Firmware Version 188.8.131.52.00 is only for EOS C300 cameras which have Firmware Version 184.108.40.206.00 - 220.127.116.11.00 with the Dual Pixel CMOS AF Feature Upgrade applied. If your camera’s firmware is already version 18.104.22.168.00, it is not necessary to update the firmware. Once the camera is updated to the latest firmware version, it cannot be restored to a previous version.
If the EOS C300 camera does not have Dual Pixel CMOS AF Feature Upgrade applied, please download Firmware Version 22.214.171.124.00.
Preparations for a firmware update:
After the Firmware update has been performed, the camera’s menu settings and custom picture settings will be reset. It is recommended that users save their menu and custom picture settings as settings data to an SD card, separate from the one that will be used to carry out the update, before starting update operations. This saved data can be loaded into the camera and the settings can be changed after the update has been completed. For further information on this, please refer to the section in the camera’s user manual titled Saving and Loading Camera Settings.
The downloaded firmware folder contains the firmware (File Name: VKL8.FIM, File Size: 35,066,960 bytes) and a procedure manual for updating the firmware (a PDF file in five languages: Japanese, English, French, Spanish and Simplified Chinese). Please check the firmware update procedure manual carefully before starting update operations.
