When a Wi-Fi network is available, the phone
downloads the upgrade package and automatically
carries out the upgrade.
Before the upgrade, ensure that:
You have backed up important data on the phone because software upgrades will erase
all user data.
The power remaining of the battery is more than 50%. It is recommended that you
connect the phone to its power adapter for power supply and do not remove its battery
during the upgrade.

You have checked the phone software version because the software upgrade aims to
upgrade lower versions to higher versions only. For details about how to distinguish
between versions, see section 5.3 "How to Distinguish Between Software Versions."
If a normal upgrade fails, use the forcible upgrade method to upgrade the phone again.
Prioritize the normal upgrade on phones that can be normally powered on. Forcible upgrades
may be risky because information loss might happen and thus is not recommended.
About backing up important user data:
To back up contact information, text messages, and third-party applications, insert a
microSD card, and use the backup software on the phone (All Backup, for example) to
back up all the information to the microSD card.
To back up photos, videos, music, and personal files, manually back them up to the
microSD card.
5.2 Checking the Software Version
To check a phone's software version, touch Settings > About phone > Build number.
