• V1.0.4.9 (Transition Firmware): Unifies firmware upgrade packages and updates both the startup and video output logos to HOLLYLAND. Devices running firmware earlier than V1.0.4.9 must install this transition firmware before upgrading to the latest version. Devices running V1.0.4.9 or later do not require this transition update.
• Upgrade may cause unknown errors. Avoid upgrading when you need to use it.
