I'm not a owner of any dsrl.
I just want to repeat some "known" facts:
- there are no problems with decryption of official FW so you actually do not need to make dump to analyse FW.
- no one with programming skills have done anything usefull for quite long time for this type of camera.
- this camera is outdated by now and maybe it explains why there are no more attempts to hack it.

i'm not sure how could you use 40D packer to make .fir file which could work on 350D.

update: changed 400d to 40D

Thanks mx3,

I use the entry.s and scanled.c only with the below commands,

arm-elf-gcc -fno-builtin -O2 -Ilib -nostdinc -c entry.s
arm-elf-gcc -fno-builtin -O1 -Ilib -c scanled.c
arm-elf-gcc -fno-builtin -O2 -Ilib -nostdlib -Wl,-N,-Ttext,1900 -o scanled.exec entry.o scanled.o -lgcc
arm-elf-objcopy -O binary scanled.exec scanled.bin
decrypt20d.exe scanled.bin scanled.fir
