Why did you unlocked the bootloader? are you certain that you indeed unlocked the bootloader or were you on the process of unlocking it?

You didn't had to do that, you could've just flashed your phone with flashtool w/o having to unlocked the bootloader, does it charge at all?

try this

connect your phone to a wall charger > press and hold power & volume up for 10 seconds > let it charge for 1 or 2 hours > then try again
