Is there any way to alter the initialization procedures the camera goes through when it boots up? Im doing a project trying to replace the lens on elph 100hs with a c mount lens. The camera seems to be trying to check for a working lens when it boots up though. Any ideas?

You probably want to take a careful look at this :   http://chdk.wikia.com/wiki/User:Srsa_4c/Working_with_a_broken_camera

The links at the bottom of that page are very useful too - especially this one :  https://chdk.setepontos.com/index.php?topic=8801

Hi Waterwingz,

Thanks for the resources! Correct me if I'm wrong, but from what I understood, I have two options.

1. Use the DisableLenseError command though CHDK PTP to get the camera to boot up without checking for a functioning lens. I'm still learning about all that, so that might not be the right way to say it, but hopefully you get what I'm trying to say.

2. Physically cut away everything except the focus/zoom motors and sensors so the lens is gone, but the camera still detects the same results from it's sensors.

I managed to tear one of the ribbon cables off, so I'll definitely have to get a new lens assembly to try #2, however, I think I may need a new lens to try #1 too; ever since I tore that cable, I can't get CHDK to show up as a firmware update. I'm thinking maybe I should get the thing functioning with the lens first so I can fix one symptom at a time.

Do you think this is the best course of action? Thanks for the help!

Sorry - I just posted a few links by people who have gone down your path that I remembered reading.  I've never tried anything like this myself.

One thing that I can suggest though is to figure out how to get your camera to autoboot with the SD card lock method.  You want CHDK loaded before the camera firmware starts doing much of anything.  Using the firmware update method of loading CHDK will not help you with that.
