A community project replaces Xteink’s stock firmware with an open one: full EPUB rendering, KOReader progress sync, Calibre and OPDS libraries, custom fonts, Bluetooth page turners and over-the-air updates.
- ai
- The repo ships Claude agent instructions; the maintainers do not say how much of the code AI wrote.
- caveats
- Some units sold through third parties are USB-locked and need the project's unlocker first; flashing a locked unit wrongly can leave it unrecoverable. You can return to the official firmware.
- evidence
- Public repo, very active.
