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 15%. 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. Upgrades between phones used in
different countries and between different customized phone versions are not supported.
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 may occur. Therefore, do not forcibly upgrade the
phone.
