Hi Guys,
I'm an experienced SW Developer, but new to this. Does anyone have a 450D firmware dump I can have a look at? I tried the russian link at the top but couldn't get it to download. Thanks in advance!

Ok, I was hoping someone had already decrypted it. Can anyone suggest the best tool, or is the LED method most favoured for this? Thanks in advance.

you can decrypt first part of firmware file - "flasher"

r00f used firmware update file modification method to run some code on camera.
I would say it is only way to launch initial code on your cam.

and storing ROM dump into file is more efficient one comparing to blinking out it via LED :-)

You can try to track down initial dumper sources and dump it yourself.
I will look into it later and maybe will help with this if you have problems.

one more benefit of dumping ROM instead of decrypting update file is - you get full ROM instead of partial updated areas...

Hi mx3,

Thanks for clarifying that, and sorry for the late reply. I'll give r00f's method a go and post back here with my results

Hi guys, I'm new in the forum and I don't understand much about software engineering. I see that rhis post is not updated for a long time, does it mean that nobody could hack the 450D software?
