@raibikash Hi, your moto g2 is hard bricked now and wont boot up until you get your motherboard either repair(Flashing Bootloader and other initial programs through Flash box like jtag or sigmakey) or replaced. i want to share something, i have a moto g2 in same condition as yours, i replaced its battery but finally get to know that it gone hard bricked. so my phones battery was ok but the motherboard having the problem. so i sucked up... wasted my time and money in trying to fix it. it just a paper weight unless i replace its motherboard. just a piece of advice, if you still want to repair your device then bring it to service center technician.
