Unlock the activation lock by resetting the device: Select "Restore Factory Settings" in the settings, and select "Reset Device" in the pop-up window to start the reset process.
Use third-party software: There are some softwares specially designed to unlock Huawei mobile phones, but these softwares may be risky. Please choose carefully and make sure to download from official channels.
Contact after-sales service: If all the above methods fail, it is recommended to contact Huawei's after-sales service department for help. They will provide more professional technical support and can help you complete the activation lock release process.
It is important to note that before any operation, please ensure that all important data are backed up, and understand the restrictions on equipment warranty policies and terms in your region. In addition, if you have other security problems or need more help, please feel free to consult Huawei's official customer service staff.
