Owners of Xteink’s ultra-compact e-readers have long enjoyed lightweight, pocket-friendly devices, but they faced one major drawback: finding readable content. Unlike Amazon Kindles or Kobo devices with built-in digital storefronts, Xteink e-readers previously forced users to find and transfer DRM-free e-books on their own. That limitation is finally disappearing thanks to new community-developed software that brings free library e-books straight to these tiny screens.
The breakthrough comes from the developers of CrossPoint Reader, a popular free custom firmware for Xteink's X3, X4, and X4 Pro models. The team has introduced a new plug-in system that enables support for DRM-protected files. A new "Protected Content" plug-in allows the miniature e-readers to process files protected by Adobe Digital Editions (ADE), unlocking access to digital library loans from OverDrive’s Libby app as well as purchased books from stores like Kobo.
Because Xteink devices rely on low-power ESP-32 microprocessors, they cannot run the full Libby app or browse digital libraries directly on the device. Instead, the process uses CrossPoint Reader's built-in web server. When readers borrow an e-book through Libby on a phone or computer, they receive a small license file known as an ACSM file. Transferring this file to the e-reader’s microSD card allows the plug-in to authenticate the purchase or loan and automatically download the full e-book.
For users seeking an even smoother experience, a third-party app called Common Stacks simplifies the entire process. Available for Android, Windows, and macOS, the app handles library browsing and transfers borrowed titles directly to Xteink e-readers with just a few clicks.
Although setting up the custom firmware requires a few manual steps, the addition of DRM support drastically increases the appeal of pocket e-readers. Readers no longer have to choose between ultra-portable hardware and access to thousands of free public library titles.
