CPR-vCodex

CPR-vCodex

v1.1.17-vcodex X4
18 stars Last release: Apr 2026

CPR-vCodex builds on the great work of CrossPoint Reader. This firmware line starts from CrossPoint Reader 1.1.1 and has been extended and improved with the help of OpenAI Codex for the Xteink X4.

It keeps the strong CrossPoint base and adds a more polished day-to-day reading experience:

  • better Home workflow
  • configurable Home and Apps shortcuts
  • coherent date-based reading stats
  • heatmap and per-day views
  • achievements
  • built-in ReadMe guide on device
  • EPUB bookmarks with a global app
  • visible firmware version code on boot
