I previously wrote EPUB and DeDRM: Why Google Play Store is the best eBookStore for iBooks fans. (Bonus: Fixing Adobe Digital Edition crash.), but my efforts to put the books I own on my personal device were frustrated when it turned out all of my Google Play books were DRM free. So I could easily put the ePUBs in Google Drive, upload to Google Play and drop them into iTunes for use on my iPhone.
Today I purchased a genuine Google Play Adobe Editions DRMd book. I was able to remove the Adobe DRM and open it in iBooks on my iPhone. So it's doable - barely. I fear, however, that my app.net friends who think this is an easy solution to eBook DRM problems are operating on a higher plain than I. DRM removal is not the answer to flat (soon falling?) eBook sales. iTunes music style DRM (signed files) is the answer.
I'm not sure I can quite recreate all the steps, but these tips may help Mountain Lion users. Use them while you read and reread Apprentice Alf's guide.
You need to download the following apps and install the first two.
- Adobe Digital Edition
- The limelinx tools (includes the DeDRM app but, most importantly, the DeDRM_calibre plugin)
Search the world's most comprehensive index of full-text books. Calibre is an eBook manager, organizer, and reader that can help you organize and catalog your collection. Plus, you can adapt the files to fit your device's reader format. You can organize your collection by author, publication date or publisher, among others.
- Download your ePub from Google Apps. This process is very cryptic (I think Google wants us to stop downloading these.) Mouseover your book in Play, look for a strange faint dashed line icon, click it to get the download option. You will download a .ascm file.
- Launch Adobe Digital Edition and register yourself with Adobe. Open your .ascm file in ADE, observe that an ePub file is now saved to Documents/Digital Editions. Note that carefully.
- Launch Calibre and then carefully follow the directions for installing DeDRM_plugin.zip into Calibre. Note that Calibre has changed a bit since the directions were written so some interpretation may be needed.
- The directions say: 'On Macintosh and Windows systems no customization is required for ebooks from Kindle for Mac/PC or Adobe Digital Editions (ADE), provided that calibre is run on the same computer and user account as the installation of Kindle for Mac/PC or ADE to which the books were downloaded. The default key is found and stored in the preferences automatically. ' This did not work for me. I had to follow the configuration steps, which are cryptic. I clicked on DeDRM then clicked the customize button the configuration for 'Adobe Digital Editions eBooks', then click on the green + to get 'default_key'. Ignore 'Import Existing Keyfiles'. Then restart Calibre.

- Now, using Calibre, import the ePub file saved in Documents/Digital Editions.
- You should be able to to Save Only ePub format to disk. The ePUB produced at that point is DRM free (or was in my case).
