What are the possible reasons for the app interface message "Upgrade failed, possibly due to weak signal, please check the device network and try again"?
Last Updated on：2025-09-01 02:56:58
Possible situations are as follows:
- Network speed issues, leading to untimely progress reporting or difficulty in downloading the upgrade package;
- Device upgrade conditions are not met, mostly due to business logic restrictions, such as not being connected to a charging pile or battery level being below the set threshold;
- Version number reporting timeout, device upgrade failure resulting in no new version number being reported or the device taking a long time to connect to the network after reboot;
