When I turn ON, my LG G2 (D802) unpredictable some times
- works perfectly
- sticks on LG Logo for hours
- sticks on LG logo for hours with blinking green and light blue led (some time with hot battery)

what do you suggest? Could be an hardware problem?

Everything starts after replacing battery, then I upgraded to lollipop (though official lg windows software) and root phone (through LG root script). After 3 or 4 weeks, it suddenly begin to have that issues.
The problem is that when it works I can do everything (also re-install stock rom), but today works, yesterday didn't

If you still have problems try reinstalling stick ROM and uproot the device. From the past paragraph, it seems like it was working today.

During the moments when phone works, I already restore original lollipop Stock Firmware (through KDZ Method/LGFlashTool2014.exe)
(I thing phone came back unroot in this way) but problem is still there

I'm now having this problem too. I'm rooted, but stock. Did you ever get it figured out?

Unlucky not.
Phone still continues casually to work or to not work
And you?
I think is an hardware problem
I read that many G4 have a problem due to motherboard

I actually got it to work by flashing the stock firmware and then starting from scratch.
