So you need to install the appropriate drivers on your PC, if not already installed.
Then you can make a backup just in case.
After that use SP-Flashtool to flash the autoCWM-recovery.
Thank you to both of you Mirchichamu and Thor
I think you are right : I should not be too much bothered by the fact that fastboot does not work.
You give me some hope that my phone is not completely broken when you say
"Flashing with SP-Flashtool doesn't need a working/booting phone."
I tried to follow Thor's cookbook but unsuccessfully:
Hopefully I was able to create a scattered file on my PC before I bricked it.
But I am now stucked in step 14 : the progress bar show 0% and does not progress.
Probably my drivers are not correctly set-up.
Drivers on Windows are not "plug and play" but "plug and pray"
When I plug my phone (unpowered), USBDeview shows activ device "Preloader USB VCOM Port"
But nothing in Windows Device Manager.
I hate windows and drivers. I think I will have to setup a clean Windows to have working drivers :-/
Thank you to both of you my friends. I do not feel too much lonely now because you answered me kindly
