Hi there!
Due to corporate information security regulations (or your product not being covered by the warranty period), we are unable to provide you with the firmware or address to download the firmware directly.
At the same time, it is recommended that you do not upgrade the firmware version yourself. If the device fails, please contact your local equipment provider or Huawei service hotline. An engineer will then help you identify the problem and provide the appropriate version to resolve.

Of course, you can also send an email to mobile@mail01.huawei.com if you have any questions about Huawei Consumer products.
Thanks!
