Software Update Cautions
During update: The phone cannot be used until the software update is complete. It may take time to
update your phone’s software.
Signal during update: Update your phone where signal reception is good, and do not change
location during the update process. Make sure the battery is adequately charged before beginning an
update. A weak signal or low battery during an update may cause the update to fail. An update failure
may disable the phone.
Other functions during update: Other phone functions cannot be used during a software update.
Update Your Phone Software

your phone firmware.

personal information.
