hi - downloaded v4 and gt loader and 400 bin file keep getting message when trying to flash box "UNABLE TO OPEN SERIAL PORT" any idea's . thx
go to my computer then right click go yo properties.click on the hardware tab.in the hardware tab in the middle box click on device manager.look for ports(com&lpt) its near the end of the list.click on the + .now it will tell you what ports you have eg.communications port (com 1).whatever port it says go to gtrom loader and make sure the com ports are the same.if ti says com port 3in device manager then change the com port on gtrom loader to com port 3
