How does Huawei Mobile 8.0 system fall back to the previous version?

Asked by: Roberts 194 views Phone & Tablet February 13, 2019

The phone that was originally very smooth, after updating the new version of the system, Karton can't, especially the network, not only slow into a dog, but also often jam. I remember that there was a way to retreat when I updated it, so I updated it, but I can't find it now. Which big god knows how to roll back? Thank you! If you successfully roll back an additional 100 reward points

    Download and install Huawei mobile assistant on the computer (software can go Huawei official website download)

    Run the software and connect the phone (the connection is to pay attention to the prompts on the computer and operate according to the requirements)

    After the connection is successful, enter the system upgrade, there can be a fallback All previous system options

    Question: Can’t operate. After connecting the mobile phone, the prompt to install the new mobile assistant on the mobile phone pops up, confirm the installation and display the connection is displayed after the installation is successful, but then continue to pop up the installation mobile assistant prompt, and this is repeated, that is, the mobile assistant cannot be installed on the mobile phone. In the application market on the mobile phone, there is no so-called mobile assistant.

    Unable to roll back after updating the system, only the factory settings can be restored. However, restoring the factory settings will delete the data in the phone. It is best to back up before recovery.
