Hardware warning

This firmware has only been physically tested on the older Xteink X4 hardware revision.

The display-driver direction follows the compatible X3/X4 work described by CrossInk v1.5.0-rc-3, which reports fixes for known X3 and X4 display variants and support for the latest X4 battery latch.

X3 compatibility is expected but has not yet been physically tested with Folio Nooir. X4 Pro and S3 models are not supported.

Keep a known-good recovery firmware before flashing. An incompatible display panel or board may require recovery through the SD-card firmware picker.

Installation

  1. Download the release asset named exactly firmware.bin.
  2. Keep a backup of your current working firmware.
  3. Flash using the CrossPoint web flasher or the supported SD-card update method.
  4. Reboot the device after flashing.

Known limitations

  • Bluetooth page-turner/HID support remains experimental and may be unstable.
  • X3 hardware testing is still pending.
  • Some books may require a manual cache refresh after first installation.
  • EPUB compatibility can vary between books depending on their CSS and embedded images.
  • This is an experimental community firmware. Flash at your own risk.

Folio Nooir is built on CrossPoint Reader, with CrossInk used as a reference for compatible Xteink display and reader improvements.
