Canon firmware updates[]


This section describes the procedure to update the camera with a permanent Canon firmware update - do it on your own risk !

NOTE: Upgrading from 1.00f to 1.10a was performed on a Linux box (Ubuntu 11.10 )

If you decide to try this, you do so entirely at your own risk !

The procedure is as folows:

  • Obtain the firmware from Canon via their support pages, the exact version will depend on what is available and possibly which country you are in. For the main site in Japan you could try here:
  • Enter your serial number (for example 2331004974 ) and click the "I Agree" button.
  • On the next page, select the Windows updater, ixusw_firm_win-e.exe and download it.
  • Once downloaded, open with File Roller (which can extract the contents of Windows Executables, sudo apt-get install file-roller if you dont have it), and extract just the file named IXY_WiFi.FIR
  • Rename the extracted file as PS.FIR and copy to the root of your SD card. Now power up the camera in playback mode, and use the "Firm Update" menu item to upgrade the firmare.
