Pocket-friendly e-reader manufacturer Xteink is finally overcoming one of its biggest device limitations thanks to the alternative CrossPoint Reader firmware developed by Andrew Liszewski and the open-source community. By introducing third-party plug-in support for models like the X3, X4, and X4 Pro, users can now access DRM-protected ebooks borrowed through OverDrive‘s Libby library app or purchased via platforms like Kobo.
Installing CrossPoint Reader and the Plugin Store
Traditionally, using Xteink hardware meant manually sourcing DRM-free files, lacking the built-in storefront ecosystems found on devices from Kindle or Kobo. However, users can now replace the stock interface by connecting their e-reader via a USB-C cable and flashing the CrossPoint Reader software directly through a browser. Once installed, users download the Plugin Store onto a microSD card to unlock the specialized Protected Content plug-in.
How Protected Content and ACSM Files Work
Because the compact Xteink devices rely on low-power ESP-32 processors, direct in-device browsing for library books is unsupported. Instead, users borrow titles on separate hardware using Libby, download the associated ACSM file, and transfer it to the microSD card. The CrossPoint Reader built-in web server processes the file utilizing an authorized ByteBooks or legacy Adobe Digital Editions account, converting it into a readable EPUB format.
Streamlining with Common Stacks
For readers looking to bypass manual file transfers, a companion application called Common Stacks—available for Android, Windows, and macOS, with iOS support on the horizon—simplifies the entire workflow. The app manages Libby integration directly and sends files to the X4 Pro with minimal clicks. Although digital library availability still depends on regional OverDrive loan limits, this breakthrough transforms Xteink‘s pocket e-readers into powerful, versatile alternatives to mainstream devices.
