Change port to 41 and see if the tool detects the phone, keep it for charging for a.few hours, see if the phone heats, power button hold for 15 secs then while the comport is 41 connect the phone pressing volume down, see if it detects on flash tool, try and flash zvc. If it gives fail, try a diff comp. Diff usb cable. Same problem a friend had. Keep trying to flash.
