Do you know how to do an md5sum on the DISKBOOT.BIN file?


Alternatively, you could try to attach your DISKBOOT.BIN to a post.

Not sure if I did it correctly, but I unsed onlinemd5.com and dropped DISKBOOT.BIN on it.

It gave this checksum: BF96CD829C589DEFFBB5AA292B85BCB6

Is that what you need ?

Thanks. That looks fine.

Like I said, sometimes I needed to pull the battery multiple times, but
I just found out there is a certain order I need to do.

First I need to put in the batter without SD card, and press the playback button
to turn it on.

Then I press the power button to shut it off.

Then I plug in the SD card and press the playback button.

Then it works 8 out of 10 times until powering down again.

You said you tried a different SD card. Was it the same or a different brand? Can you list which ones you are using?

My original card is a Sandisk Ultra 8 GB 40 MB/S SD HC i
The other one is a 2GB Integral Card it doesn't state the speed.

Also, as reyalp asked, which market was the camera bought in.


Can you also get a firmware dump and upload it somewhere?

Sorry about that, I missed that posting.

It's the European Market (The Netherlands).
How do I do a firmware dump ?

edit:
Looked at the docs and I think i did it. There are now two (512 MB) CRW_0000.jpg files on my card.

Now I have to figure out where to upload them.

I'll get back to you.

There are now two (512 MB) CRW_0000.jpg files on my card.
From size and filename, those are RAM dumps.

The official way to dump the firmware is detailed here: http://chdk.wikia.com/wiki/Canon_Basic/Scripts/Dumper

However, if CHDK runs on your camera, you can use the attached simple Lua script that does the same. Enable the following in CHDK menu before running the script: Miscellaneous stuff -> Enable Lua native calls

The script looks like this:
Code: [Select]
call_event_proc("System.Create")
f=call_event_proc("Fopen_Fut","A/PRIMARY.BIN","w")
call_event_proc("Fwrite_Fut",0xfc000000,0x2000000,1,f)
call_event_proc("Fclose_Fut",f)

If successful, you'll find a file named PRIMARY.BIN in the root of the card.

Thanks for your help. Here is the file:
