The hard reset method for the LG G2: Thought I bricked my LG G2 because a Rom failed to flash and all I could boot was the LG logo and a fail screen. After googling I found the hard reset method and I was saved. Ohhhh lawd. So you hold volume down and power, then let go of power briefly once the LG screen appears, then let go of volume and hold power. A hard reset screen appears, hit power 3 times and it will wipe everything and take you to the recovery screen, that is if you still have one. If not you will have to adb push like I had to do and if you don't know how to do that then you shouldn't be rooted. But let me tell you...what a pain in the ass. Never flashing anything outside of Cyanogen, Liquid or stock rooted again.
