I don't know how I missed this post before, but I'm very much interested in these files (!!)..
Being able to update firmware from SD card would be a big step forward.

I've been looking a bit at the E-P1's firmware and it also contains references to these Exxxyyyy.BIN, etc. files (xxx = model id, yyyy = version). There's also a string "dcolymp", etc. So this looks promising.

I made a little tool that can do packing and unpacking; and some crude statistical analysis to estimate loading address (for E-P1 firmware for instance, it is not the value in the code block's header 0x40060000, but the slightly more exotic 0x6F191420.

I checked the firmware's descrambling and checksum computation routines in IDA and it seems correct.

Will send email to mx3 and foxo..

Hello I have a SP-800UZ olympus camera. As there is not a firmware available for it, i got the SP-600UZ fw from olympus and have decrypt it using basically the same algorithm you mentioned before. ( I wish i knew it earlier :p) I found out the files contained by using mx3's unpacker, which has basically the same structure as some CP Nikons (8800,5700,5600..) and Fuji cameras as mentrioned. The thing is that I can not continue from here. I cannot figure out the structure of each file exctracted.

Maybe someone could provide some hints for how should i continue from now?

I also have tested the already known firmware file onto the camera's memory and seems to work great, so I should be able to upload the modified firmware easily.
Thanks

Hello, everyone!
I have the Olympus E3's CF-Card-Upgrade firmware file of version 1.003/1.102/1.203, and we can do fw upgrade or downgrade by exacting these files to the CF card's root directory "dcolymp", and turn on power when pressing the OK button.(Not by the master or studio, the Custom Service also did by this way)
If someone has the ability to hack it or want to research it, you can email to me, i will sent you a copy.

Please, send me this copy to e-mail:dmpolg@gmail.com
