Thank you for your answer.Do Flash by using flash tool provided at post #6
Follow the steps and then wipe all the data/ format the phone and after reboot... phone will work fine and touch issue would get resolved.
I would have a last question about the flash tool, what is the good manner to flash it, in adb what is the right command ? Thanks in advance.
Edit: OK i Just click on bat... Seems OK. I still have touch screen error.
I'll begin again since the begining ^^
