I downloaded a book from barns and nobel. I have it on my nookstudy software. I found the pdf file but its drm protected. How can I remove it?

Is it a PDF file or a PDB file? Have you purchased this ebook or rented it?

I'm in the same boat. I've thought I was purchasing a book, and now it turns out that I've only rented it and I can't even put it on my mobile reader.

Remove DRM from PDF ebooks (Adobe Digital Editions)

Can you open this PDF file with Adobe Digital Editions?

nope.

you open it in the nookstudy application and i've been poking around in the prefs dir and i only see an sqlite db called clientapi.db with a bunch of obvious information and an email address/password/device_id and some other information that's seemingly encrypted.

Heres a link to the files I have used to crack Nookstudy.

Keep in mind, this skitters the border of illegal as it gets around the rental agreements.

First thing, download the B&N reader program and Nookstudy.

Run the key retrieval .py and then run the other .py and use the key you got from the first script. Run it on your PDF and done.

So I highly recommend to delete the DRM free PDF file after your rental period is over.

DRM removal should only be used to read your PDF file on a Nook or some other eReader. Please do NOT abuse rental licenses!

you first have to open adobe digital editions and authorize with adobe.com, but your barnes and noble account id and your adobe id have to be the same.

then it works the same way as the regular digital editions drm removal from PDF.

Hopefully B&N will allow Nook Study books to be read on Nooks, since this seems to be exactly the reason why most of their customers try to remove DRM from NookStudy PDF files.
