card updates. If the downloaded package is not update.zip, unzip
the package to obtain update.zip.
 Get a blank micro SD card （at least 1GB）.
2) Remove the SIM card before the upgrade. Back up the data and APPs in
your phone by using a third-party PC tool (Wandoujia or 91assitant) or the
built-in Backup function. To enable the built-in Backup function of your
phone (an SD card must be inserted), select Backup and Restore from
the main menu, see Figure 1-1.
3) Perform data backup.
Note:
You should not remove the SD card during the backup process. To avoid
data lost, it is not recommended to cancel the backup process.
Verify that your phone has enough (at least 20%) power. Charge the phone

if required. To avoid data lost or upgrade failure, it is not recommended to
upgrade your phone through an SD card when the phone is being charged.
Note:
You should not perform any other operation on the phone during the upgrade
process. To avoid upgrade failure, do not forcibly remove the battery.
A normal upgrade should be completed in 2-3 minutes. If the phone does not
reboot or show any response in three minutes, you should perform the
upgrade process again. If the phone cannot be started, perform a forced
upgrade. If the forced upgrade does not work, you should contact an after-sale
service agent for support.
