ZTE Blade V10 Vita Upgrade Guide (Through an SD Card)
1. Cautions
The software version and pictures in this document are just for
reference only. Please use ZTE handset support website provided version
to download software.
1) Download the upgrade package.
Open http://www.ztedevice.com.cn/support and download the upgrade
package (update.zip) that matches your phone model. If the
downloaded package is not update.zip, unzip the package to obtain
update.zip.
Ensure that your micro SD card is at least 2GB.
Note：Please refer to our current version download size.
2) Remove the SIM card, then back up the data and APPs in your phone
before the upgrade.
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.
4) Verify that the update.zip file in the root directory of the SD card
matches the model of the phone. Do not modify the file name and
extension name of the files in the upgrade package.
5) Verify that your phone has enough (at least 40%) 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.
6) You should not perform any other operation on the phone during the
upgrade process.
7) A normal upgrade should be completed in 10 minutes. If the phone does
not reboot or show any response in 10 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
.
2. Upgrade Description
There are two upgrade methods: normal upgrade and forced upgrade.
If the phone cannot be started properly, for example, the phone cannot be
started, or the phone does not enter standby state, perform a forced upgrade.
If the phone can be started properly and the Settings menu can be selected,
perform a normal upgrade.
