easiest way to find out whether your pine is doing anything is to hook up a serial console to pins 7,8,9 (9 GND) on the EXP connector. note staggered numbering. http://elinux.org/Pine64#Serial_Console I used my ch340g (the one I bought for ESP8266 development, so it has that kind of connector... I just used some male to female jumpers) at 115200. figured out that it was booting, so I let it finish doing the ext4 format thing and then used reboot -p on the serial console to shut down.
in my case the problem was that I only had 1 monitor that would properly support 1080p. you might have some other problem. I took my pine out to the TV after it didn't work with 2 monitors, that worked. So I made space for my other fancy-pants monitor (it was cheap with 3 dead pixels but it's a samsung 25.5 IPS... main one is a burned-in viewsonic 25.5 IPS)
and lo and behold, it worked.
if you interrupted the (lengthy) format process on first boot then you need to start again. the serial console is a way you can keep an eye on the first boot process. an absolute cheapest serial interface should work fine.
I also bought the official power supply. your lg g2 charger might not actually be capable providing 1A, let alone 1.8A. Without an ammeter (You can get a USB power meter for about $5, but you will need wacky cables to use it in this application) it's hard to know. The Pi is also very sensitive to power supplies.
