I have an IXUS 95 IS, and using the ver.req file, I see version 1.00C.
I then unzip this package ( ixus95_sd1200-100c-1.0.0-1659-full_BETA.zip ) into my card, then I get to the "firm update" by powering on using the play button. Then when I hit OK to update from 184.108.40.206 to 220.127.116.11, I get a red CHDK logo for half a second, then it goes back to "no image".
And I think the firmware update failed, and there is no effect on the camera. If I repeat going to "firm update" I see the same offer to go from 18.104.22.168 to 22.214.171.124
I do not get anywhere from a locked card.
Do I have to make some changes to the CHDK files for this camera?
And this camera doesn't have a "Direct Print" button, so I've seen mention of using quick press / long press of certain buttons... but I'm not sure..
