Thank you for your message. Our latest OTA base version is 3.0.0, which includes major improvements for OTA downloading, MCU optimization, and UI adjustments. However, because this version is currently under compatibility testing for all models, it has not been released publicly yet.
If you would like early access via USB upgrade, please send me your current system version information, After I confirm your model, I will provide you with the correct upgrade package and detailed USB installation steps.
