Hi I have a powershot 780is that runs the B version firmware.... The canon page doesn't have the C firmware upgrade to upload... but on one of the pages here someone posted the C version for development purposes... can that be loaded to my camera to replace the B version, and allow me to use the CHDK that is only available for the C???? if so how can it be done? thanks!!!

im not sure how this works... please email me a response at

thanks so much!



I have a canon powershot A720 IS, and I would like to know whether this model's firmware can also be changed with CHDK ? If so, is it possible to direct it with a computer through a usb cable ? I want to fix the camera and use my computer screen to see the image the camera detects live, change exposure or diaphragm ...

Is this possible ?

Thanks a lot for your help 20:29, May 1, 2014 (UTC)
