Dump Ixus 960is

Hi @ all,
yesterday i finally got my new Canon Ixus 960 Is and would like to make a dump in hope to soon be able to use chdk on it.
But i'm new to firmwaredumping.

I Planned to use the led-blinker-way and buy a phototransistor today, i allready found a shop, where to buy here in berlin.
But now i read something about a new way without a cable etc. Just with a dumping-software on the sdcard.

My question is now: is this way allready available and "user-friendly"? :)
If it allready exists, is this kind of software allready usable, and where can it be found?

if it still does'nt work, i will blink the code, but then, where can i find the blinker-code?
as all links i found are outdated and not available anymore, please help me to enrich the kit with a new great canon-cam.

Thanks and greets from berlin/germany
TK

You probably mean ewavr's universal dumper here: udumper

It is very convenient - the only 'drawback is that it does not give any feedback.
method:

- format a small (16M - 1G ) card in camera (avoid 2G and bigger)
- apply bootable.exe (in archive) on it (to make your cam recognize it as 'bootable')
- copy 'empty.dum' to the card
- copy one of the 'diskboot.bin' files to the card, choice depends on your cam OS.
  if you don't know, you'll have to try them until you succeed.
- write protect (w/ small tab on card) and insert card
- start cam in Review, not picture taking mode
- NOTHING will happen, don't worry, wait ~ 1 minute to be sure
- open battery compartment and remove battery
- remove card
- open 'empty.dum' in your favourite hex editor, if it contains anything apart from binary zeroes, you got it
- otherwise, start again with next 'diskboot.bin'
- to clean up you can remove 0x00's from the beginning of the file & 0xFF's from the tail end.

A VxWorks cam will have 'Copyright 1999-2001 ARM Limited' or similar at the beginning of the dump
In a DryOS cam the first bytes sofar have always been 'gaonisoyP'

hope this can save you from the much more complicated (?) blinking method

good luck & let us know how you get along,

wim

@ewavr

sorry, i forgot about locking the card  - corrected

BTW what time would you recommend, is 1 min too much ?  And another Q if I may,
is there a preferred trying sequence (I mean DryOs -> VxW large -> VxW small or something)

5-10 sec. (write speed is above 1 Mb/s).

Maybe DRYOS for new cameras, VxWorks for old ones? ;)

It would be great to put this instruction in Wiki.

Wow - firmware dumping has really become easy. It took me a whole weekend to dump my cam, but that was ages ago, of course (which means: last november :D).

Also the amount of dyros-cams is increasing. How fortunate someone figured out how those work 8)

Cheers.

Yes. Your work was very helpful when I ported SD870. The port is based on your code. With the comments it was not so difficult to do (despite it was my first port :) ). Thank You!
