Ok, I only tried the first one, which does indeed seem to be the actual firmware, but there is something slightly wrong with it. I think there are some leftover checksums.
I removed the lines with 1234567890.. (the last one was the linefeed & carriage return). I did not clean the end of the file, since i could not figure out what to remove. Should I upload the raw (unmodified) dump?
Did you use the exact program I give you to upload in the camera and dump the firmware with? If not, try to use it unmodified.
And what did you use on the PC side to get it?
The exact one did not work, since it was for platform id=31E6, but mine is 31E5. So i had to recompile it with 31E5.
In all cases, at the end, at 4 Mbytes, the load.exe timesout and stops, the camera does not turn off, and the AF led stays on forever (no blinking) so turn off the camera by removing the battery. Is it normal?
