problem. But then, I have not generated any pdfs via Preview as you described in your first post.

Yes, if you can browse the iBooks or Documents folders from a computer the books are still there. Apple for some reason keeps books in a couple different places (at least for me).

No one seems to have answered the problem posted by Verzig. I have the same problem, my pdf files in ibooks disappeared after the upgrade to ios7. When I carried out a restore operation from my back up, my pdf files in ibooks appears for some seconds and disappears.

1. When you say deleting the database will fix the issue , could u elaborate what u mean by database? Is that a file location?

2. If you use Disk Aid to browse the iPad files, I found in the iBooks section under iBooks_v1025xxxx_xxxx that if u copy that file and add it to FileApp on the iPad and open the iBooks_...... File as a text file you will find that all your PDFs are listed there. BUT! They are only listing the location on the iPad for example,

File://localhost/var/mobile/media/books/purchases/blank%2013.pdf.NfileFile://loc alhost/var/mobile/media/books/purchases/centering4-jawchuck.pdf

So I don't know if I can access these files on the iPad short of jailbreaking? I'll try this weekend!

But my concern is that these locations are not valid in ios7 ? I won't know until I can access them?

What would be better I guess is if you could take your MacBook to an apple store and and have them restore your iPad back to ios6 and from there extract your PDFs then reupgrade to ios7

3. Apple by not letting use downgrade to an earlier iOS version I fell YOU NEED TO FIX THIS!

Hello TheRealDarnorter sorry I missed your post

I'm sure your method works but I use a Mac and Apples OS not Linux. I tried looking for the database in OS 10.8.5 and did not see anything with the suffix you described on the Mac and certainly cannot access the iOS of the iPad.

As I mentioned before, I fully Erased and replace all items on the iPad, and also did a full Restore and it did not work. iBooks refuses to see the PDFs. On the iPad, as Shapiro2000 mentioned, iBooks launches and displays the PDFs for a fraction of a second then quits to the home screen.

Updating to iOS 7 on the iPad has been a DISASTER and a black hole of time wasted. On the iPhone it has been an even bigger disaster. I know someone who updated. Lots of headaches in accessing his apps.

I spent a good 40 minutes with Apple and they cannot fix the issue short of their engineers writing an update to iOS 7. I finally just shifted my PDFs out of iBooks to Adobe Reader app which seems stable.

APPLE!!! PLEASE FIX THIS PROBLEM!!!

SAME issue and agree with Verzig. At least I now know that others are having the same issues and assume Apple are working on it.
