Updating Software
Software Update
Software Update is a function that connects to the network to check whether software on
FOMA terminal needs to be updated, downloads the software by packet communication as
and when required, and updates the software.
The NTT DOCOMO website provides information about required software updates.
NOTE
You can update software while still retaining data (such as contacts, camera images,
downloaded data, etc.) on the FOMA terminal. Please note, however, that such data may not
be protected, depending on the state of the FOMA terminal (malfunction, damage, exposure
to water, etc.). It is recommended to back up necessary data. Please note that some data,
such as downloaded data, cannot be backed up.
Before updating software
Do not remove the battery pack while updating software. This may result in a failed update.
Fully charge the battery pack before updating software.
Software cannot be updated in the following circumstances.
•
When the battery level is too low for software update
•
When there is insufficient free space in microSD card for software update
Software update (download, installation) may take a long time.
During a software installation, you cannot make or receive calls, or use any functions (voice
calls can be received and some function can be used during downloading).
When updating software, the FOMA terminal performs SSL/TLS communication with the
server (the server for software updating managed by DOCOMO).
If the software has already been updated, "No update is needed." appears when you check
for software updates.
