Online upgrade of mobile phone firmware/system

It is recommended to use Fota to upgrade the mobile phone firmware/system online. Please operate: Settings-System Update-Download Update Manually/Download Update Automatically (Software Update/System Update-Update).

Backup data before upgrading

Please back up the data in the device before upgrading to avoid data loss and unrecoverability.

Upgrade time and power consumption

The mobile phone needs to be set to the current time. The mobile phone is fully charged (more than 50%).

Storage space and network environment

The mobile phone needs to have enough storage space (at least 1GB USB memory). Ensure the stability of the network environment (the updated version of the system/firmware is large, which may consume more traffic, so it is recommended to use WLAN to access the Internet when upgrading).

Security upgrade of service center

If you can't upgrade normally through the above methods, it is recommended to bring three-guarantee vouchers and send the mobile phone to the local service center for security upgrade.
