Accidentially I own both Canon's camcorder (HV10 although) and camera (ixus65 - which I've ported chdk to).And surely the camcorder hacking ideas and possibility of this was an asspain for me from the very beginning ;)

Right now of what I've tracked down, there is actually a firmware upgrade for the XL-H1 and some owners have it on SD cards. We may probably ask someone (XL H1 Firmware Upgrade Details - The Digital Video Information Network) to share this SD card's content with us.
Minimally, this may give us a clue on how firmware upgrade works.

So, if someone is somehow related to XL-H1 or to people owning it, you may try to help us.

I believe the possibility exists. There is a hack someone found - you may try to press REC and PHOTO buttons in photo mode, and then Power on the camcorder in playback mode. This'll bring up a kind of system screen with internal f/w version and ids. probably it is somehow related with the f/w upgrade.

Surely, there is another way to extract flash memory content out of there. However its a kind of hardcore and requires a special hardware ;)

BTW, head some rumors that the exactly this community (CHDK) could be a reason for canon not to release and allow any public firmware upgrades or information leaks for their HD camcorders ;)

I posted some stuff on their threads over at HV20 - I'm interested in this because if there is a chance an hv20 / hv30 can be hacked - (i.e. we can get it to run arbitrary code or get a firmware dump) I'll definitely buy one of them and get to work on it.

I'm wondering if using Firewire to grab directly at the internal memory of the camera would be a good approach. If the camera has the ability to be put into a "host" mode, I think that firewire's direct memory access might be a great way to bust on in there and get access to the memory. Of course, it would still take a lot of work even if that were possible - but if you could find the program counter and then insert some code to have it basically dump the firmware to memory - and then have some code to read that memory as it is getting dumped... you could obviously stream the firmware off of the camera very quickly.

( See: Physical Access Attacks with Firewire for an introduction to firewire hacking. )

There is a firmware downloadable for a closely related camcorder HF100, and a serial number (listed on an ebay page) was 772632060551

Download was here: http://web.canon.jp/imaging/dcp/ivis/hf10/frm/firmdownload-j.html

Edit: Decoding and other work are continuing in this thread
HF10 (Digic DV II) decrypted!

and at the chdk wiki

Hi,

I'm going to purchase an european hf100 model. Unfortunately it doesn't support 24p but I would prefer this because 25p isn't bluray compliant. I discovered this thread and would like to ask if it's possible to update this device with the firmware from that japanese canon site to "enable" 24p?

And can I switch the display language back to german or english after this update?

thanks and sorry for my english^^

Hi, I'm new here and own an hv20.

Right now on the hv20 forum there's some director/computer programmer who's hacked the HV20, and we're supposed to find out today if it's a ruse or not.... That being said, I would like to know what you guys need to finish this job.  I'd like to help in anyway I could, and if you think you're close perhaps we could set up some sort of paypal firmware business?

PM me or just respond here.

Hi everyone,

I'm a french (so excuse my bad english...) owner of a HV20 and am very interested in having CHDK working on it. It seems that it is not ready now but I could perhaps help going forward.
Could you tell me how to start ?
I have some informatics background (Linux administration, some perl and python, a little C) but not very familiar with low level. So it's time to start learning  :D
And of course I don't want to do anything risky for my cam ... so I can do some tests but only safe ones !!!
