Managing Your Mobile Phone
1. On the Settings screen, touch Privacy > Factory data reset.
2. When prompted, touch Reset phone, and then touch Erase
everything. The mobile phone resets the settings to the
original factory settings, and then restarts.
Upgrading the Software Version
Before upgrading the software on your mobile phone, ensure
that your mobile phone is fully charged and the upgrade version
is correct. Back up important infomation such as the contacts,
email messages, files, and other messages saved to your
mobile phone.
Preparing for the Upgrade
1. Download the upgrade file from the appropriate websites.
2. The file you download will be compressed. Use the unzip
software on your PC to decompress the upgrade package.
The upgrade package has a folder structure — be careful you
do not change it. This folder is called dload — do not rename
it, either.
3. Use the USB cable to connect your mobile phone to your PC.
