I have a MTK6582 Smartphone (LEO DG280 from Doogee) after i bought this phone i had some problems with the Touch Screen he not responding anymore. That´s why i take the decision to load the new firmware from the Doogee Homepage after I download it and install the (FLASH TOOL 5.1343.01) and Install the (MediaTek USB VCOM drivers) manually by ignoring the signature i get the (code10 error) if i do ignore this error and start use the Flash Tools (nothing happen) The Phone can´t switch to META mode even if i push the switch off button and the volume up/down button at the same time . The Phone recognize by my computer only as ( MTK USB Port (COMx) I use an Windows 7 64bit Computer and of course i install the 64bit Mediatek Drivers. I restart the computer after install the drivers and i have reinstall the drivers too by using USBdeview of course i start all tool as Administrator before . I try to use older versions of Flash Tools but the problem still be the same . After 7 minutes of waiting the Flash Tools show up this message : (BROM ERROR : S_FT_DA_NO_RESPONSE (4001)) "DA didn´t send response data to Flash Tool"
