{Z3-DUAL} UNABLE TO ENTER FLASH MODE (led blinks red & then green for half a second)

I Am trying to access flash mode to flash a firmware via flash tool. But when i try to enter flash mode (by pressing volume down and connecting the USB cable) Phone will only blink red and then green for a half second and the nothing.

But fast boot and recovery mode works fine.

I have custom ROM installed but flash mode did not work even when i had stock firmware.

Please help and Thanks in advance
