Hi, I'm new here. I would like to modify the 7D firmware.
I don't really understand this conversation...
Is this about the two tables which XOR the firmware file payload?
Something like dissect_fw do?
Are these tables different in different cameras or firmwares?
I thought these are constant values.
I've just made a simple tool to 'unpack' the newest DSLR's .fir files and I've burned in this two table to my app.

Edit:
The program developed based on the information about firmware structure discovered by arm.indy.

Yes, thank you. I've corrected the link.
