You are left out with very few options as you have bricked your mtk6575 chip set device, default firmwares are very hard to find for these types of chipset. The warranty on your smart phone is also void now as you have bricked it up but then also if you want to recover your device, the best option is to take it the manufacturer’s prescribed service center. It may cost you some amount of money but it is the most reliable option for you at the present time.
