    Hi folks!

    Good and bad news.

    The bad: I'm very short of time this week, so be patient ;)

    The good: today I've been in my local Computer store. I talked to the Chief about Canon Cams. He grinned and said, we will never sell those to our customers again ... then he showed me his collection of bricked Canon Cams.

    I got now an ixus i7 with Lens error for free (and another battery ;) ) I used some violence to resurrect it. Here we go: http://chdk.wikia.com/wiki/SD40
    I hope, this will help me to understand, how the udumper works. It obviously doesn't work with the SD1100.

    @jeff666: ok. I'll try that but first I need to get a Phototransostor somewhere.

    Just a short update. I found LED_AF  @ 0xc0223030

    blinker is running but need better adjustment. The recording looks odd.

    Stay tuned ;)

    ok, and here is a crypted diskboot.bin with blinker inside.

    Just in case anyone else want to give it a try.

    How does the encryption work?
    Would be great if you could paste some code.

    I agree. A description or code would be great.

    Have you tried to encode the udumper and dump the firmware using that?

    Cheers

    Very interested in seeing this too... trying to dump the SD790IS, and seems to have similar problems to what you're trying to solve...

    Great work!

    I confirm the encrypted blinker works on my SD890IS (IXUS 970), and the AF LED must be at the same address, because it turns on immediately and is blinking.  I will build the receiver circuit soon and attempt a dump.

    If you have time to very briefly describe what encryption was required, that would be great.  As jeff666 says, it would be great to try encrypting the udumper program in the same fashion, to see if we can avoid having to set up the full blinker toolchain.
