Hello, dear.
I cannot get the reason for the upgrade failure from the information you provided. You can first check whether the communication connection between eSight and the terminal is smooth, and then perform the upgrade again. You can also check whether eSight has been upgraded to the latest version. If the upgrade still fails, it is recommended that you contact your local Huawei representative office for professional support. Escalation is a risky operation.
