If I connect it to a wall charger the screen turns on with the battery icon and the red light blinking. I have drained the battery and tried the battery calibration trick (holding power and the vol + - buttons while using a bright light) and it has not worked.

When I plug it to my Windows PC it is not recognized except for today when it got recognized while I tried the battery calibration trick but the driver that was installed was something like this: Qualcomm HS-USB QDLoader 9008. I read in another thread that a user went through the same thin and some of the comments simply recommended him to take it to a store or that his motherboard was fried.

Is my phone bricked? Since I am not yet sure about this. And if not, is there a way to bring it back?

unfortunately QHSUSB_DLOAD mode means, as you said, a defective motherboard. You'll have to send the phone for repair.
