*First reomve battery connecter and connect test points then attach USB CABLE.
*You have to notice that when the process of flashing is started the Dongle will do some work and will reboot device into fastboot mode , Now we have to reconnect battery (timing is very important) so the device will get into fastboot mode. and then the Dongle will continue the process od unbick and device will bootup successfully .
Now device will work with No Voice Calls and some bugs .

Once Board firmware flashing is done , device will boot up without IMEI so we have to flash any stock rom with SD Card Or via EFT Pro .. and device will be woorking like a charm.
