I assume you mean you had sideloaded epub books to the SD for the stock Nook reader. If so, the stock reader stores its books in /data/nookmedia and may store its sideloaded book information there too (just covers, etc) while the books themselves are still stored on the SD. Deleting the actual books manually may not delete those files.Someone please help as I am going bonkers. I have a nook hd which I rooted in June 2013 following this thread purely so that I could load xbmc. I have not fiddled with the software since. Everything has been working fine for me as I don't use my tablet for anything other than surfing, reading and watching media.
I had all my ebooks loaded onto the sd card. Recently I deleted all of these from the sd via my pc and after some categorising I added them back onto the nooks sd card. Then I found I had duplicate and triplicate ghost files. All I wanted to do was remove these ghost files from my library. Searches online tell me it's virtually impossible without deregistering the device.
I thought I might be able to do something via root but I can't fine the CWM launcher. I downloaded an app to check for 'Su' but that suggests that I've lost root - I still have the backup I made at the time of rooting almost a year ago. The nook is now on firmware 2.2.0 so I don't even know if the old backup would work.
All I want to do is remove the ghost files but right now I'm not sure what I'm actually working with. If I deregister what will i lose and will I have to start again from the start - rooting, trying to add xbmc and downloading all my apps again?
Not sure what my next step is. I could just leave the ghost files but there are over 1,500 showing as books with useless thumbnails which is confusing. Any help would be very much appreciated!
You could try going to settings and applications and clearing the data from the Nook reader app. If that does not work, try going to /data/nookmedia and manually clearing the files there with your root file manager.
