1- About the french firmware are you sure it's an Official one?
Samfirmware's website firmware are the official ones. That's why I asked you to get one from there.
2- For the cable, use the one that you got with the phone. Probably if you used kies before you have the drivers installed.
What you need to do is remove the battery plug the S2 to your computer place the battery, and odin should see it.
(if Odin didn't see it try to do the button combinations until odin sees it)
and then you will be able to flash it.
Try to flash ur french firmware using this method (the cable that u got with the phone) as long as it is an official firmware
(forget pit file it can work without it)
