CrossRhythm gives the Xteink X4 Pro a better reading rhythm
Free, open-source firmware for the Xteink X4 Pro adds Indic-script rendering, an on-screen charging display, and detailed reading history.
- For
- Xteink X4 Pro readers of Indic-language books
- Worth noticing
- Kannada, Tamil, Malayalam, Telugu and Devanagari support is tested on-device; Bengali and Odia remain experimental.
Field notes
The firmware carries CrossInk reading history forward, but its older per-book totals are estimates spread across the days read; sessions after installation produce recorded daily activity and streaks. Its sleep-screen options include a charging scene and a reading-progress scene, alongside monochrome bitmap wallpapers with a Page Overlay option. The page says Kannada, Tamil, Malayalam, Telugu, Hindi, Marathi, and Sanskrit are supported, while Bengali and Odia remain experimental.
