Folio Nooir — Preview Release
Folio Nooir introduces a bookshelf-focused reading experience for the Xteink X4.
⚠️ Hardware warningThis build has only been tested on the older Xteink X4 hardware revision. Do not install it on newer X3/X4 display models unless compatibility has been confirmed.
Highlights
- New Folio Nooir bookshelf interface
- Library, Recent and Finished sections
- Cover, title, author, synopsis and progress display
- Persistent Reading, On Hold and Finished states
- Daily reading time and finished-book statistics
- Improved EPUB CSS, tables, images and metadata
- Typography controls displayed in points
- Faster cached bookshelf loading
- Web-based library and file transfer
- Custom BMP and PNG sleep images
- New Folio Nooir boot logo
Book actions
Long-press a book to:
- Mark it as Reading, On Hold or Finished
- Reset its reading progress
- Refresh its metadata and cover cache
- Remove it from Recent/Finished without deleting the ebook
Clear Reading Cache now also clears stale Recent and Finished entries. Your ebook files are not deleted.
Known limitations
- Bluetooth remote support remains experimental and may cause instability.
- Some complex EPUB layouts and CSS may not render exactly like a desktop browser.
- The first cover or metadata extraction may take a moment.
- Only the older Xteink X4 has been physically tested.
Installation
Download the .bin file and select it through the CrossPoint web flasher’s custom-firmware option.
Keep a copy of your previous working firmware before flashing.
