If no models are displayed after updating the machine and you only see “K_product”, this is usually because the APP data loading process was interrupted after the upgrade, resulting in incomplete data.
Solution
Please restore the machine to factory settings, and then upgrade the APP again.
Important Note
After upgrading the machine, please be patient and allow the APP to fully load and download all required data during the first startup.
Do not interrupt the loading process or turn off the machine before it is complete, as this may cause incomplete data and errors such as “K_product”.
