Hello everybody Sorry for the approximate translation (google translation) First of all a big thank you to @benrockhold which gives us a solution that works for everyone. Only I block but I do not know where. I explain my procedure: - I download the file - I copy the file to the desktop - I execute "1_FlashFW_Shutdown.bat" From there it went out. I turn it on again but the tactile is always reversed. What should I do ? What is "reflash.exe" for. Thank you all for your help.
