Software Update for F905i


NTT DoCoMo announced today a minor update to software for F905i. We encourage our users to make this software update to improve mobile phone performance as shown below.

This update fixes the following issue:

  • Music&Video Channel1 programs or Video Clips2 that have been downloaded and saved may not play back correctly, and the sound and video may be out of sync.
      1 Music&Video Channel is a service that automatically performs overnight downloads of programs of up to approximately one hour in length (approx. 30 minutes of video).
      2 Video Clips are video files of up to 10 MB that can be downloaded by i-mode.
  • When attempting to confirm your current location (GPS positioning) with features such as GPS-compatible i-αppli, positioning may not be possible under certain conditions. A message indicating that confirmation of your current location failed will display in that case.
      Even after downloading the software update, the message indicating that confirmation of your current location failed may still display when satellite signals cannot be correctly received. This is a normal occurrence.
  • Software update may fail in some cases.
      Even if you have already made the software update available on January 31, please update the software again.

1. Notes


  It takes approximately 24 minutes to download and update software. Please note that the mobile phone will not be available for use during this time. The Timer Update function will enable you to perform software updates while you are asleep or other times that are convenient for you, so we recommend that you take advantage of this function.
Also note that you should never remove the battery pack while updating software, as it will cause the phone to malfunction.
  Updates of the software can be done while keeping Phonebook entries, camera images, downloaded data and other data saved on the phone intact. However, please note that in some cases data cannot be protected depending on the condition of your mobile phone (malfunction, damage, water exposure, etc.). It is recommended that you back up necessary data.

2. How to Update your Software


New software is automatically downloaded and overwrites the existing software at a preset time (default time is 3 a.m.).
Updates can also be made as desired by conducting the operation below and following the instructions on the screen.
In standby, press the "MENU" button then select "Settings & NW services" → "Other" → "Software update".
