How to upgrade Huawei’s mobile phone system How to upgrade Huawei’s mobile phone system [Detailed explanation]

　　Huawei’s mobile phones use Android, and there are many ways to upgrade. You can choose to upgrade according to different conditions.

　　Two Methods of Huawei’s Mobile Phone Upgrade System

　　Method 1: Mobile phone networking update

　　First, connect the mobile phone to the internet.

　　Click Settings.

　　Drag down and click on the last item "About mobile phone"

　　Click "System Software Update".

　　Click on the online upgrade. Friendly reminder: system update will erase a lot of data including information and address book, and all the software installed by yourself will be cleared, so you must make a complete backup before updating.

　　Method 2: Local update

　　The first method is the simplest, but the system update package is generally tens of meters. If the mobile phone traffic is not enough, the following method is recommended.

　　Log in to Huawei official website and click "Personal and Home Users".

　　Drag the page to the bottom and click "Software Download".

　　Select "Smartphone" in the product category drop-down box.

　　Then select the product model (pay attention to distinguish the version of the mobile phone operator) and click Submit.

　　Download the update package. In this way, the update package (usually compressed package) is generally very large, basically hundreds of meters. After downloading, it will be decompressed. Put the decompressed file on the SD card of the mobile phone.

　　Unplug the data cable and select local upgrade in the phone settings.

　　Also back up important data in advance.

　　Note: Be sure to back up important data before updating.
