Firmware Update Paths

1. Projector Main Firmware Update

Target Version: V14.0.61.

Path: Settings → System → About → System Update

Estimated Upgrade Time: ~30 minutes (upgrade from Android 11 to Android 14)
Minimum Storage Required: 1 GB free space

Note:

After upgrading from Android 11 to Android 14, some third-party applications may experience issues such as abnormal functioning or stuttering playback. This is due to Google continuously tightening storage access permissions since Android 10, and relevant applications (such as Kodi, VLC, etc.) that require full disk access not being adequately adapted to these changes.

To resolve this, you will need to clear the app data in settings, or uninstall and reinstall the application to restore normal functionality.
