Removing DRM from Textbooks Kno

djwikka · #1 01-19-2012, 11:40 AM

I recently bought a textbook off of Textbooks by Kno for iPad (from iTunes) and want to be able to use the PDF file in my other PDF reader for better annotations...

is this possible? I tried using Calibre and the python scripts but it just says Unexpected EOF

I found out that "Marlin Trust Management Organization" is the one handling their security...

is this possible to circumvent?

I believe "Octopus" is the division that handles their DRM

Any luck with this? I'm also in the same situation.

I also bought a textbook from "Kno," the app sucks though. If someone can figure out how to remove the DRM or make a pdf from the textbook - it'd be awesome

Man, I wish I knew how. Been hunting the internet for a solution but I could not find nothing. Yep the app sucks. It is really bad. I really hope that someone has solutions. The app drives me crazy and being powerless about it does not help. I was able to extract the pdf from the iPad but none of the app on desktop could open it. When I tried to remove the DRM it would say unexpected EOF. Really don't know what to do. Hope someone can help most urgently.
