LG G3 Boot loop, nothing is working.

I have a LG G3 D852 (Rogers Canada) Rooted. I tried to install a software update without knowing that rooted phones will get stuck in a boot loop (firmware update stuck at 0%). So I tried to fix the issue with LG flashtool. Stuck at 6% while unrooting on Wins 10, so I pulled the usb cable out and since then it's been in a boot loop of the LG startup logo. I tried factory reset with Vol Down and Power Button. I can select the options but it just goes back to the boot loop. Please Help!
